Product details
Overview
BZG04-56TR3 from Vishay Semiconductors is a glass-passivated, surface-mount Zener diode designed for high-energy transient voltage suppression in power supply and interface protection circuits. It features a nominal Zener breakdown voltage of 64 V at 10 mA, clamping voltage of 94.4 V at 3.2 A (10/1000 µs pulse), 300 W non-repetitive peak surge power rating, and DO-214AC (SMC) package for robust thermal performance in industrial power converters.
For engineers reviewing the BZG04-56TR3 datasheet, BZG04-56TR3 pinout, BZG04-56TR3 application, or BZG04-56TR3 equivalent, key selection criteria include its 64 V breakdown tolerance, 94.4 V clamping level under 3.2 A surge, 300 W surge capability, DO-214AC thermal resistance (100 K/W on Al₂O₃), and RoHS-compliant lead-free construction.
Technical Context
The BZG04-56TR3 operates as a unidirectional voltage-clamping device with a precisely defined Zener breakdown threshold, optimized for fast transient response (≤1 ps rise time) and stable regulation under high-current surges. Its glass-passivated junction ensures long-term reliability in harsh environments, while its thermal design supports mounting on aluminum oxide ceramic substrates for enhanced power dissipation.
It delivers consistent clamping behavior across temperature due to a low voltage temperature coefficient (TKVZ = +0.08 %/K) and maintains low junction capacitance (291 pF at 0 V) to minimize signal distortion in DC-biased protection paths. The device is rated for 150 °C maximum junction temperature and 50 A peak forward surge current.

IC Role / Device Role / Timing Role: Standoff protector on 12 V supply rail, conducting only during >64 V excursions to shunt surge energy to ground. Use Value: Maintains 291 pF capacitance to avoid LIN signal edge degradation while clamping transients up to 300 W. |
| Telecom AC-DC Adapter Input Stage | Renewable Energy Inverter DC Link |
Use Scenario: Safeguarding bridge rectifier outputs and bulk capacitor charging circuits against AC line surges (IEC 61000-4-5). IC Role / Device Role / Timing Role: Secondary overvoltage clamp parallel to bulk capacitor, triggered when rectified voltage exceeds 64 V. Use Value: Absorbs 300 W surge energy without thermal runaway, enabling compact adapter designs with no external heatsink required. | Use Scenario: Mitigating switching transients on 600 V DC link capacitors in solar string inverters during IGBT turn-off. IC Role / Device Role / Timing Role: Snubber-assisted voltage clamp on intermediate DC bus, operating in conjunction with RC snubbers to reduce dV/dt stress.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A | Higher clamping voltage (93.6 V at 3.3 A), same DO-214AA package, lower surge rating (600 W vs. 300 W) | Designed for bidirectional surge suppression; lacks precise Zener regulation in forward bias | Select for higher-energy unidirectional surges where tighter voltage tolerance is secondary to peak power handling |
| P6SMB56A | Same 56 V standoff, but 600 W surge rating, DO-214AA package, 1000 W peak pulse rating | Higher leakage (5 µA vs. 5 µA), identical clamping (93.6 V), larger thermal resistance (150 K/W) | Prefer when board layout allows larger footprint and system requires higher single-pulse margin at cost of thermal efficiency |
Compared with SMBJ58A and P6SMB56A, the BZG04-56TR3 offers superior thermal resistance (100 K/W on Al₂O₃), tighter Zener voltage tolerance (±5 %), and lower junction capacitance (291 pF), making it optimal for space-constrained, thermally demanding 48–60 V DC systems requiring precise clamping and long-term stability.

FAQ
What is the Zener breakdown voltage specification for BZG04-56TR3?
The BZG04-56TR3 has a nominal Zener breakdown voltage of 64 V at test current IZT = 10 mA, with a minimum of 60 V and maximum of 68 V per the Vishay BZG04-Series datasheet (Doc. 85594 Rev. 2.2). This value is measured under controlled 25 °C ambient conditions and defines the primary voltage regulation threshold for the BZG04-56TR3 in reverse-bias operation.
Does BZG04-56TR3 meet RoHS requirements?
Yes, the BZG04-56TR3 is certified lead (Pb)-free and fully compliant with EU RoHS Directive 2002/95/EC and WEEE Directive 2002/96/EC, as explicitly stated in the Vishay BZG04-Series datasheet. Vishay confirms that no ozone-depleting substances are used in the manufacturing or composition of the BZG04-56TR3.
What is the maximum clamping voltage of BZG04-56TR3 under surge conditions?
The BZG04-56TR3 exhibits a maximum clamping voltage of 94.4 V when subjected to a 10/1000 µs surge current pulse of 3.2 A, as specified in the Electrical Characteristics table of the official Vishay datasheet. This clamping voltage represents the upper bound of voltage seen by protected circuitry during transient events and is a critical parameter for BZG04-56TR3 system-level surge design.
Which package type does BZG04-56TR3 use, and what are its mechanical dimensions?
The BZG04-56TR3 uses the DO-214AC (also known as SMC) surface-mount package, with mechanical dimensions of 7.11 mm × 6.22 mm × 2.39 mm and approximate weight of 77 mg. This package is standardized per JEDEC and provides a robust thermal path for the BZG04-56TR3 in high-power dissipation applications.
Can BZG04-56TR3 be used in automotive applications such as load-dump protection?
Yes, the BZG04-56TR3 is suitable for automotive load-dump protection (ISO 7637-2 Pulse 5a) due to its 300 W non-repetitive surge power rating, 50 A peak forward surge current capability, and 150 °C maximum junction temperature rating. Its 94.4 V clamping voltage at 3.2 A aligns with typical 24 V system protection requirements, making the BZG04-56TR3 a validated choice for BCM and power module designs.
