P6SMB100CA-M3/52 Equivalent & Substitute Parts

Part Overview

The P6SMB100CA-M3/52 is a bidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 85.5V reverse standoff voltage range with a 137V maximum clamping voltage and 4.4A peak pulse current rating. The device is designed for general-purpose transient voltage suppression applications and is currently in active production status. Equivalent and substitute parts are identified when they maintain the same electrical performance envelope and mechanical compatibility within the DO-214AA (SMB) package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB100CA-M3/52 are qualified based on the following criteria:

Electrical Parameters (Primary):

• Voltage - Reverse Standoff (Typ): 85.5V
• Voltage - Breakdown (Min): 95V minimum
• Package / Case: DO-214AA, SMB (mechanical compatibility)
• Bidirectional Channels: 1
• Type: Zener TVS diode
• Applications: General Purpose

Compliance & Certification (Secondary):

• RoHS3 Compliant status
• Moisture Sensitivity Level (MSL): 1
• REACH Unaffected status
• Product Status: Active

Substitutes may vary in clamping voltage and peak pulse current specifications while maintaining the core voltage suppression function within the same package footprint. Operating temperature range variations are acceptable provided the minimum operating temperature does not exceed -55°C and maximum does not fall below 150°C.

Parameter Comparison

Engineering Selection Recommendations

P6SMB100CA (Good-Ark Semiconductor): This substitute maintains identical electrical specifications to the P6SMB100CA-M3/52, including voltage ratings, clamping characteristics, and peak pulse current. Both devices are ROHS3 compliant with MSL 1 rating and active production status. The primary difference is packaging format (Tape & Reel versus Tape & Box) and operating temperature lower limit (-55°C versus -65°C). This substitute is suitable for applications where the -55°C minimum temperature is acceptable.

SM6T100CA (STMicroelectronics): This substitute shares the same reverse standoff voltage (85.5V) and breakdown voltage (95V) as the primary part, ensuring equivalent voltage suppression initiation. However, the clamping voltage is higher at 178V with significantly increased peak pulse current capability (22.5A at 8/20µs pulse width versus 4.4A at 10/1000µs). This device is ROHS3 compliant with MSL 1 rating and active production status. The SM6T100CA is suitable for applications requiring higher transient current handling or where the higher clamping voltage is within system tolerance.

Frequently Asked Questions (FAQ)

Q: Can P6SMB100CA (Good-Ark) be used as a direct replacement for P6SMB100CA-M3/52?

A: Yes, the P6SMB100CA from Good-Ark Semiconductor provides identical electrical performance with the same voltage ratings, clamping characteristics, and peak pulse current. Both are ROHS3 compliant with MSL 1 rating. The operating temperature lower limit differs (-55°C versus -65°C), which should be verified against application requirements.

Q: What are the key differences between SM6T100CA and the primary part?

A: The SM6T100CA maintains the same reverse standoff and breakdown voltages but features a higher clamping voltage (178V versus 137V) and significantly higher peak pulse current capability (22.5A versus 4.4A). Both are in the same DO-214AA SMB package. Selection depends on whether the application requires the higher current handling or can tolerate the increased clamping voltage.

Q: Are all substitute parts in the same package?

A: Yes, all listed substitutes use the DO-214AA (SMB) package, ensuring mechanical and footprint compatibility with the P6SMB100CA-M3/52.

Q: Do all substitutes meet the same compliance standards?

A: All substitutes are ROHS3 compliant, REACH unaffected, and have MSL 1 (Unlimited) moisture sensitivity rating. All are in active production status.

Q: What should determine my choice between substitutes?

A: Selection should be based on: (1) operating temperature requirements, particularly the lower temperature limit; (2) transient current magnitude in the application; (3) acceptable clamping voltage range; (4) component availability and lead time; (5) supply chain and cost considerations.
