Product details
Overview
BZW04P23-E3/73 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 23.1 V standoff voltage (VWM), 37.5 V clamping voltage (VC) at 10.7 A peak pulse current, and 400 W peak pulse power capability with a 10/1000 µs waveform - ideal for safeguarding MOSFETs and sensor interfaces against inductive switching transients.
For engineers reviewing the BZW04P23-E3/73 datasheet, BZW04P23-E3/73 pinout, BZW04P23-E3/73 application, or BZW04P23-E3/73 equivalent, key selection considerations include its DO-41 package compatibility, AEC-Q101 qualification for automotive-grade reliability, bi-directional surge handling, low leakage (<1 µA at VWM), and temperature coefficient of breakdown voltage (0.096 %/°C).
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - eliminating polarity marking requirements on PCB layout. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while the 10/1000 µs surge rating reflects standardized IEC 61000-4-5 compliance testing conditions.
The device is rated for continuous power dissipation of 1.5 W on an infinite heatsink at 75 °C lead temperature and supports operating junction temperatures from –55 °C to +175 °C. Its 0.096 %/°C VBR temperature coefficient enables predictable clamping performance across automotive and industrial thermal environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | DO-214AA package; 24 V VWM, 38.9 V VC at 10.3 A; same 400 W rating but higher thermal resistance (RθJA ≈ 110 °C/W vs. DO-41's ~100 °C/W). | Preferred where board space allows SMC/SMB footprint and higher surge repetition rate is needed due to lower junction-to-case resistance. | Select SMBJ24CA when upgrading from through-hole to surface-mount and requiring tighter VWM/VC tolerance (±5 % vs. ±6.5 %). |
| P6KE27CA | DO-15 package; 27 V VWM, 43.5 V VC at 9.2 A; 600 W rating but larger body and higher VC - less effective clamping for 24 V systems. | Suitable for legacy designs with existing DO-15 footprints and where higher clamping voltage is acceptable for cost-sensitive industrial controls. | Choose P6KE27CA only if VC margin permits ≥43 V and board layout cannot accommodate DO-41 lead spacing. |
Compared with SMBJ24CA and P6KE27CA, BZW04P23-E3/73 offers optimal balance of compact DO-41 form factor, tight 23.1 V VWM, lowest clamping voltage (37.5 V), and AEC-Q101 qualification - making it the preferred choice for new automotive and high-reliability industrial designs where space and clamping performance are critical.

FAQ
What is the standoff voltage (VWM) of the BZW04P23-E3/73?
The BZW04P23-E3/73 has a maximum working standoff voltage (VWM) of 23.1 V, meaning it remains non-conductive up to this DC or RMS voltage level under normal operation. This value is confirmed in the Vishay datasheet (Document Number: 88316) and ensures compatibility with 24 V nominal systems while providing adequate margin against ripple and tolerance variation. The BZW04P23-E3/73 maintains <1 µA leakage at this voltage.
Is the BZW04P23-E3/73 bi-directional or uni-directional?
The BZW04P23-E3/73 is a bi-directional transient voltage suppressor, as indicated by the "B" suffix omission in its base part number and confirmed by Vishay's documentation stating that bi-directional types have no polarity marking. Its electrical characteristics - including VBR, VC, and IPPM - apply identically in both directions, enabling symmetric surge clamping on AC lines or differential signals without orientation constraints. The BZW04P23-E3/73 is functionally equivalent to BZW04P23B but supplied in commercial-grade E3 packaging.
Does the BZW04P23-E3/73 meet AEC-Q101 requirements?
Yes, the BZW04P23-E3/73 is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet under "MECHANICAL DATA" (HE3 suffix denotes AEC-Q101 qualification, and E3 suffix parts share the same die and process). This qualification validates its suitability for automotive applications including powertrain, chassis, and body electronics, covering stress tests for temperature cycling, humidity, mechanical shock, and accelerated life. The BZW04P23-E3/73 achieves full AEC-Q101 compliance while maintaining RoHS and JESD201 Class 1A whisker resistance.
What is the clamping voltage (VC) of the BZW04P23-E3/73 at its rated surge current?
The BZW04P23-E3/73 exhibits a maximum clamping voltage (VC) of 37.5 V when subjected to its rated 10.7 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per IEC 61000-4-5 test conditions and represents the upper voltage limit imposed on protected circuitry during surge events. The low VC relative to VWM ensures effective protection of 24 V-rated ICs and MOSFETs. The BZW04P23-E3/73 achieves this performance with minimal voltage overshoot due to its glass-passivated junction.
What package type does the BZW04P23-E3/73 use, and what are its key mechanical features?
The BZW04P23-E3/73 uses the DO-204AL (commonly known as DO-41) axial-leaded package, featuring molded epoxy encapsulation rated UL 94 V-0 for flame resistance. Its leads are matte tin-plated and solderable per J-STD-002 and JESD22-B102, with whisker resistance certified to JESD201 Class 1A. The package dimensions are standardized per Vishay's outline drawing: 25.4 mm minimum body length, 5.2 mm maximum diameter, and 0.66 mm lead diameter. The BZW04P23-E3/73 leverages this mature, cost-effective through-hole format while delivering automotive-grade reliability.
