Product details
Overview
BZW04-10-E3/54 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 10.2 V stand-off voltage (VWM), 11.4–12.6 V breakdown voltage (VBR) at 1 mA, 16.7 V clamping voltage (VC) at 24 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - suitable for protecting automotive sensor interfaces and industrial I/O circuits against ESD and inductive switching transients.
For engineers reviewing the BZW04-10-E3/54 datasheet, BZW04-10-E3/54 pinout, BZW04-10-E3/54 application, or BZW04-10-E3/54 equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified bidirectional TVS for board-level surge immunity in DC power rails, analog sensor inputs, and low-speed communication lines where fast response (<1 ns), low leakage (<1 μA at VWM), and stable temperature coefficient (0.078 %/°C) are critical.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical breakdown and clamping characteristics in forward and reverse directions. Its glass-passivated junction ensures stable VBR tolerance (±5 % typical) and low incremental surge resistance, enabling consistent clamping performance under repetitive 400 W transient events at 0.01 % duty cycle.
The device complies with ANSI/IEEE C62.35 surge standards and supports operation across –55 °C to +175 °C junction temperature range. Its DO-41 package provides mechanical robustness and solderability per J-STD-002/JESD22-B102, with matte tin-plated leads and UL 94 V-0 molded epoxy encapsulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.2 V - Maximum continuous DC or RMS voltage the device blocks without significant leakage |
| VBR (min/max) | 11.4 V / 12.6 V at 1 mA - Ensures reliable triggering above normal operating voltage while accommodating process variation |
| VC @ IPPM | 16.7 V at 24 A - Limits transient voltage to safe levels for downstream 12 V logic or analog circuitry |
| IPPM | 24 A (10/1000 μs) - Withstands high-energy surges common in automotive load-dump or relay-coil flyback events |
| PPPM | 400 W - Delivers industry-standard surge immunity level for Class III/IV IEC 61000-4-5 applications |
| TJ max | +175 °C - Enables use in under-hood automotive environments and high-temperature industrial enclosures |
| Leakage @ VWM | <1 μA - Minimizes standby power loss and avoids false triggering in high-impedance sensor bias networks |
| Temp. coeff. of VBR | 0.078 %/°C - Predictable VBR drift over temperature supports stable protection threshold design |
Pinout & Package
DO-41 (DO-204AL) axial-leaded package with no polarity marking - symmetrical bidirectional construction means both leads serve as interchangeable terminals for transient suppression across AC or floating DC lines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

FAQ
What is the polarity configuration of BZW04-10-E3/54?
BZW04-10-E3/54 is a bidirectional TVS diode with symmetrical electrical characteristics in both directions. It has no cathode marking and functions identically regardless of terminal orientation - ideal for AC-coupled or floating DC protection applications where polarity cannot be guaranteed.
Does BZW04-10-E3/54 meet automotive qualification standards?
BZW04-10-E3/54 carries the E3 suffix, indicating RoHS-compliant commercial-grade construction. For automotive use, the HE3-suffixed variant (BZW04-10HE3/54) is AEC-Q101 qualified. The BZW04-10-E3/54 itself is not AEC-Q101 certified but shares identical electrical and thermal specs with the qualified version.
What is the maximum clamping voltage of BZW04-10-E3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-10-E3/54 is 16.7 V at 24 A peak pulse current with a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during standardized surge events and is measured per ANSI/IEEE C62.35.
Can BZW04-10-E3/54 be used in place of unidirectional TVS diodes?
No - BZW04-10-E3/54 is strictly bidirectional and must not replace unidirectional TVS diodes in DC-biased circuits requiring forward conduction blocking. Its symmetrical behavior makes it unsuitable for applications where reverse leakage during normal operation must be minimized beyond ±1 μA.
What packaging format is supplied for BZW04-10-E3/54?
BZW04-10-E3/54 is supplied in 13-inch diameter paper tape and reel packaging (package code "54"), with 550 units per reel. This format supports automated pick-and-place assembly and complies with EIA-481-D standards for surface-mount compatible handling.
