Product details
Overview
BZG04-16TR3 from Vishay Semiconductors is a glass-passivated, lead-free Zener diode optimized for transient voltage suppression in high-energy surge environments. It features a nominal standoff voltage of 16 V, clamping voltage of 28.4 V at 10.6 A peak pulse current (10/1000 µs), and delivers 300 W non-repetitive peak surge power dissipation. Used in DC power rail protection for industrial control modules and automotive body electronics.
For engineers reviewing the BZG04-16TR3 datasheet, BZG04-16TR3 pinout, BZG04-16TR3 application, or BZG04-16TR3 equivalent, key selection criteria include its DO-214AC package thermal resistance (125 K/W on epoxy-glass hard tissue), 150 °C junction temperature rating, and verified clamping performance under standardized surge waveforms.
Technical Context
The BZG04-16TR3 operates as a unidirectional voltage-clamping device with a precisely defined Zener breakdown voltage (18.8 V min at 25 mA) and low dynamic impedance. Its fast response time (≤1 ps from 0 to VZmin) enables effective suppression of sub-nanosecond transients in sensitive analog and digital supply lines.
Designed for surface-mount mounting on PCBs with copper overlays, it relies on thermal conduction through leads (RthJL = 25 K/W) and exhibits graded thermal resistance to ambient depending on board layout-125 K/W on epoxy-glass hard tissue (Fig. 1b) and 100 K/W on Al2O3 ceramic substrates.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener-based transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Higher clamping voltage (26.0 V @ 12.9 A), same DO-214AA package, higher PPPM (600 W) | Optimized for higher-current, lower-voltage-clamp systems; less precise Zener regulation | Select when surge current exceeds 10.6 A but tighter voltage regulation is not required |
| P6SMB16A | Same clamping voltage (26.0 V @ 12.9 A), identical DO-214AA footprint, 600 W PPPM, higher IFSM (100 A) | Designed for broader industrial surge standards (IEC 61000-4-5); slightly higher leakage at VR | Prefer for designs requiring certified compliance with Level 4 surge immunity testing |
Compared with SMBJ16A and P6SMB16A, the BZG04-16TR3 offers tighter Zener voltage tolerance (18.8 V min vs. 16.0 V nominal), lower clamping voltage (28.4 V vs. 26.0 V), and superior thermal resistance control on standard FR4 layouts-making it optimal for precision-regulated 12–16 V systems where voltage margin is constrained.

FAQ
What is the Zener breakdown voltage specification for BZG04-16TR3?
The BZG04-16TR3 has a minimum Zener breakdown voltage of 18.8 V at 25 mA test current, with a typical value of 20.3 V and maximum of 22.9 V. This ensures reliable conduction onset above the 16 V standoff rating while maintaining sufficient margin against normal operating voltage fluctuations on 12 V systems. The BZG04-16TR3 datasheet specifies this parameter under Tamb = 25 °C with tight statistical control across production lots.
Is BZG04-16TR3 suitable for bidirectional transient protection?
No, the BZG04-16TR3 is a unidirectional Zener diode intended for DC rail clamping only. It conducts in reverse bias above its breakdown voltage and forward-biases like a standard diode below ~1.2 V. For bidirectional protection, a pair of BZG04-16TR3 devices in series opposition or a dedicated bidirectional TVS such as SMAJ16CA would be required. The BZG04-16TR3 design does not support symmetrical clamping.
What is the maximum allowable junction temperature for BZG04-16TR3?
The absolute maximum junction temperature for BZG04-16TR3 is 150 °C, as specified in Vishay Document Number 85594 Rev. 2.2. Operation beyond this limit risks irreversible degradation of the glass-passivated junction and accelerated parameter drift. Derating curves in the BZG04-16TR3 datasheet show power dissipation must be reduced linearly above 100 °C ambient when RthJA < 25 K/W, or above 50 °C when RthJA < 100 K/W.
How does the clamping voltage of BZG04-16TR3 compare to its standoff voltage?
The BZG04-16TR3 has a 16 V standoff voltage (VR) but clamps at 28.4 V under a 10/1000 µs surge at 10.6 A. This 12.4 V differential reflects the dynamic impedance rise during high-current avalanche conduction and defines the actual overvoltage stress imposed on downstream circuitry. Designers must ensure all protected components tolerate this clamped level, as the BZG04-16TR3 does not regulate at 16 V during surge events.
What packaging option does BZG04-16TR3 use, and how many units are in a reel?
The BZG04-16TR3 is supplied in TR3 packaging: 6,000 units per 13-inch reel, packed 6,000 per box. This format supports high-volume automated placement and is compatible with standard SMT feeders. The "TR3" suffix explicitly denotes this configuration in the BZG04-16TR3 part number, distinguishing it from the 1.5 k 7-inch reel (TR) variant. Traceability and moisture sensitivity level (MSL) information are provided per reel label per Vishay's quality documentation for BZG04-16TR3.
