Product details
Overview
BZW04-6V4B-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 or power lines. It features 6.40 V standoff voltage (VWM), 7.13–7.88 V breakdown voltage (VBR) at 10 mA test current, 11.3 V clamping voltage (VC) at 35.4 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used in automotive sensor interface protection and industrial I/O line surge suppression.
For engineers reviewing the BZW04-6V4B-E3/54 datasheet, BZW04-6V4B-E3/54 pinout, BZW04-6V4B-E3/54 application, or BZW04-6V4B-E3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-41 mechanical compatibility, low leakage (<500 μA at VWM), and thermal stability up to +175 °C junction temperature.
Technical Context
This device operates as a voltage-clamping protector with symmetrical bidirectional avalanche behavior, enabling transient suppression on AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance under repetitive 10/1000 μs pulses at 0.01% duty cycle.
The BZW04-6V4B-E3/54 exhibits a temperature coefficient of VBR of +0.061 %/°C and maintains clamping performance across -55 °C to +175 °C operating junction range. It is rated for 1.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C and supports soldering per JESD 22-B106 (275 °C max, 10 s).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.40 V - maximum continuous reverse working voltage before clamping initiates; defines safe operating margin for protected circuit. |
| VBR min/max | 7.13 V / 7.88 V at IT = 10 mA - verified avalanche onset range ensuring consistent turn-on during transients. |
| VC @ IPPM | 11.3 V at 35.4 A - clamped voltage during 400 W 10/1000 μs surge; limits downstream stress on ICs or MOSFETs. |
| PPPM | 400 W - peak pulse power handling capacity; enables robust protection against IEC 61000-4-5 Level 3 surges. |
| ID @ VWM | ≤500 μA - reverse leakage at standoff voltage; minimizes quiescent power loss in battery-powered systems. |

FAQ
What is the standoff voltage (VWM) specification for BZW04-6V4B-E3/54?
The BZW04-6V4B-E3/54 has a standoff voltage (VWM) of 6.40 V, meaning it remains non-conductive under continuous reverse bias up to this level. This value ensures compatibility with 5 V logic interfaces and low-voltage sensor signals while providing sufficient margin before avalanche conduction begins at its 7.13–7.88 V breakdown range.
Is BZW04-6V4B-E3/54 suitable for automotive applications?
Yes, BZW04-6V4B-E3/54 is AEC-Q101 qualified and specifically designed for automotive use cases such as sensor interface protection and infotainment system I/O line safeguarding. Its DO-41 package, -55 °C to +175 °C operating range, and validated surge performance meet stringent automotive reliability requirements.
Does BZW04-6V4B-E3/54 have polarity markings on the package?
No, BZW04-6V4B-E3/54 is a bidirectional TVS diode and carries no polarity marking - the device functions identically regardless of lead orientation. Unlike unidirectional types that feature a cathode band, this part uses symmetrical terminals optimized for AC or floating signal path protection.
What is the clamping voltage (VC) of BZW04-6V4B-E3/54 under surge conditions?
The BZW04-6V4B-E3/54 clamps to a maximum of 11.3 V when subjected to its rated 35.4 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This VC value directly determines the maximum voltage stress imposed on downstream components during transient events.
Can BZW04-6V4B-E3/54 be used in place of unidirectional TVS diodes?
No - BZW04-6V4B-E3/54 is strictly bidirectional and must not replace unidirectional TVS diodes in DC-biased circuits requiring cathode-anode polarity alignment. Its symmetrical structure makes it ideal for AC lines, differential pairs, or floating grounds, but unsuitable where forward conduction directionality is required.
