Engineering Selection Recommendations

Direct Parametric Equivalents (Identical Electrical Specifications):

SS1H10-E3/61T is the direct equivalent of SS1H10-E3/5AT from the same manufacturer. Both parts share identical electrical ratings (100V, 1A, 770mV forward voltage, 1µA reverse leakage) and maximum junction temperature (175°C). The only difference is packaging format: SS1H10-E3/61T is supplied in Cut Tape (CT) & Digi-Reel® format instead of Tape & Reel (TR). This substitute is suitable for applications where the alternative packaging format is compatible with assembly equipment.

Equivalent Parts with Identical Core Ratings:

STPS1H100A and STPS1H100AY (STMicroelectronics) maintain the same 100V, 1A electrical specifications and 175°C maximum junction temperature as the main part. Both are supplied in Cut Tape (CT) & Digi-Reel® packaging. STPS1H100AY carries automotive-grade qualification (Series Q) and extended operating temperature range (-40°C to 175°C), making it suitable for automotive applications. Reverse leakage current is specified at 4µA compared to 1µA for the main part, which remains within acceptable limits for most applications.

Higher Current Capacity Alternatives:

STPS2H100A and STPS2H100AY are rated for 2A average rectified current while maintaining 100V reverse voltage and 175°C maximum junction temperature. These parts are suitable for applications requiring higher current capacity than the 1A specification of the main part. STPS2H100AY includes automotive-grade qualification. Both are supplied in Cut Tape (CT) & Digi-Reel® packaging.

Functional Equivalents with Parameter Variations:

B1100-13-F (Diodes Incorporated) meets the 100V, 1A core requirements but has a reduced maximum junction temperature of 150°C and higher reverse leakage current (500µA). Forward voltage is specified at 790mV compared to 770mV for the main part. This part is suitable for applications where the lower thermal rating is acceptable.

B190-13-F (Diodes Incorporated) is rated for 90V reverse voltage, which is below the 100V specification of the main part. This part is suitable only for applications where the circuit operates at 90V or lower. Maximum junction temperature is 150°C, and reverse leakage is 500µA.

CDBM1100-G (Comchip Technology) maintains 100V, 1A ratings but uses a different package format (SOD-123T/Mini SMA) requiring board layout modification. Maximum junction temperature is 150°C, and forward voltage is specified at 850mV. This part is suitable for space-constrained applications where the smaller package footprint is beneficial.

S100 (Fairchild Semiconductor) meets 100V, 1A requirements in DO-214AC (SMA) package but has a reduced maximum junction temperature of 125°C. This part is suitable for applications with lower thermal requirements.

SD2010S100S1R0 (KYOCERA AVX) provides 100V, 1A ratings in a 2-SMD, No Lead package format (2010/DO-214AC). Maximum junction temperature is 125°C. This part requires board layout verification due to package format differences.

Compliance and Regulatory Status:

All listed substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status, ensuring regulatory compatibility with the original SS1H10-E3/5AT specification.

Frequently Asked Questions (FAQ)

Q: Can SS1H10-E3/61T be used as a direct replacement for SS1H10-E3/5AT?

A: Yes. SS1H10-E3/61T is a parametric equivalent from Vishay with identical electrical specifications (100V, 1A, 770mV forward voltage, 1µA reverse leakage, 175°C maximum junction temperature). The only difference is packaging format: SS1H10-E3/61T is supplied in Cut Tape (CT) & Digi-Reel® instead of Tape & Reel (TR). Verify that your assembly equipment is compatible with the alternative packaging format.

Q: What is the difference between STPS1H100A and STPS1H100AY?

A: Both parts are electrically identical (100V, 1A, 770mV forward voltage, 4µA reverse leakage, 175°C maximum junction temperature) and use the same DO-214AC (SMA) package. STPS1H100AY carries automotive-grade qualification (Series Q) and an extended operating temperature range of -40°C to 175°C, compared to the standard industrial temperature range of STPS1H100A. Select STPS1H100AY for automotive applications requiring grade certification.

Q: Can STPS2H100A be used in place of SS1H10-E3/5AT?

A: STPS2H100A is electrically compatible for the 100V reverse voltage and 175°C maximum junction temperature specifications. However, STPS2H100A is rated for 2A average rectified current, which exceeds the 1A requirement of the main part. This higher current rating does not prevent substitution in 1A applications; the part will operate within its specifications. Verify that circuit design and thermal management are appropriate for the substitute part's characteristics.

Q: Why does B190-13-F have a lower reverse voltage rating than the main part?

A: B190-13-F is rated for 90V reverse voltage, which is 10V below the 100V specification of SS1H10-E3/5AT. This part is suitable only for applications where the circuit operates at 90V or lower. Do not use B190-13-F in circuits designed for 100V operation, as it will not meet the voltage margin requirements.

Q: What is the significance of reverse leakage current differences among substitute parts?

A: Reverse leakage current (Ir) represents the small current that flows through the diode when reverse biased. The main part specifies 1µA at 100V. Substitute parts vary: STPS1H100A/STPS1H100AY specify 4µA, B1100-13-F and CDBM1100-G specify 500µA, and S100/SD2010S100S1R0 specify 200µA. Higher reverse leakage increases power dissipation and heat generation. Select parts with reverse leakage specifications appropriate for your application's power budget and thermal constraints.

Q: Can CDBM1100-G be used as a direct replacement despite the different package?

A: CDBM1100-G uses a SOD-123T (Mini SMA) package instead of the DO-214AC (SMA) package of the main part. While electrically compatible (100V, 1A), the different package footprint requires board layout modification. The smaller package may be beneficial for space-constrained designs. Verify that your PCB layout and assembly process can accommodate the SOD-123T package before substitution.

Q: What is the impact of forward voltage differences on circuit performance?

A: Forward voltage (Vf) varies among substitute parts: the main part specifies 770mV at 1A, while some substitutes specify 790mV or 850mV. These differences affect voltage drop across the diode and power dissipation. In low-voltage circuits, higher forward voltage may impact performance. In high-voltage circuits (100V), the difference is typically negligible. Verify that your circuit design accommodates the forward voltage specification of the selected substitute part.

Q: Are all substitute parts suitable for automotive applications?

A: No. Only STPS1H100AY and STPS2H100AY carry automotive-grade qualification (Series Q). These parts are certified for automotive use with extended operating temperature ranges (-40°C to 175°C). Other substitute parts are industrial-grade components. Select automotive-qualified parts for applications requiring automotive certification or operating in automotive temperature environments.

Q: What packaging formats are available for the SS1H10-E3/5AT substitutes?

A: Substitute parts are available in the following packaging formats: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, SOD-123T (Mini SMA), and 2-SMD No Lead (2010/DO-214AC). The main part is supplied in Tape & Reel (TR). Cut Tape (CT) & Digi-Reel® format is compatible with most automated assembly equipment. Alternative package formats require verification of assembly process compatibility and PCB layout modifications.

Q: How do I select the appropriate substitute part for my application?

A: Identify the critical parameters for your application: required reverse voltage (minimum 100V for full compatibility), required current capacity (minimum 1A), thermal requirements (maximum junction temperature), and packaging constraints. Match these requirements to the substitute part specifications. For automotive applications, select parts with automotive-grade qualification. For space-constrained designs, consider parts with smaller package formats. Verify compliance and regulatory status for your end application.
