Product details
Overview
BZG04-62TR from Vishay Semiconductors is a glass-passivated Zener diode designed for transient voltage suppression in power rails and signal lines. It features a nominal Zener voltage of 62 V, 300 W non-repetitive peak surge power (10/1000 µs), 50 A peak forward surge current, and DO-214AC package. It is used in industrial power supply overvoltage clamping circuits where fast response (<1 ps) and high reliability are required.
For engineers reviewing the BZG04-62TR datasheet, BZG04-62TR pinout, BZG04-62TR application, or BZG04-62TR equivalent, key selection criteria include clamping voltage (103.5 V @ 2.9 A), thermal resistance (100 K/W on Al₂O₃ substrate), standoff voltage (62 V), surge robustness (300 W), and RoHS-compliant lead-free construction.
Technical Context
The BZG04-62TR operates as a unidirectional voltage clamp with precise breakdown at 62 V (min 70 V @ 10 mA). Its glass-passivated junction ensures stable Zener characteristics under thermal cycling and humidity stress. The device exhibits low junction capacitance (280 pF @ 0 V) and fast transient response due to minimal parasitic inductance inherent to the DO-214AC package.
Thermal performance is defined by three mounting configurations: RthJA = 150 K/W (epoxy-glass, Fig. 1a), 125 K/W (epoxy-glass, Fig. 1b), and 100 K/W (Al₂O₃ ceramic, Fig. 1b). Junction temperature is rated to 150 °C, enabling operation in harsh ambient environments up to +100 °C with derated power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 62 V nominal standoff; min 70 V @ 10 mA - defines precise clamping threshold for overvoltage events |
| Clamping Voltage (VCL) | 103.5 V @ 2.9 A (10/1000 µs) - maximum voltage seen by protected circuit during surge |
| Peak Surge Power | 300 W (10/1000 µs pulse) - enables handling of high-energy transients without failure |
| Junction Capacitance | 280 pF @ 0 V, 1 MHz - low enough for signal-line protection without bandwidth degradation |
| Thermal Resistance (RthJA) | 100 K/W on Al₂O₃ ceramic - supports sustained power dissipation in thermally demanding PCB layouts |
| Surge Current (IFSM) | 50 A (10 ms half-sine) - withstands repetitive inrush or fault currents in AC/DC front-ends |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | 64 V standoff, 600 W peak power, DO-214AA package, bidirectional | Higher surge rating but larger package footprint; requires polarity-aware layout | Select when higher surge margin is needed and board space allows DO-214AA |
| P6KE62A | 62 V standoff, 600 W peak power, DO-15 axial package, slower response (~1 ns) | Through-hole mounting only; unsuitable for high-density SMT designs | Choose for legacy through-hole systems where rework tolerance and cost outweigh SMT density needs |
Compared with SMBJ64A and P6KE62A, the BZG04-62TR offers optimal balance of precision 62 V clamping, compact DO-214AC footprint, sub-nanosecond response, and industrial thermal performance on ceramic substrates - making it preferred for space-constrained, high-reliability SMT power rail protection.

FAQ
What is the exact Zener breakdown voltage specification for BZG04-62TR?
The BZG04-62TR has a minimum Zener breakdown voltage of 70 V at test current IZT = 10 mA, with a typical value of 70 V and no maximum specified. This defines its precise clamping behavior under surge conditions and distinguishes it from generic 62 V-rated devices with wider tolerances.
Does BZG04-62TR support bidirectional transient suppression?
No, the BZG04-62TR is a unidirectional Zener diode. It clamps only in reverse bias above 70 V and conducts forward current up to 1.2 V at 0.5 A. For bidirectional protection, a paired configuration or dedicated TVS like SMBJ64CA is required.
What is the maximum allowable junction temperature for BZG04-62TR?
The absolute maximum junction temperature for BZG04-62TR is 150 °C. Operation beyond this limit risks irreversible degradation of the glass-passivated junction and permanent shift in Zener voltage characteristics.
How does the DO-214AC package affect thermal performance of BZG04-62TR?
The DO-214AC package enables RthJA = 100 K/W when mounted on Al₂O₃ ceramic substrate, allowing 1.25 W continuous power dissipation at Tamb = 50 °C. This outperforms epoxy-glass mounting (RthJA = 125–150 K/W) and supports higher sustained surge duty cycles.
Is BZG04-62TR compatible with lead-free reflow soldering processes?
Yes, BZG04-62TR is lead (Pb)-free and qualified for standard Pb-free reflow profiles (JEDEC J-STD-020), including peak temperatures up to 260 °C. Its glass passivation ensures intermetallic stability and prevents solder joint corrosion during thermal cycling.
