Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the STB15100C are qualified based on the following criteria:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 100 V
• Mounting Type: Surface Mount
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• RoHS Status: RoHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Current - Average Rectified (Io) (per Diode): May vary based on application requirements
• Voltage - Forward (Vf) (Max) @ If: Acceptable within typical Schottky forward voltage range
• Current - Reverse Leakage @ Vr: Acceptable within specified operating conditions
• Operating Temperature - Junction: May extend beyond -55°C ~ 150°C range
• Manufacturer: Different qualified sources permitted
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® acceptable

All substitute parts listed maintain electrical compatibility through identical reverse voltage rating, diode configuration, and package form factor. Differences in forward voltage and reverse leakage are within acceptable tolerances for Schottky diode array applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and RoHS3 compliance, ensuring continued availability and regulatory conformance. Selection among substitute parts should be based on the following factors:

CSHDD16-100C TR13 PBFREE (Central Semiconductor Corp): Offers extended operating temperature range (-65°C ~ 175°C) and higher current rating (16A). Suitable for applications requiring enhanced thermal performance. REACH Unaffected status provides regulatory advantage in certain markets.

MBRB10100CT (SMC Diode Solutions): Maintains identical manufacturer as primary part with same operating temperature range (-55°C ~ 150°C). Forward voltage specification (850 mV @ 5 A) closely aligns with STB15100C. REACH Affected status matches primary part.

MBRB20100CT-13 (Diodes Incorporated): Qualified to AEC-Q101 automotive standard with 10A current rating and extended temperature range (-55°C ~ 175°C). Highest inventory availability (33,400 pcs). REACH Unaffected status. Suitable for automotive and industrial applications.

MBRS20100CTH (Taiwan Semiconductor Corporation): Qualified to AEC-Q101 automotive standard with highest current rating (20A) and extended temperature capability. REACH Unaffected status. Appropriate for high-current applications within automotive grade requirements.

STPS10H100CG-TR (STMicroelectronics): Lowest reverse leakage current (3.5 µA @ 100 V) and forward voltage (730 mV @ 5 A) specifications. 5A current rating. REACH Unaffected status. Optimal for low-leakage applications.

Frequently Asked Questions (FAQ)

Q: Can CSHDD16-100C TR13 PBFREE be used as a direct replacement for STB15100C?

A: Yes. Both parts share identical diode configuration (1 Pair Common Cathode), Schottky technology, 100 V reverse voltage rating, TO-263-3 D2PAK package, and fast recovery speed specifications. The CSHDD16-100C provides extended operating temperature range (-65°C ~ 175°C versus -55°C ~ 150°C) and higher current capability (16A), making it suitable for applications within the STB15100C's electrical envelope.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Both packaging formats contain identical components in the same TO-263-3 D2PAK package. Tape & Reel (TR) provides continuous reel format for automated assembly lines. Cut Tape (CT) & Digi-Reel® offers flexibility for lower-volume production or mixed component orders. Electrical and mechanical specifications remain unchanged between packaging formats.

Q: Are automotive-qualified parts (AEC-Q101) compatible with non-automotive applications?

A: Yes. AEC-Q101 qualification indicates enhanced reliability testing and quality assurance. Parts meeting automotive standards (MBRB20100CT-13 and MBRS20100CTH) are fully compatible with general industrial and consumer applications. The qualification represents a superset of standard requirements.

Q: How do forward voltage differences affect circuit performance?

A: Forward voltage specifications are provided at specific test currents. The STB15100C specifies 750 mV @ 7.5 A. Substitute parts with different forward voltage ratings (ranging from 730 mV to 1.1 V) operate within acceptable Schottky diode characteristics. Selection should consider the specific current level at which the diode operates in the application circuit.

Q: What does REACH Affected versus REACH Unaffected status indicate?

A: REACH Affected status indicates the part contains substances of concern requiring compliance documentation. REACH Unaffected status indicates the part does not contain restricted substances under current REACH regulations. Both statuses are compliant; selection depends on customer supply chain requirements and regional regulations.

Q: Can parts with different reverse leakage current ratings be substituted?

A: Yes. Reverse leakage current specifications (ranging from 3.5 µA to 1 mA @ 100 V) represent normal variation within Schottky diode technology. Selection should consider application sensitivity to leakage current. Applications with strict leakage requirements should select STPS10H100CG-TR (3.5 µA) or CSHDD16-100C (50 µA).

Q: Is the D2PAK package identical across all listed parts?

A: Yes. All substitute parts use TO-263-3, D2PAK (2 Leads + Tab), TO-263AB package configuration. This ensures mechanical and thermal compatibility with existing PCB layouts and thermal management designs. Pin configuration and lead spacing are identical across all listed parts.

Q: What inventory considerations apply to substitute selection?

A: Current inventory levels vary significantly among substitute parts. MBRB20100CT-13 offers highest availability (33,400 pcs), while MBRS20100CTH offers lowest (2,534 pcs). Inventory status should be verified at time of procurement, as availability changes based on market demand and manufacturing schedules.
