Product details
Overview
BZG04-30TR3 from Vishay Semiconductors is a glass-passivated Zener diode designed for transient voltage suppression in power rails and signal lines, with a nominal Zener breakdown voltage of 34 V at 10 mA, clamping voltage of 50.1 V at 6.0 A surge current, and peak surge power dissipation of 300 W (10/1000 µs pulse). It operates within -65 °C to +150 °C and is used in industrial power supply overvoltage protection circuits.
For engineers reviewing the BZG04-30TR3 datasheet, BZG04-30TR3 pinout, BZG04-30TR3 application, or BZG04-30TR3 equivalent, key selection criteria include its DO-214AC package, 30 V standoff rating, 3 W steady-state power dissipation at 100 °C ambient, fast ≤1 ps response time, and RoHS-compliant lead-free construction.
Technical Context
The BZG04-30TR3 functions as a unidirectional voltage-clamping device, leveraging a glass-passivated PN junction to maintain stable reverse breakdown behavior under transient stress. Its thermal resistance from junction-to-lead is 25 K/W, enabling efficient heat transfer to PCB copper when mounted per Figure 1b on Al₂O₃ ceramic substrate (RthJA = 100 K/W).
It delivers precise clamping performance with a typical junction capacitance of 450 pF at 0 V and exhibits low temperature coefficient of ±0.06 %/K, ensuring predictable voltage regulation across operating temperatures. The device sustains non-repetitive 50 A forward surge current for 10 ms half-sine wave events without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 34 V min / 34 V typ @ IZT = 10 mA - defines precise clamping threshold for 30 V nominal rail protection |
| Clamping Voltage (VCL) | 50.1 V max @ IPP = 6.0 A - limits transient overshoot during 10/1000 µs surge events |
| Peak Surge Power | 300 W @ tp = 10/1000 µs - supports high-energy transient absorption without failure |
| Junction-to-Lead Rth | 25 K/W - enables direct thermal path to PCB copper pour for sustained power handling |
| Standoff Voltage (VR) | 30 V max @ IR = 5 µA - ensures minimal leakage below rated system voltage |
| Junction Capacitance | 450 pF @ VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering capability in signal-line protection |
| Forward Voltage | 1.2 V max @ IF = 0.5 A - defines conduction loss during forward-biased fault conditions |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, epoxy-molded case with cathode band marking; weight ≈ 77 mg; compatible with standard reflow profiles per J-STD-020.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | Higher clamping voltage (53.3 V), larger DO-214AA package, bidirectional variant available | Designed for higher-energy IEC 61000-4-5 testing; less precise 30 V standoff tolerance | Select SMBJ30A when surge energy exceeds 300 W or bidirectional protection is required |
| P6SMB30A | Same DO-214AA package, 300 W rating, but 53.3 V clamping and 1000 W peak surge capability | Optimized for telecom-grade surge standards; higher leakage (10 µA vs. 5 µA) | Choose P6SMB30A for legacy designs requiring MIL-STD-1275E compliance or higher surge margin |
Compared with SMBJ30A and P6SMB30A, the BZG04-30TR3 offers tighter 34 V Zener tolerance, lower 50.1 V clamping, and DO-214AC's smaller footprint-making it optimal for space-constrained 30 V rail protection where precision clamping and thermal efficiency are critical.
