What risks should I check before replacing PESD2CAN,215?

Before replacing, verify three key things: 1) The pinout of the SOT-23 package matches your board layout. 2) The clamping voltage and capacitance of the replacement are within your system's tolerance. 3) For cross-vendor parts, confirm the supplier's reliability.

PESD2CAN,215 Alternatives, Datasheet & Cross Reference | Nexperia USA Inc.

PESD2CAN,215 is a 24V bidirectional TVS diode for CAN bus protection, now marked as 'Not For New Designs'. Fortunately, strong, active upgrades like the onsemi SZNUP2105LT1G are available.

AI replacement insight

Electrical risklow

Key specs are matched or improved. Clamping voltage and capacitance are close and should be verified.

Package risklow

SOT-23 package is a match, but pinout must be confirmed via datasheet.

Sourcing risklow

The primary upgrade path (onsemi) is a major, reliable manufacturer.

Can it be replaced directly?

Yes, there are strong candidates to replace PESD2CAN,215. SZNUP2105LT1G is an excellent upgrade, and PESD2CAN from GOODWORK is a functional alternative, though both require pinout verification.

Best replacement path

The SZNUP2105LT1G from onsemi is the best replacement path. It is an active part, AEC-Q101 qualified, and offers superior electrical characteristics in the same package.

Main risk

The primary risk is ensuring the pinout of the SOT-23 package is identical. While standardized, variations exist. A secondary risk involves minor differences in dynamic electrical properties like clamping voltage and capacitance.

Recommended alternatives

An active, AEC-Q101 qualified CAN bus protector from onsemi with higher power and current ratings in the same SOT-23 package.
