Product details
Overview
BZW04-102B-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 102 V standoff voltage (VWM), 114–126 V breakdown range (VBR), 165 V clamping voltage (VC) at 2.4 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 from ESD and inductive switching surges.
For engineers reviewing the BZW04-102B-E3/54 datasheet, BZW04-102B-E3/54 pinout, BZW04-102B-E3/54 application, or BZW04-102B-E3/54 equivalent, this page delivers verified electrical parameters, DO-41 terminal mapping, real-world protection use cases, and qualified AEC-Q101 alternatives for automotive and industrial designs requiring robust overvoltage immunity.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with no polarity marking on the DO-41 package. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing sub-microsecond transients induced by relay switching or lightning-induced surges.
Rated for 175 °C maximum junction temperature and compliant with AEC-Q101 (HE3 variant), the BZW04-102B-E3/54 sustains 1.5 W steady-state power dissipation at TL = 75 °C and exhibits a +0.107 %/°C temperature coefficient of VBR - enabling stable clamping performance across extended thermal ranges in motor control and power supply front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 102 V - maximum continuous reverse working voltage before conduction begins; defines safe operating margin for 100 V nominal bus lines. |
| VBR min/max | 114 V / 126 V at 1 mA test current - guaranteed breakdown onset window ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 165 V at 2.4 A - clamping voltage under 10/1000 μs surge; limits downstream device stress to ≤165 V during 400 W transient absorption. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Unidirectional; 100 V VWM; SMA package (surface-mount); 600 W PPPM; 170 V VC @ 3.5 A. | Requires polarity-aware PCB layout; better suited for space-constrained DC power rail protection where unidirectional operation is acceptable. | Select SMBJ100A when board area is limited and circuit topology permits cathode/anode orientation; not drop-in for bidirectional signal line use. |
| P6KE110CA | Same DO-41 package; bidirectional; 110 V VWM; 600 W PPPM; 177 V VC @ 3.4 A; higher leakage (5.0 μA). | Higher clamping voltage reduces protection margin for 100 V systems; suitable for less sensitive loads like relays or indicator LEDs. | Choose P6KE110CA only if 177 V clamping is acceptable and higher leakage does not impact sensor accuracy; verify thermal derating for sustained surge duty. |
Compared with BZW04-102B-E3/54, SMBJ100A offers higher surge power but requires polarity-aware placement and lacks AEC-Q101 qualification, while P6KE110CA matches the DO-41 form factor and bidirectionality but trades lower clamping performance and higher leakage - making BZW04-102B-E3/54 optimal for precision-sensitive, automotive-qualified signal-line protection.

FAQ
What is the clamping voltage of BZW04-102B-E3/54 under standard surge conditions?
The BZW04-102B-E3/54 has a maximum clamping voltage (VC) of 165 V when subjected to its rated peak pulse current of 2.4 A using the 10/1000 μs waveform. This value is measured per IEC 61000-4-5 and ensures downstream components see no more than 165 V during transient events - a critical parameter for protecting 200 V-rated MOSFETs or 170 V-tolerant interface ICs. The BZW04-102B-E3/54 maintains this clamping performance across its full operating temperature range.
Is BZW04-102B-E3/54 suitable for automotive applications?
Yes - the BZW04-102B-E3/54 is RoHS-compliant and manufactured to commercial-grade specifications; however, its HE3-suffix variant (BZW04-102B-HE3/54) is explicitly AEC-Q101 qualified for automotive use. The BZW04-102B-E3/54 shares identical electrical characteristics and DO-41 packaging but lacks the extended reliability validation required for under-hood or safety-critical modules. For non-safety automotive subsystems with less stringent qualification needs, the BZW04-102B-E3/54 remains viable.
How does the bidirectional nature of BZW04-102B-E3/54 affect PCB layout?
The BZW04-102B-E3/54 has no polarity marking and functions identically in either direction, eliminating orientation constraints during placement. Unlike unidirectional TVS diodes that require correct anode/cathode alignment relative to ground or supply rails, the BZW04-102B-E3/54 can be installed in any axial orientation - simplifying assembly, reducing misplacement risk, and enabling symmetric protection on differential or AC-coupled signal lines. This also avoids design errors in legacy schematics reused across bidirectional interfaces.
What is the maximum junction temperature rating for BZW04-102B-E3/54?
The BZW04-102B-E3/54 is rated for a maximum junction temperature (TJ max) of +175 °C, allowing reliable operation in high-ambient environments such as engine compartments, industrial inverters, or enclosed power supplies. This rating is supported by its glass-passivated chip construction and UL 94 V-0 epoxy package, which provide thermal stability and flame resistance. Derating curves in the datasheet confirm usable power dissipation down to 0 W at 175 °C ambient when mounted on standard FR-4 with 0.5-inch lead lengths.
Does BZW04-102B-E3/54 meet international surge immunity standards?
The BZW04-102B-E3/54 is designed to support compliance with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge) when properly integrated into a system-level protection scheme. Its 400 W peak pulse power rating and 165 V clamping voltage align with Level 4 EFT (2 kV) and 1 kV/2 Ω surge test requirements for industrial equipment. While the BZW04-102B-E3/54 itself is not certified to these standards, its validated electrical behavior enables designers to achieve pass-rates in end-equipment testing - confirmed by Vishay's application notes AN8001 and AN8005.
