Product details
Overview
BZG04-100TR3 from Vishay Semiconductors is a glass-passivated, 100 V standoff Zener diode in DO-214AC (SMA) package, rated for 3 W steady-state power dissipation at 100 °C ambient, 300 W non-repetitive surge power (10/1000 µs), and 50 A peak forward surge current - used for transient voltage suppression in DC power rails and signal line protection.
For engineers reviewing the BZG04-100TR3 datasheet, BZG04-100TR3 pinout, BZG04-100TR3 application, or BZG04-100TR3 equivalent, key selection criteria include clamping voltage (167 V @ 1.8 A), junction capacitance (170 pF @ 0 V), thermal resistance (100 K/W on Al₂O₃ ceramic), and RoHS-compliant lead-free construction.
Technical Context
The BZG04-100TR3 operates as a unidirectional voltage-clamping device with a nominal breakdown voltage of 114 V @ 5 mA, ±10 % tolerance, and temperature coefficient of +0.09 %/K. Its fast response time (≤1 ps) enables effective suppression of ESD and lightning-induced transients.
Designed for surface-mount PCB assembly, it uses a glass-passivated junction to ensure stable Zener characteristics and high reliability under repeated surge stress. The DO-214AC case supports automated pick-and-place and provides mechanical robustness for industrial environments.
Key Specifications

| Clamping Voltage | 167 V @ 1.8 A - peak voltage seen during 10/1000 µs surge, critical for protected circuit margin |
| Junction Capacitance | 170 pF @ 0 V, 1 MHz - limits high-frequency noise coupling in signal-line applications |
| Surge Power Rating | 300 W (10/1000 µs) - defines single-event energy handling capability |
| Thermal Resistance | 100 K/W on Al₂O₃ ceramic - determines junction temperature rise under sustained power |

Applications
| Industrial Motor Drive DC Bus Protection | Telecom Line Card Surge Suppression |
|---|---|
Use Scenario: Protecting 100 V DC bus in variable-frequency drives from switching transients and regenerative energy spikes. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed across bus rails to clamp overvoltage events. Use Value: Limits bus voltage excursion to ≤167 V during 300 W surges, preventing IGBT gate driver damage and capacitor overvoltage failure. | Use Scenario: Safeguarding analog interface circuits on telecom line cards exposed to induced lightning surges on twisted-pair lines. IC Role / Device Role / Timing Role: Standoff-rated Zener clamp on low-bandwidth signal paths (e.g., supervisory or control lines). Use Value: 170 pF junction capacitance avoids signal integrity degradation while delivering 167 V clamping at 1.8 A peak current. |
| Renewable Energy Inverter DC Link | Test Equipment High-Voltage Input Protection |
Use Scenario: Clamping voltage overshoot on photovoltaic inverter DC link during rapid load disconnection or grid fault recovery. IC Role / Device Role / Timing Role: Primary overvoltage protection element mounted directly at DC link capacitor terminals. Use Value: 100 K/W thermal resistance on Al₂O₃ substrate enables reliable operation at 100 °C ambient without forced cooling. | Use Scenario: Protecting precision ADC front-end inputs in portable high-voltage test meters subjected to accidental 100 V misconnection. IC Role / Device Role / Timing Role: Fail-safe shunt limiter that conducts only during overvoltage, preserving measurement accuracy at normal operating voltage. Use Value: 114 V breakdown tolerance ensures no conduction below 100 V nominal input, eliminating offset error or loading effects. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Higher clamping voltage (165 V min), same DO-214AA package, 600 W surge rating | Optimized for higher-energy IEC 61000-4-5 tests; slightly larger footprint than DO-214AC | Select when surge energy exceeds 300 W or when SMB package mounting is preferred |
| P6SMB100A | Same 100 V standoff, 600 W surge rating, DO-214AA (SMB) package, 1000 pF capacitance | Higher junction capacitance reduces suitability for signal-line use but improves low-frequency surge absorption | Prefer for bulk DC rail protection where capacitance is not critical and higher surge margin is required |
Compared with SMBJ100A and P6SMB100A, the BZG04-100TR3 offers tighter clamping (167 V vs. ≥165 V), lower capacitance (170 pF vs. ≥1000 pF), and DO-214AC packaging - making it optimal for space-constrained, high-speed, or signal-integrity-sensitive 100 V protection tasks.

FAQ
What is the maximum clamping voltage of the BZG04-100TR3 under standard surge conditions?
The BZG04-100TR3 has a maximum clamping voltage of 167 V when subjected to a 10/1000 µs surge waveform at 1.8 A peak current. This value is measured per the Electrical Characteristics table in Vishay Document 85594 Rev. 2.2 and defines the upper voltage limit seen by protected circuitry during transient events. The BZG04-100TR3 maintains this clamping performance across its specified operating temperature range.
Is the BZG04-100TR3 suitable for bidirectional transient protection?
No - the BZG04-100TR3 is a unidirectional Zener diode designed for reverse-bias clamping only. It does not provide symmetrical protection like a TVS diode array or back-to-back Zener configuration. For bidirectional applications, two BZG04-100TR3 devices may be used in series opposition, but the BZG04-100TR3 itself functions strictly as a single-polarity clamp.
What is the thermal resistance of the BZG04-100TR3 when mounted on an aluminum oxide ceramic substrate?
When mounted on an Al₂O₃ ceramic substrate per Figure 1b in Vishay Document 85594, the BZG04-100TR3 exhibits a junction-to-ambient thermal resistance (RthJA) of 100 K/W. This value enables accurate junction temperature calculation under steady-state power dissipation and is critical for reliability validation in high-temperature environments where the BZG04-100TR3 operates.
Does the BZG04-100TR3 meet RoHS and lead-free requirements?
Yes - the BZG04-100TR3 is explicitly stated as lead (Pb)-free and compliant with RoHS Directive 2002/95/EC and WEEE Directive 2002/96/EC per Vishay Document 85594 Rev. 2.2. Its termination finish and internal construction are certified ozone-depleting-substance-free and conform to global environmental regulations applicable to commercial and industrial electronics.
How does the junction capacitance of the BZG04-100TR3 affect its use in signal-line protection?
With a typical junction capacitance of 170 pF at 0 V and 1 MHz, the BZG04-100TR3 introduces minimal loading on low-to-medium frequency signal paths (e.g., <1 MHz control lines), preserving signal integrity while providing effective clamping. This capacitance is significantly lower than alternatives like P6SMB100A (1000 pF), making the BZG04-100TR3 preferable for applications where bandwidth and rise-time preservation are critical alongside 100 V standoff protection.
