Substitute Part Grouping Explanation

Substitute parts for the SMBJ26CA-M3/5B are qualified based on the following electrical and mechanical criteria:

Voltage - Reverse Standoff (Typ): 26V
Voltage - Breakdown (Min): 28.9V
Voltage - Clamping (Max) @ Ipp: 42.1V
Current - Peak Pulse (10/1000µs): 14.2A to 14.9A (within tolerance band)
Power - Peak Pulse: 600W
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Bidirectional Channels: 1
Type: Zener
RoHS Status: ROHS3 Compliant
MSL Rating: 1 (Unlimited)

Parts meeting these criteria are electrically and mechanically interchangeable. Variations in peak pulse current within the specified range do not affect circuit compatibility for general-purpose transient suppression applications.

Engineering Selection Recommendations

All listed substitute parts maintain identical electrical specifications for voltage clamping, breakdown voltage, and power dissipation. Selection among qualified substitutes should be based on:

Product availability and inventory levels
Manufacturer certification status (all parts are RoHS3 compliant and MSL 1 rated)
Operating temperature requirements (SMBJ26CA from EVVO Semi extends to -65°C; SMBJ26CA-TP from Micro Commercial Co extends to 175°C)
Peak pulse current tolerance (all parts operate within 14.2A to 14.9A range)
Packaging format and supplier logistics

All substitute parts are Active status products suitable for new designs and production applications.

Frequently Asked Questions (FAQ)

Q: Can SMBJ26CA-E3/52 replace SMBJ26CA-M3/5B directly?

A: Yes. Both parts are manufactured by Vishay with identical electrical parameters (26V standoff, 42.1V clamping, 14.3A peak pulse), same package (DO-214AA, SMB), and equivalent compliance ratings. The difference is in packaging format and inventory availability.

Q: What is the difference between SMBJ26CA from EVVO Semi and the Vishay variants?

A: The EVVO Semi SMBJ26CA maintains all critical electrical parameters but extends the operating temperature range to -65°C (versus -55°C for Vishay). This provides additional thermal margin for low-temperature applications while maintaining the same clamping and breakdown characteristics.

Q: Is SMBJ26CA-TP from Micro Commercial Co compatible with the original specification?

A: Yes. The SMBJ26CA-TP meets all electrical requirements with 14.2A peak pulse current and extends the upper operating temperature to 175°C. This variant is suitable for applications requiring higher temperature operation while maintaining the 26V/42.1V voltage characteristics.

Q: How does peak pulse current variation (14.2A to 14.9A) affect substitution?

A: All variants operate within the transient voltage suppression specification for 26V devices. The variation reflects manufacturing tolerance bands across different manufacturers and does not affect circuit compatibility for general-purpose transient suppression.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity rating, meeting the same environmental and regulatory requirements as the original SMBJ26CA-M3/5B.

Q: What packaging formats are available?

A: All substitute parts use DO-214AA (SMB) surface mount package. Packaging options vary by supplier (Tape & Reel or Cut Tape & Digi-Reel), but the physical component package remains identical for PCB assembly compatibility.
