Product details
Overview
BZW04-23B-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal and power lines. It features a 23.1 V standoff voltage (VWM), 25.7–28.4 V breakdown voltage (VBR) at 1 mA, 37.5 V maximum clamping voltage (VC) at 10.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - suitable for protecting MOSFET gates, sensor interfaces, and industrial I/O lines against ESD and inductive switching surges.
For engineers reviewing the BZW04-23B-E3/54 datasheet, BZW04-23B-E3/54 pinout, BZW04-23B-E3/54 application, or BZW04-23B-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 through-hole compatibility, AEC-Q101 qualification status, low leakage (<1 μA at VWM), and thermal stability up to +175 °C junction temperature.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche behavior in both polarities, enabling robust surge suppression without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, critical for repeatable transient response under repetitive 0.01% duty cycle conditions.
The BZW04-23B-E3/54 delivers 400 W peak pulse power handling per 10/1000 μs waveform while maintaining tight VBR tolerance (±5% typical) and low temperature coefficient (0.096 %/°C), supporting reliable operation across automotive (-55 °C to +175 °C) and industrial ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 23.1 V - maximum continuous reverse working voltage before clamping initiates |
| VBR min/max | 25.7 V / 28.4 V at 1 mA - precise bidirectional avalanche threshold for predictable turn-on |
| VC @ IPPM | 37.5 V at 10.7 A - clamped voltage during 10/1000 μs surge, limiting downstream stress |
| PPPM | 400 W - peak transient energy absorption capacity under standard waveform |

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 | Surface-mount SMB package; 24 V VWM; same 400 W PPPM but lower VC (38.9 V); higher capacitance (~150 pF) | Better suited for high-density PCBs where space is constrained; less ideal for high-frequency signal lines due to higher junction capacitance | Select when automated SMT assembly is required and board real estate is limited; verify layout thermal relief for 1.5 W PD. |
| P6KE27CA | Higher VWM (27 V); larger DO-15 package; same 400 W rating but higher VC (45.7 V); non-AEC-Q101 rated | Acceptable for commercial/industrial use where automotive qualification is not mandated; less precise clamping margin for 24 V systems | Choose for cost-sensitive non-automotive designs needing broader VWM tolerance; avoid in AEC-Q101–mandated environments. |
Compared with SMBJ24CA and P6KE27CA, the BZW04-23B-E3/54 provides tighter VWM/VBR matching for 24 V nominal systems, AEC-Q101 compliance for automotive deployment, and lower junction capacitance - making it optimal for legacy through-hole designs requiring certified reliability and minimal signal distortion.

FAQ
What is the polarity configuration of BZW04-23B-E3/54?
The BZW04-23B-E3/54 is a bidirectional TVS diode with symmetrical avalanche characteristics in both directions. It has no cathode marking or polarity designation - either lead may be connected to the line or ground side of the protected circuit, simplifying layout and eliminating orientation errors during assembly.
Is BZW04-23B-E3/54 qualified for automotive applications?
Yes, BZW04-23B-E3/54 is AEC-Q101 qualified, having passed stress tests including temperature cycling, high-temperature reverse bias, and accelerated life testing. This certification confirms its suitability for automotive powertrain, body electronics, and ADAS subsystems where reliability under thermal and electrical stress is critical.
What is the maximum clamping voltage of BZW04-23B-E3/54 under surge conditions?
The BZW04-23B-E3/54 exhibits a maximum clamping voltage (VC) of 37.5 V at 10.7 A peak pulse current using the standard 10/1000 μs waveform. This value ensures protected downstream components experience minimal overvoltage stress during transient events such as ESD or inductive switching.
Can BZW04-23B-E3/54 replace unidirectional TVS diodes in existing designs?
No - BZW04-23B-E3/54 is strictly bidirectional and must not be substituted for unidirectional types like BZW04-23-E3/54 without circuit review. Unidirectional variants include a cathode band and conduct forward current; using the bidirectional version in forward-biased DC paths may cause unintended conduction or failure.
What packaging format is used for BZW04-23B-E3/54?
BZW04-23B-E3/54 is supplied in 13-inch paper tape and reel packaging (package code "54") with a base quantity of 550 units per reel. The E3 suffix indicates RoHS-compliant, commercial-grade construction with JESD201 Class 1A whisker resistance.
