Engineering Selection Recommendations

Direct Substitutes (Electrically and Mechanically Identical):

SMBJ36A-E3/52, SMBJ36A-M3/52, SMBJ36A-13-F, SMBJ36A-TP, and EVVO Semi SMBJ36A are direct functional equivalents. These parts maintain identical reverse standoff voltage (36V), clamping voltage (58.1V), and peak pulse current (10.3A to 10.4A). All are RoHS3 compliant with Active product status. Selection among these is based on packaging format availability (Tape & Reel vs. Cut Tape) and inventory requirements. SMBJ36A-TP offers extended operating temperature to 175°C.

Acceptable Alternatives with Minor Parameter Variations:

SMBJ36D-M3/I (Vishay) presents a minor clamping voltage variation (57.3V vs. 58.1V) and slightly higher peak pulse current (10.5A vs. 10.3A). This part remains within functional tolerance for general-purpose transient protection and maintains identical reverse standoff voltage and power rating.

SACB36 (Littelfuse) and SM6T36A (STMicroelectronics) are manufacturer-recommended alternatives with notable parameter differences. SACB36 reduces peak pulse current to 8.6A and power to 500W while maintaining 36V reverse standoff. SM6T36A operates at a lower reverse standoff voltage (30.8V) with significantly higher peak pulse current (62A at 8/20µs pulse width) and different clamping characteristics. These alternatives are suitable only for applications where the parameter variations are acceptable.

All recommended substitutes maintain RoHS3 compliance and Active product status, ensuring regulatory alignment and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can SMBJ36A-E3/52 replace SMBJ36A-E3/5B directly?

A: Yes. Both parts are manufactured by Vishay with identical electrical specifications (36V reverse standoff, 58.1V clamping voltage, 10.3A peak pulse current, 600W power). The difference is packaging format: E3/5B uses Tape & Reel while E3/52 uses Cut Tape & Digi-Reel. Electrical performance and mechanical fit are identical.

Q: What is the difference between SMBJ36A-M3/52 and SMBJ36A-E3/5B?

A: Both are Vishay TransZorb® devices with identical electrical parameters. The designation difference (E3 vs. M3) reflects internal manufacturing or qualification variations, but electrical and mechanical specifications remain equivalent. Both use Tape & Reel packaging and are suitable for direct substitution.

Q: Is SMBJ36D-M3/I a suitable replacement?

A: SMBJ36D-M3/I is functionally compatible with minor variations. The clamping voltage is 57.3V (vs. 58.1V) and peak pulse current is 10.5A (vs. 10.3A). The reverse standoff voltage remains 36V. This part is acceptable for applications where these parameter variations fall within design tolerance.

Q: Can I use EVVO Semi SMBJ36A instead of the Vishay part?

A: EVVO Semi SMBJ36A matches the electrical specifications (36V reverse standoff, 58.1V clamping, 10.4A peak pulse current). However, the package designation differs: EVVO uses DO-214AC (SMA) while Vishay uses DO-214AA (SMB). Verify PCB footprint compatibility before substitution. Operating temperature range extends to -65°C.

Q: What are the limitations of SACB36 as a substitute?

A: SACB36 (Littelfuse) maintains 36V reverse standoff voltage but reduces peak pulse current to 8.6A and power rating to 500W (vs. 10.3A and 600W). Use SACB36 only in applications where lower current handling is acceptable. Clamping voltage increases to 60V.

Q: Is SM6T36A compatible with SMBJ36A-E3/5B?

A: SM6T36A (STMicroelectronics) has significant parameter differences. Reverse standoff voltage is lower (30.8V vs. 36V), peak pulse current is much higher (62A at 8/20µs vs. 10.3A at 10/1000µs), and clamping voltage is higher (64.3V). This part is not a direct substitute and is suitable only for applications with different voltage and current requirements.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All listed substitutes maintain MSL 1 (Unlimited), indicating no moisture sensitivity concerns for storage and handling.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant, ensuring regulatory alignment with current environmental standards.

Q: What packaging formats are available?

A: Substitutes are available in Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats. Both formats contain identical components; selection depends on assembly line requirements and inventory management preferences.
