Product details
Overview
BZW04-64BHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features 64.1 V stand-off voltage (VWM), 71.3–78.8 V breakdown voltage (VBR) at 1 mA, 103 V maximum clamping voltage (VC) at 3.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and industrial I/O circuits.
For engineers reviewing the BZW04-64BHE3/54 datasheet, BZW04-64BHE3/54 pinout, BZW04-64BHE3/54 application, or BZW04-64BHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical data, clamping performance under surge conditions, and direct alternatives for automotive-grade transient protection design.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with no polarity marking on the device body. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for suppressing ESD and inductive switching spikes before sensitive downstream components are damaged.
Rated for 175 °C maximum junction temperature and qualified to AEC-Q101, the BZW04-64BHE3/54 supports automotive and industrial environments where thermal stability and reliability under repetitive surge stress (0.01% duty cycle) are mandatory. It exhibits a +0.105 %/°C temperature coefficient of VBR, ensuring predictable voltage clamping across operating temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V - maximum continuous reverse working voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (min/max) | 71.3 V / 78.8 V at 1 mA - guaranteed breakdown range ensures consistent turn-on behavior across production lots. |
| VC @ IPPM | 103 V at 3.9 A - clamping voltage during 10/1000 μs surge; limits stress on protected ICs to safe levels. |
| PPPM | 400 W - peak pulse power handling capability; determines survivability against standardized lightning/surge waveforms. |
| IPPM | 3.9 A - peak pulse current corresponding to VC; used to size series impedance and verify system-level surge compliance. |

IC Role / Device Role / Timing Role: Mounted across motor terminals or H-bridge outputs to divert inductive energy away from MOSFETs and gate drivers. Use Value: 175 °C rated junction temperature allows placement near hot motor windings without derating - reduces board space vs. lower-TJ alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Same VWM (64 V), higher PPPM (600 W), SMA package (smaller footprint, lower thermal mass) | Preferred for space-constrained designs; requires PCB layout revision due to SMD mounting and different thermal dissipation profile | Select SMBJ64CA when board area is limited and surge duty cycle remains low; verify thermal relief pad design for 175 °C operation. |
| 1.5KE68CA | Higher VWM (68 V), same DO-41 package, 1500 W PPPM, but not AEC-Q101 qualified | Suitable for commercial/industrial use only; lacks automotive qualification and has looser VBR tolerance (±5% vs. ±5.5% for BZW04-64BHE3/54) | Choose 1.5KE68CA for cost-sensitive non-automotive systems where AEC-Q101 is not mandated and higher clamping voltage (115 V) is acceptable. |
Compared with SMBJ64CA and 1.5KE68CA, the BZW04-64BHE3/54 uniquely combines AEC-Q101 qualification, DO-41 through-hole robustness, and precise 64.1 V VWM - making it optimal for automotive and high-reliability industrial replacements where leaded mounting and automotive traceability are required.

FAQ
What is the clamping voltage of the BZW04-64BHE3/54 under a 10/1000 μs surge?
The BZW04-64BHE3/54 clamps to a maximum of 103 V at 3.9 A peak pulse current (IPPM) when subjected to a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C) and defines the upper voltage limit imposed on protected circuitry during transient events. The BZW04-64BHE3/54 maintains this clamping performance across its qualified operating temperature range.
Is the BZW04-64BHE3/54 suitable for automotive applications?
Yes, the BZW04-64BHE3/54 is AEC-Q101 qualified and manufactured with HE3 suffix indicating automotive-grade qualification, including stress testing for high-temperature operating life, temperature cycling, and humidity bias. Its 175 °C maximum junction temperature and DO-41 mechanical robustness make the BZW04-64BHE3/54 appropriate for engine control units, body electronics, and ADAS sensor interfaces.
Does the BZW04-64BHE3/54 have polarity markings?
No, the BZW04-64BHE3/54 is a bidirectional TVS diode and carries no polarity marking on the DO-41 package body. Its symmetrical construction means both terminals perform identically - it conducts during overvoltage events regardless of voltage polarity. This eliminates orientation concerns during PCB assembly and simplifies layout for differential or AC-coupled signal lines.
What is the standoff voltage (VWM) of the BZW04-64BHE3/54?
The standoff voltage (VWM) of the BZW04-64BHE3/54 is 64.1 V - the maximum DC or RMS voltage that can be continuously applied without triggering significant conduction. This parameter ensures reliable operation under normal conditions while maintaining sufficient margin below the 71.3 V minimum breakdown voltage. The BZW04-64BHE3/54 remains in high-impedance state until transients exceed VBR.
How does the BZW04-64BHE3/54 differ from unidirectional variants like BZW04-64HE3/54?
The BZW04-64BHE3/54 is bidirectional (denoted by "B" suffix), providing symmetrical clamping in both polarities with no cathode marking, whereas BZW04-64HE3/54 is unidirectional and features a band-marked cathode end. Their VWM, VBR, and VC values are identical, but the BZW04-64BHE3/54 is selected for AC signal lines, transformer-coupled interfaces, or any application requiring polarity-agnostic protection - unlike unidirectional types used on DC rails with defined ground reference.
