Product details
Overview
BZW04P10BHE3/73 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection in signal and power lines. It features a 10.2 V stand-off voltage (VWM), 16.7 V maximum clamping voltage (VC) at 24.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the BZW04P10BHE3/73 datasheet, BZW04P10BHE3/73 pinout, BZW04P10BHE3/73 application, or BZW04P10BHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AL (DO-41) axial package, bi-directional symmetry, low 0.078 %/°C VBR temperature coefficient, and suitability for inductive switching surge suppression without polarity constraints.
Technical Context
This bi-directional TVS operates symmetrically in both forward and reverse bias, delivering consistent clamping performance across polarity. Its glass-passivated junction ensures stable breakdown behavior under repetitive transients, while the 10/1000 µs waveform rating reflects standardized surge immunity per ANSI/IEEE C62.35.
The device is rated for 175 °C maximum junction temperature and exhibits low incremental surge resistance - critical for minimizing let-through energy during ESD or lightning-induced surges. Its 1.0 mA test current (IT) and 1.0 µA max reverse leakage (ID) at VWM support precise threshold control in low-power sensing circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | DO-214AA package (SMB), 10 V VWM, 17.0 V VC at 24.3 A; same 400 W PPPM but higher capacitance (~150 pF vs. ~50 pF). | Higher junction capacitance may affect high-speed signal integrity; better suited for power rail vs. data line protection. | Choose SMBJ10CA for space-constrained PCBs where surface-mount is mandatory and signal bandwidth <1 MHz. |
| P6KE10CA | DO-15 package, 10 V VWM, 17.0 V VC at 23.3 A; identical electrical specs but not AEC-Q101 qualified and higher leakage (5.0 µA). | Lacks automotive qualification and has looser leakage spec - unsuitable for battery-powered or safety-critical nodes. | Select P6KE10CA only for cost-sensitive commercial-grade applications where AEC-Q101 and ultra-low ID are not required. |
Compared with BZW04P10BHE3/73, SMBJ10CA offers SMT compatibility at the expense of higher parasitic capacitance, while P6KE10CA sacrifices automotive reliability and leakage performance for lower unit cost - making BZW04P10BHE3/73 the optimal choice for AEC-Q101–mandated, low-leakage, through-hole designs.
