Product details
Overview
BZW04-102HE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 102 V standoff voltage (VWM), 114–126 V breakdown range (VBR at 1 mA), 165 V clamping voltage (VC) at 2.4 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor signal lines, industrial I/O ports, and telecom interface protection.
For engineers reviewing the BZW04-102HE3/54 datasheet, BZW04-102HE3/54 pinout, BZW04-102HE3/54 application, or BZW04-102HE3/54 equivalent, this AEC-Q101 qualified TVS offers verified bidirectional surge suppression, low leakage (<1 μA at VWM), and stable thermal performance up to +175 °C junction temperature - critical for high-reliability embedded power rail and data line hardening.
Technical Context
This device operates as a voltage-clamped shunt protector: under transient overvoltage exceeding VBR, it avalanches rapidly to clamp the line at ≤165 V while diverting up to 2.4 A (10/1000 μs). Its glass-passivated junction ensures consistent avalanche behavior and low incremental surge resistance.
Designed for bidirectional operation, BZW04-102HE3/54 has no polarity marking and symmetrical VBR/VC characteristics in both directions. It meets JESD22-B102 solderability standards and supports reflow and wave soldering with 275 °C/10 s max solder dip tolerance.
Key Specifications

Use Value: Symmetrical 102 V standoff allows direct integration into balanced lines without polarity concerns; 165 V clamping aligns with Ethernet PHY absolute max ratings. |
Use Scenario: Secondary-side overvoltage protection on 12 V/19 V DC outputs of wall adapters and USB-C PD chargers against output short-circuit recovery spikes. IC Role / Device Role / Timing Role: Fast-response shunt limiter that activates within nanoseconds to prevent output overvoltage from damaging connected devices. Use Value: Low 1 μA leakage avoids loading regulated outputs; DO-41 package enables cost-effective through-hole mounting in high-volume consumer power supplies. |
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; SMC package (surface-mount); 1000 W PPPM | Requires polarity-aware layout; better suited for PCB space-constrained designs needing higher surge rating. | Select SMBJ100A when board area is limited and unidirectional protection suffices; not drop-in due to package and polarity. |
| P6KE100A | Unidirectional; 100 V VWM; DO-15 package; 600 W PPPM; higher VC (165 V same, but higher IPPM = 3.6 A) | Larger DO-15 footprint; lower surge endurance per cycle than BZW04-102HE3/54's 400 W rating at rated IPPM. | Choose P6KE100A only if legacy DO-15 compatibility is required; verify thermal derating above 75 °C due to lower PD (5 W vs. 1.5 W). |
Compared with SMBJ100A and P6KE100A, BZW04-102HE3/54 provides AEC-Q101 qualification, bidirectional symmetry, and DO-41 through-hole robustness - making it optimal for automotive and industrial applications where reliability, polarity insensitivity, and mechanical stability are prioritized over raw surge wattage or miniaturization.
