Product details
Overview
BZW04-23HE3/54 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 standoff voltage (VWM), 25.7–28.4 V breakdown range (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 BZW04-23HE3/54 datasheet, BZW04-23HE3/54 pinout, BZW04-23HE3/54 application, or BZW04-23HE3/54 equivalent, this device delivers AEC-Q101 qualified transient suppression for bidirectional signal lines where low leakage (<1 μA at VWM), fast response (<1 ns), and stable temperature coefficient (0.096 %/°C) are critical to system reliability under ESD and load-switching surges.
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 low incremental surge resistance and excellent clamping consistency during repetitive 10/1000 μs transients at 0.01% duty cycle.
The device is rated for continuous power dissipation of 1.5 W on an infinite heatsink at 75 °C and supports operating junction temperatures from –55 °C to +175 °C. It meets JESD22-B102 solderability standards and JESD201 class 2 whisker resistance (HE3 suffix), confirming suitability for high-reliability automotive PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 23.1 V - Maximum continuous reverse working voltage before conduction begins; sets safe operating margin below system rail. |
| VBR (min/max) | 25.7 V / 28.4 V at 1 mA - Confirmed breakdown threshold range ensuring predictable turn-on during transients. |
| VC @ IPPM | 37.5 V at 10.7 A - Clamped voltage during 400 W surge; defines maximum stress imposed on protected IC inputs. |
| IPPM | 10.7 A - Peak pulse current capability with 10/1000 μs waveform; determines survivability against IEC 61000-4-5 Level 3 surges. |
| PPPM | 400 W - Peak pulse power handling; enables protection of 24 V industrial control lines against inductive switching spikes. |
| TJ max | +175 °C - Maximum junction temperature; supports operation in under-hood automotive environments and sealed enclosures. |
| Leakage @ VWM | <1 μA - Ultra-low reverse leakage preserves signal integrity and battery life in always-on sensor circuits. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; no polarity marking for bidirectional configuration - both terminals are electrically symmetrical. Matte tin-plated leads meet J-STD-002 solderability and JESD201 class 2 whisker resistance requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional transient conduction path | No cathode band; either lead serves as input/output - simplifies layout and eliminates orientation errors in PCB placement. |
| Lead 1 | Transient current entry point | Carries full IPPM surge current during positive or negative transients; requires ≥0.375" (9.5 mm) lead length for thermal derating compliance. |
| Lead 2 | Transient current return path | Completes low-inductance surge path to ground or rail; symmetry enables direct series insertion into differential or single-ended lines. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control modules and ADAS sensor interfaces per stress test requirements. |
| Glass-passivated junction | Enables stable VBR tolerance and low dynamic resistance (<0.5 Ω typical) for repeatable clamping performance over lifetime. |
| 400 W peak pulse power | Supports protection against ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Combination Wave surges without degradation. |
| UL 94 V-0 molding compound | Ensures flame-retardant enclosure integrity in safety-critical industrial and transportation equipment. |

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; 600 W PPPM; higher capacitance (~150 pF) | Preferred for surface-mount designs with space constraints; less suitable for through-hole legacy boards or high-frequency analog lines. | Select SMBJ24CA when board real estate is limited and higher surge rating justifies rework for SMD placement. |
| 1.5KE24CA | DO-201AD package; 24 V VWM, 38.9 V VC @ 10.3 A; 1500 W PPPM; larger footprint and higher leakage (≤5 μA) | Used in high-energy industrial power supplies where physical size is secondary to surge margin and thermal mass. | Choose 1.5KE24CA only if system-level testing confirms need for >400 W rating and board layout accommodates larger axial package. |
Compared with SMBJ24CA and 1.5KE24CA, BZW04-23HE3/54 offers optimal balance of AEC-Q101 qualification, ultra-low leakage, DO-41 compatibility with existing through-hole tooling, and precise 23.1 V standoff - making it the preferred choice for cost-sensitive, high-volume automotive and industrial control designs requiring proven reliability and drop-in manufacturability.

FAQ
What is the polarity configuration of BZW04-23HE3/54?
BZW04-23HE3/54 is a bidirectional TVS diode with symmetrical electrical characteristics in both directions. It has no cathode marking and is intended for use on AC-coupled or differential signal lines where polarity reversal may occur. This configuration ensures consistent clamping behavior regardless of transient polarity - a key requirement for protecting CAN, LIN, and RS-485 interfaces. The HE3 suffix confirms AEC-Q101 qualification and class 2 whisker resistance.
How does BZW04-23HE3/54 differ from unidirectional variants like BZW04-23E3/54?
BZW04-23HE3/54 differs from unidirectional versions by having identical VBR, VC, and IPPM ratings in both polarities and no cathode band marking. Unidirectional types include a color band denoting the cathode and support forward conduction only - making them unsuitable for AC or bidirectional data lines. BZW04-23HE3/54's symmetry allows direct replacement in circuits subject to voltage reversals, such as automotive sensor excitation lines or half-duplex communication buses.
What is the maximum clamping voltage of BZW04-23HE3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-23HE3/54 is 37.5 V at a peak pulse current (IPPM) of 10.7 A with a 10/1000 μs waveform. This value represents the upper limit of voltage seen by downstream circuitry during worst-case transient events and is measured after the device enters avalanche conduction. It ensures protected ICs - such as microcontrollers or transceivers - remain within absolute maximum ratings even during repetitive 400 W surges.
Is BZW04-23HE3/54 suitable for use in automotive under-hood applications?
Yes, BZW04-23HE3/54 is explicitly AEC-Q101 qualified and rated for junction temperatures up to +175 °C, making it suitable for under-hood automotive applications including engine control units, transmission control modules, and ADAS sensor nodes. Its glass-passivated junction, UL 94 V-0 molding, and class 2 whisker resistance further ensure long-term reliability in high-vibration, high-temperature, and high-humidity environments typical of powertrain systems.
What packaging format is used for BZW04-23HE3/54?
BZW04-23HE3/54 is supplied in 13-inch diameter paper tape and reel packaging with a base quantity of 550 units per reel (package code 54). The HE3 suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD201 class 2 whisker resistance. This packaging supports automated pick-and-place assembly and is compatible with standard axial-leaded component feeders used in high-volume automotive and industrial manufacturing lines.
