Product details
Overview
BZG04-13TR3 from Vishay Semiconductors is a glass-passivated, surface-mount Zener diode rated for 13 V standoff voltage, 3 W steady-state power dissipation at 100 °C ambient (with RthJA < 25 K/W), and 300 W non-repetitive peak surge power (10/1000 µs pulse). It delivers clamping voltage of 22.9 V at 13.1 A surge current and exhibits fast response time ≤ 1 ps, making it suitable for transient overvoltage protection in DC power rails and I/O interfaces.
For engineers reviewing the BZG04-13TR3 datasheet, BZG04-13TR3 pinout, BZG04-13TR3 application, or BZG04-13TR3 equivalent, key selection criteria include its DO-214AC package, 13 V nominal Zener voltage with ±5 % tolerance, 25 mA test current, 0.06 %/K temperature coefficient, and verified 785 pF junction capacitance at 0 V - all critical for ESD/surge co-design in automotive body electronics and industrial PLC inputs.
Technical Context
The BZG04-13TR3 operates as a unidirectional voltage-clamping device in reverse-biased configuration, leveraging a glass-passivated PN junction to sustain high-energy transients without thermal runaway. Its thermal resistance from junction-to-lead is 25 K/W, enabling effective heat transfer to PCB copper when mounted per Fig. 1b on Al₂O₃ ceramic substrate (RthJA = 100 K/W).
Designed for single-pulse suppression, it supports 50 A peak forward surge current (10 ms half-sine) and maintains stable breakdown behavior across -65 °C to +150 °C storage and operating ranges. The 13 V Zener voltage is specified at 25 mA test current (IZT), with clamping performance validated under standardized 10/1000 µs surge waveforms.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Higher clamping voltage (21.5 V @ 22.5 A), larger DO-214AA package, 600 W surge rating | Used where higher surge margin is required but tighter voltage tolerance is less critical | Select SMBJ13A when system-level surge testing exceeds IEC 61000-4-5 Level 4 or when board space allows larger footprint |
| BZX84-C13 | Smaller SOT-23 package, lower 500 mW power rating, 25 V clamping at 1 A, ±5 % VZ tolerance | Targeted at low-energy signal-line protection rather than power-rail clamping | Choose BZX84-C13 only for low-current logic-level interfaces where 3 W dissipation is unnecessary |
Compared with SMBJ13A and BZX84-C13, the BZG04-13TR3 uniquely balances 3 W steady-state capability, 300 W surge rating, and DO-214AC manufacturability - making it optimal for mid-power industrial and automotive clamping where thermal management and surge fidelity are jointly constrained.

FAQ
What is the Zener voltage tolerance for BZG04-13TR3?
The BZG04-13TR3 has a nominal Zener voltage of 13 V with a tolerance of ±5 %, measured at 25 mA test current (IZT) and 25 °C ambient. This tolerance is confirmed in the Electrical Characteristics table of Vishay Document Number 85594 Rev. 2.2, where the breakdown voltage range is specified as 15.3 V min to 15.3 V typ at IR = 5 µA - corresponding to the 13 V standoff rating. The BZG04-13TR3 maintains this specification across its qualified operating temperature range.
Does BZG04-13TR3 support bidirectional transient suppression?
No, the BZG04-13TR3 is a unidirectional Zener diode intended for reverse-bias clamping only. It does not provide symmetrical clamping for AC or bipolar transients. For bidirectional protection, a pair of BZG04-13TR3 devices in series opposition or a dedicated bidirectional TVS like SMAJ13CA would be required. The device's electrical characteristics, including forward voltage (VF = 1.2 V at IF = 0.5 A) and reverse breakdown behavior, are defined exclusively for unidirectional operation.
What is the maximum junction temperature rating for BZG04-13TR3?
The BZG04-13TR3 has a maximum junction temperature (Tj) rating of 150 °C, as specified in the Absolute Maximum Ratings section of Vishay Document Number 85594. This limit applies under all operating conditions, including surge events. Derating is required above 100 °C ambient - for example, power dissipation drops from 3 W at Tamb = 100 °C (with RthJA < 25 K/W) to 1.25 W at Tamb = 50 °C (with RthJA < 100 K/W). Thermal design must ensure Tj does not exceed 150 °C during worst-case surge or steady-state operation.
Is BZG04-13TR3 compatible with lead-free reflow soldering processes?
Yes, the BZG04-13TR3 is fully compatible with standard lead-free reflow profiles, including JEDEC J-STD-020D-compliant peak temperatures up to 260 °C. Its glass-passivated junction and DO-214AC package are qualified for multiple reflow cycles without degradation in Zener voltage stability or surge performance. Vishay explicitly states compliance with RoHS 2002/95/EC and confirms the part is lead (Pb)-free, verifying suitability for Pb-free assembly in high-reliability industrial and automotive production lines.
How does the junction capacitance of BZG04-13TR3 affect high-speed signal lines?
The BZG04-13TR3 exhibits 785 pF junction capacitance at VR = 0 V and f = 1 MHz, which may load high-speed signal paths if placed directly across data lines. In practice, it is recommended for power-rail or low-bandwidth I/O protection (e.g., digital inputs ≤1 MHz), not USB, CAN, or Ethernet interfaces. For such applications, the capacitance could attenuate edge rates or cause reflections; designers should verify signal integrity via SPICE simulation using the device's published Cj vs. VR curve before deployment. The BZG04-13TR3 remains optimal where clamping fidelity outweighs capacitive loading concerns.
