Best Alternatives to H15VND3B

Package: SOD-323Zhuhai Hongjiacheng Technology Co., Ltd.TVS - DiodesReverse Working Voltage (VRWM): 15 VBreakdown Voltage (VBR): 16 V - 20 VClamping Voltage (VC): 24 V - 38 VPeak Pulse Power (PPP): 304 WPeak Pulse Current (IPP): 8 A

H15VND3B is a 15V bi-directional TVS diode in a SOD-323 package for ESD protection. When searching for a replacement, key parameters are the 15V working voltage, bi-directional polarity, and peak current rating of 8A.

AI replacement insight

Electrical riskmedium

Capacitance and clamping voltage differences require review.

Package risklow

SOD-323 is a standard package with many options.

Sourcing risklow

Multiple viable alternatives exist from different manufacturers.

Can it be replaced directly?

Direct replacement for H15VND3B should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

PSD15C-ES offers an upgrade in power handling with minimal parametric changes, making it the most promising path.

Main risk

The main risks are incorrect polarity (using a uni-directional part) or increased junction capacitance impacting signal integrity.
