Part Overview

The SMCJ100CE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This bidirectional zener diode operates with a 100V reverse standoff voltage and provides clamping at 179V maximum, with a peak pulse current rating of 8.4A and peak pulse power of 1500W. The device is housed in a DO-214AB (SMC) package and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

The SMCJ100CE3/TR13 is an active product. Equivalent and substitute parts are identified based on matching core electrical parameters: reverse standoff voltage (100V), breakdown voltage range (111V minimum), bidirectional channel configuration (1 channel), surface-mount packaging (DO-214AB/SMC), and general-purpose application classification. Substitutes may vary in clamping voltage, peak pulse current, and peak pulse power ratings within acceptable operational ranges.

Engineering Selection Recommendations

All substitute parts listed are active products with RoHS3 compliance and REACH unaffected or REACH affected status, meeting current regulatory requirements. Selection among equivalent parts depends on application-specific requirements:

Direct Electrical Equivalents (Matched Power Dissipation):

SMCJ100CA (HY Electronic) and SMCJ100CA-13-F (Diodes Incorporated) provide identical electrical performance to the SMCJ100CE3/TR13 with 1500W peak pulse power and 9.3A peak pulse current. These are suitable for applications with identical power budget constraints.

Enhanced Performance Alternatives (Higher Power Dissipation):

SMDJ100CA (Alpha & Omega Semiconductor) and SMDJ100CA-T7 (Littelfuse) offer 3000W peak pulse power with 18.6A and 18.5A peak pulse current respectively, providing increased transient energy absorption capability while maintaining the same reverse standoff and breakdown voltages.
SMLJ100CA (Bourns) delivers 3000W peak pulse power with 18.6A peak pulse current in a Digi-Reel packaging option.

Maximum Performance Alternative:

5.0SMDJ100CA (MDE Semiconductor) provides the highest power dissipation at 5000W with 30.9A peak pulse current, suitable for applications requiring maximum transient protection margin.

Temperature Range Consideration:

SMCJ100CE3/TR13 and SMDJ100CA-T7 (Littelfuse) support the extended operating temperature range of -65°C to 150°C. All other substitutes operate from -55°C to 150°C.

All substitute parts maintain the DO-214AB/SMC surface-mount package format and are compatible with existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SMCJ100CA substitute for SMCJ100CE3/TR13?

A: Yes. SMCJ100CA (HY Electronic) and SMCJ100CA-13-F (Diodes Incorporated) are direct electrical equivalents with identical reverse standoff voltage (100V), breakdown voltage (111V minimum), clamping voltage (162V), peak pulse current (9.3A), and peak pulse power (1500W). Both are RoHS3 compliant and use the same DO-214AB/SMC package. The primary difference is manufacturer and packaging format.

Q: What is the difference between SMCJ100CE3/TR13 and SMDJ100CA?

A: Both devices share the same 100V reverse standoff voltage, 111V breakdown voltage, and 162V clamping voltage. The SMDJ100CA provides higher peak pulse current (18.6A versus 8.4A) and peak pulse power (3000W versus 1500W). The SMDJ100CA is suitable for applications requiring greater transient energy absorption. Operating temperature ranges differ: SMCJ100CE3/TR13 operates from -65°C to 150°C, while SMDJ100CA operates from -55°C to 150°C.

Q: Is 5.0SMDJ100CA compatible with SMCJ100CE3/TR13?

A: Yes, from an electrical standpoint. Both devices have 100V reverse standoff voltage and 111V breakdown voltage. The 5.0SMDJ100CA provides significantly higher peak pulse current (30.9A) and peak pulse power (5000W), making it suitable for higher-energy transient events. Both use the DO-214AB/SMC package and are RoHS3 compliant. The 5.0SMDJ100CA operates from -55°C to 150°C, compared to -65°C to 150°C for the SMCJ100CE3/TR13.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts use the DO-214AB or SMC package designation, which are equivalent surface-mount packages. This ensures compatibility with existing PCB layouts and assembly equipment. Packaging format variations (Tape & Reel, Cut Tape, Digi-Reel) affect handling and supply chain logistics but do not affect electrical performance or physical footprint.

Q: What is the significance of clamping voltage differences?

A: Clamping voltage determines the maximum voltage level the TVS diode allows across the protected circuit during a transient event. The SMCJ100CE3/TR13 clamps at 179V maximum, while most substitutes clamp at 162V. Lower clamping voltage provides tighter protection but may require verification that the protected circuit can tolerate the clamping level. Higher clamping voltage allows higher transient voltages to pass through before suppression occurs.

Q: Which substitute offers the best thermal performance?

A: The 5.0SMDJ100CA (MDE Semiconductor) offers the highest peak pulse power rating at 5000W, indicating superior thermal dissipation capability during transient events. The SMDJ100CA and SMLJ100CA both provide 3000W peak pulse power. The SMCJ100CA variants provide 1500W, matching the original SMCJ100CE3/TR13.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant. REACH status varies: SMCJ100CE3/TR13, SMCJ100CA-13-F, SMDJ100CA, SMDJ100CA-T7, and 5.0SMDJ100CA are REACH unaffected. SMLJ100CA is REACH affected. HY Electronic SMCJ100CA variants show vendor undefined REACH status.

Q: Can I use a substitute with lower peak pulse current?

A: No. Substitutes must have equal or greater peak pulse current rating than the original part. Using a device with lower peak pulse current may result in inadequate transient suppression and potential circuit damage. All listed substitutes meet or exceed the 8.4A peak pulse current of the SMCJ100CE3/TR13.

Q: What is the impact of operating temperature range differences?

A: The SMCJ100CE3/TR13 and SMDJ100CA-T7 support -65°C to 150°C operation. Other substitutes support -55°C to 150°C. If your application requires operation below -55°C, only these two devices are suitable. For applications within -55°C to 150°C, all substitutes are acceptable.
