SMCJ16CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMCJ16CE3/TR13 is a bidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This component operates with a 16V reverse standoff voltage and provides 28.8V maximum clamping voltage at peak pulse current of 52.1A, delivering 1500W peak pulse power dissipation. The device is packaged in DO-214AB (SMC) format on tape and reel for automated assembly.

The SMCJ16CE3/TR13 maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching electrical parameters—specifically reverse standoff voltage, breakdown voltage, clamping voltage, and package type—while accommodating variations in peak pulse current and power dissipation that remain within acceptable application ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMCJ16CE3/TR13 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage - Reverse Standoff (Typ): 16V
• Voltage - Breakdown (Min): 17.8V
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Type: Zener
• Bidirectional Channels: 1

Allowable Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: 26V to 28.8V (lower clamping voltage provides enhanced protection margin)
• Current - Peak Pulse (10/1000µs): 52.1A or higher (increased current handling capacity maintains or improves performance)
• Power - Peak Pulse: 1500W or higher (increased power dissipation capability)
• Operating Temperature Range: Must encompass or extend the original -65°C to 150°C range

All identified substitute parts maintain the same 16V reverse standoff voltage, 17.8V minimum breakdown voltage, and DO-214AB/SMC package format. Variations in clamping voltage (26V vs. 28.8V) and peak pulse current (57.7A to 193A) represent acceptable substitutions when application requirements permit lower clamping voltages or higher current ratings.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and full RoHS3 compliance, ensuring regulatory alignment with the original SMCJ16CE3/TR13 component. Selection among equivalent parts should be based on the following criteria:

Direct Electrical Equivalents (Recommended for Drop-In Replacement): SMCJ16CA (MDD), SMCJ16CA-13-F (Diodes Incorporated), and SMCJ16CA-TP (Micro Commercial Co) provide identical peak pulse current (57.7A) and power dissipation (1500W) specifications while maintaining the same 16V reverse standoff voltage and DO-214AB/SMC package. These parts differ only in clamping voltage (26V vs. 28.8V), which represents a 2.8V reduction in maximum clamp level. This variation is acceptable in applications where the lower clamping voltage provides adequate protection margins.

Enhanced Performance Alternatives: SMDJ16CA (Alpha & Omega Semiconductor Inc.) and SMLJ16CA (Bourns Inc.) offer doubled peak pulse current (115.4A) and power dissipation (3000W) while maintaining identical voltage parameters. These components are suitable for applications requiring higher transient energy absorption capacity.

Maximum Performance Option: 5.0SMDJ16CA (MDE Semiconductor Inc) delivers the highest peak pulse current (193A) and power dissipation (5000W) among all substitutes, providing the greatest margin for high-energy transient events.

Temperature Range Consideration: SMCJ16CA-TP extends the upper operating temperature limit to 175°C, compared to 150°C for the original part. This extended range is beneficial in high-temperature environments. Conversely, SMCJ16CA (MDD) operates from -50°C, which is 15°C warmer than the original -65°C minimum, and may not be suitable for cryogenic applications.

Supply Chain Availability: SMCJ16CA (MDD) maintains the highest inventory level (26,400 pcs), followed by SMLJ16CA (5,213 pcs) and 5.0SMDJ16CA (3,800 pcs), supporting rapid procurement requirements.

Regulatory Compliance: SMLJ16CA is designated as REACH Affected, whereas all other substitutes maintain REACH Unaffected status. Applications subject to REACH restrictions should prioritize alternatives with REACH Unaffected designation.

Frequently Asked Questions (FAQ)

Q: Can SMCJ16CA parts with 26V clamping voltage replace the SMCJ16CE3/TR13 with 28.8V clamping voltage?

A: Yes. The 26V clamping voltage represents a 2.8V reduction from the original 28.8V specification. This lower clamping voltage provides a tighter voltage clamp, which enhances transient suppression performance in most applications. Substitution is valid when the application circuit can tolerate the lower maximum clamp level without exceeding component or system voltage ratings.

Q: What is the difference between SMCJ16CA, SMDJ16CA, and SMLJ16CA?

A: These parts share identical voltage parameters (16V reverse standoff, 17.8V breakdown, 26V clamping) and package format (DO-214AB/SMC) but differ in peak pulse current and power dissipation ratings. SMCJ16CA handles 57.7A and 1500W, SMDJ16CA handles 115.4A and 3000W, and SMLJ16CA handles 115.4A and 3000W. Selection depends on the transient energy levels present in the application circuit.

Q: Are all substitute parts available in the same DO-214AB/SMC package?

A: Yes. All substitute parts are packaged in DO-214AB (SMC) format and are compatible with the same PCB footprint and automated assembly processes as the original SMCJ16CE3/TR13.

Q: Does the SMCJ16CA-TP operating temperature range of -55°C to 175°C make it superior to the original part?

A: The extended upper temperature limit of 175°C provides additional margin in high-temperature environments. However, the minimum operating temperature of -55°C is 10°C warmer than the original -65°C specification. For applications requiring operation below -55°C, the original SMCJ16CE3/TR13 or parts with equivalent lower temperature limits must be used.

Q: Why does 5.0SMDJ16CA have significantly higher peak pulse current (193A) and power (5000W)?

A: The 5.0SMDJ16CA is designed for higher-energy transient suppression applications. The increased current and power ratings allow this component to absorb larger transient events without degradation. It is suitable for applications with more severe overvoltage conditions or higher impedance transient sources.

Q: Is SMLJ16CA suitable for all applications where SMCJ16CE3/TR13 is used?

A: SMLJ16CA is electrically compatible and provides superior transient energy absorption (3000W vs. 1500W). However, SMLJ16CA carries REACH Affected status, whereas the original part is REACH Unaffected. Applications subject to REACH compliance requirements should confirm regulatory acceptability before substitution.

Q: Can I use SMCJ16CA (MDD) in place of SMCJ16CE3/TR13 in cryogenic applications?

A: No. SMCJ16CA (MDD) operates from -50°C minimum, which is 15°C warmer than the original -65°C specification. For cryogenic applications requiring -65°C operation, use SMCJ16CE3/TR13, SMCJ16CA-13-F, SMCJ16CA-TP, SMDJ16CA, SMLJ16CA, or 5.0SMDJ16CA, all of which support -55°C or lower minimum temperatures.

Q: What is the significance of the 1500W power rating in the original SMCJ16CE3/TR13?

A: The 1500W peak pulse power rating indicates the maximum energy the component can dissipate during a 10/1000µs transient pulse without exceeding thermal limits. Applications with transient energy levels exceeding this rating require substitution with higher-power alternatives such as SMDJ16CA (3000W) or 5.0SMDJ16CA (5000W).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain full RoHS3 compliance, ensuring compatibility with RoHS-regulated supply chains and end-use applications.
