Product details
Overview
BZW04-23BHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of signal and power lines. It features a 23.1 V stand-off voltage (VWM), 25.7–28.4 V breakdown voltage (VBR) at 1 mA, 37.5 V clamping voltage (VC) at 10.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the BZW04-23BHE3/54 datasheet, BZW04-23BHE3/54 pinout, BZW04-23BHE3/54 application, or BZW04-23BHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical data, thermal derating curves, and direct alternative part comparisons for ESD/surge co-design.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR, VC, and IPPM specifications across forward and reverse directions. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and low incremental surge resistance, critical for fast transient suppression on high-impedance nodes.
The device is rated for 175 °C maximum junction temperature and supports soldering per JESD 22-B106 (275 °C, 10 s). The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - essential for automotive under-hood and body electronics applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 23.1 V - Maximum continuous working voltage before clamping begins; defines safe operating margin for 24 V nominal systems. |
| VBR (min/max) | 25.7 V / 28.4 V at 1 mA - Tight breakdown tolerance ensures predictable turn-on during transients without premature conduction. |
| VC @ IPPM | 37.5 V at 10.7 A - Clamping voltage limits downstream IC stress during 400 W surge events; enables reliable protection of 30 V-rated components. |
| PPPM | 400 W - Peak pulse power handling with 10/1000 μs waveform; supports IEC 61000-4-5 Level 3 (1 kV/2 Ω) surge immunity. |
| IPPM | 10.7 A - Peak pulse current capability derived from 400 W / 37.5 V; determines minimum series impedance required for compliance. |
| TJ max. | 175 °C - Enables operation in under-hood automotive environments and industrial enclosures without thermal derating penalties below 125 °C ambient. |
| Leakage @ VWM | <1.0 μA - Minimal standby power loss and negligible loading on high-impedance sensor bias networks. |
Pinout & Package
DO-41 (DO-204AL) axial-leaded package with matte tin-plated leads; no polarity marking for bidirectional configuration - terminals are functionally symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Identical bidirectional clamping behavior; either lead may connect to protected line or ground - no orientation dependency. |
| Lead 1 / Lead 2 | Thermal and mechanical interface | Leads serve as primary heat dissipation path; 0.028–0.034 inch diameter supports 1.5 W steady-state dissipation with proper PCB copper area. |
Key Features

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 @ 10.3 A; same 400 W rating but higher junction capacitance (~150 pF). | Surface-mount footprint requires PCB redesign; better suited for high-density consumer boards than through-hole automotive harnesses. | Select when space-constrained layouts demand SMD integration and thermal management via copper pour is feasible. |
| 1.5KE24CA | DO-201AD package; 24 V VWM; 38.5 V VC @ 10.4 A; 1500 W peak rating but slower response due to larger junction area. | Higher energy handling suits infrequent high-energy surges (e.g., AC mains); less optimal for repetitive fast transients in data lines. | Choose for cost-sensitive industrial power supply protection where surge frequency is low and board space allows axial-leaded devices. |
Compared with SMBJ24CA and 1.5KE24CA, BZW04-23BHE3/54 offers AEC-Q101 qualification, lower leakage (<1.0 μA), tighter VBR tolerance (±5%), and optimized response for automotive-grade bidirectional signal line protection in DO-41 through-hole format.

FAQ
What is the clamping voltage of BZW04-23BHE3/54 and how does it protect downstream circuits?
The BZW04-23BHE3/54 has a maximum clamping voltage (VC) of 37.5 V at 10.7 A peak pulse current. This value defines the upper voltage limit imposed on protected circuitry during a transient event. By limiting voltage excursions to ≤37.5 V, the BZW04-23BHE3/54 prevents damage to 30 V-rated ICs such as CAN transceivers and microcontrollers, ensuring system-level surge immunity per IEC 61000-4-5.
Is BZW04-23BHE3/54 suitable for automotive applications?
Yes, BZW04-23BHE3/54 is AEC-Q101 qualified (HE3 suffix), tested for temperature cycling, humidity, mechanical shock, and surge endurance under automotive conditions. Its 175 °C maximum junction temperature, low leakage (<1.0 μA), and bidirectional symmetry make it appropriate for engine control units, body electronics, and ADAS sensor interfaces where reliability across -40 °C to +125 °C ambient is required.
How does the DO-41 package of BZW04-23BHE3/54 affect thermal performance?
The DO-41 (DO-204AL) axial package of BZW04-23BHE3/54 provides 1.5 W power dissipation on an infinite heatsink at 75 °C lead temperature. In practice, thermal performance depends on PCB copper area and lead length; ≥100 mm² of 2 oz copper per lead reduces thermal resistance by ~20 °C/W. The 0.028–0.034 inch lead diameter supports manual or wave soldering per JESD 22-B106.
What is the difference between BZW04-23BHE3/54 and BZW04-23HE3/54?
BZW04-23BHE3/54 is bidirectional (denoted by "B" suffix), providing symmetrical clamping in both polarities - ideal for AC signal lines and differential buses. BZW04-23HE3/54 is unidirectional, with a cathode band marking and forward conduction only; it would require correct orientation and cannot protect negative-going transients without additional components. Both share identical VWM, VBR, and PPPM ratings.
Does BZW04-23BHE3/54 require external current-limiting components?
Yes, BZW04-23BHE3/54 must be used with a series impedance (e.g., resistor or PTC) to limit peak current during clamping and prevent thermal runaway. For a 400 W surge at 37.5 V, minimum recommended series resistance is ~3.5 Ω to keep IPPM within 10.7 A. The exact value depends on source impedance and system-level surge profile defined in standards like ISO 7637-2 or IEC 61000-4-5.
