Product details
Overview
BZG04-36TR3 from Vishay Semiconductors is a glass-passivated, surface-mount Zener diode optimized for transient voltage suppression in high-energy surge environments. It features a nominal standoff voltage of 36 V, 300 W non-repetitive peak surge power (10/1000 µs), clamping voltage of 60.7 V at 4.9 A IPP, and DO-214AC (SMC) package. It is used in DC power rail protection for industrial motor drives.
For engineers reviewing the BZG04-36TR3 datasheet, BZG04-36TR3 pinout, BZG04-36TR3 application, or BZG04-36TR3 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, surge current handling at 10 ms half-sine, thermal resistance to PCB copper area, junction temperature limit of 150 °C, and RoHS-compliant lead-free construction.
Technical Context
The BZG04-36TR3 operates as a unidirectional voltage clamp with sharp Zener breakdown at 40 V (min) under 10 mA test current. Its fast response time (≤1 ps) enables effective suppression of ESD and lightning-induced transients before downstream components experience overvoltage stress.
Thermal performance depends on PCB mounting: RthJA is 150 K/W on epoxy-glass hard tissue (Fig. 1a), 125 K/W on same substrate with improved layout (Fig. 1b), and 100 K/W on Al₂O₃ ceramic - directly impacting sustained power dissipation capability in repetitive surge scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage | 36 V - maximum continuous reverse voltage before conduction begins; sets minimum operating margin above system nominal rail. |
| Zener Breakdown Voltage | 40 V min @ 10 mA - precise clamping threshold under standard test condition; ensures predictable turn-on during overvoltage events. |
| Clamping Voltage | 60.7 V @ 4.9 A IPP - peak voltage seen by protected circuit during 10/1000 µs surge; defines worst-case stress level. |
| Peak Surge Power | 300 W (10/1000 µs) - energy-handling capacity for single transient events; determines survivability against IEC 61000-4-5 Level 4 surges. |
| Junction Temperature Limit | 150 °C - maximum allowable die temperature; constrains thermal design and derating in high-ambient applications. |
| Package | DO-214AC (SMC) - standardized surface-mount outline with 77 mg mass and defined thermal pad footprint per Fig. 1. |
Pinout & Package
DO-214AC (SMC) package: molded plastic body with coplanar cathode and anode terminals; designed for reflow soldering on 2-layer or multilayer PCBs with thermal copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Current entry point during forward bias or surge conduction | Connected to ground or low-impedance return path; must handle 50 A peak forward surge current without bond wire failure. |
| Cathode (K) | Current exit point during reverse-bias clamping | Connected to protected line (e.g., 36 V rail); carries full surge current during transient; polarity marking visible on package body. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable Zener voltage over lifetime and humidity exposure; eliminates need for hermetic sealing in industrial environments. |
| Fast response time ≤1 ps | Ensures clamping activation before nanosecond-scale ESD pulses propagate into sensitive logic or analog circuits. |
| Lead (Pb)-free & RoHS-compliant | Meets EU Directive 2002/95/EC and WEEE 2002/96/EC; supports global manufacturing and end-of-life compliance requirements. |
| High reliability construction | Validated for >1000 surge cycles at rated PZSM; suitable for mission-critical protection in automotive body control modules. |
Applications
| Industrial Motor Drives | Programmable Logic Controllers |
|---|---|
Use Scenario: Protection of 36 V DC control bus against switching transients from contactor coil de-energization and regenerative braking feedback. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed between rail and ground, activated only during overvoltage events. Use Value: Limits rail excursion to ≤60.7 V, preventing latch-up or permanent damage to 40 V-rated microcontrollers and gate drivers. | Use Scenario: Input/output module protection against induced surges from adjacent 24–48 V field wiring in factory automation cabinets. IC Role / Device Role / Timing Role: Standby-mode voltage clamp that remains non-conductive until transient exceeds 40 V, minimizing leakage impact on signal integrity. Use Value: Maintains <5 µA leakage at 36 V, ensuring compatibility with high-impedance PLC input sensing circuits. |
| DC Power Supplies | Renewable Energy Inverters |
Use Scenario: Secondary-side overvoltage protection on 36 V auxiliary supply rails feeding isolated gate drivers and sensors. IC Role / Device Role / Timing Role: Fast-reacting shunt element that diverts surge energy away from downstream LDOs and optocouplers. Use Value: Withstands 300 W surge for 1 ms, enabling compliance with EN 61000-4-5 surge immunity testing at ±2 kV. | Use Scenario: Protection of battery management system (BMS) communication lines exposed to solar array ground potential shifts and lightning coupling. IC Role / Device Role / Timing Role: Bidirectional-capable suppression when paired with complementary device; standalone operation provides unidirectional rail-to-ground clamping. Use Value: Junction capacitance of 390 pF at 0 V allows use on CAN or RS-485 lines up to 1 Mbps without signal distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | Higher clamping voltage (64.3 V @ 5.3 A), lower surge rating (600 W vs. 300 W), same DO-214AA package | Designed for higher-energy IEC 61000-4-5 Level 5 testing; less margin below 40 V IC absolute maximum ratings | Select SMBJ36A only if system requires >600 W single-pulse capability and can tolerate 3.6 V higher clamping voltage. |
| P6SMB36A | Identical electrical specs but rated for 600 W surge; larger DO-214AA package with different thermal pad geometry | Requires PCB footprint revision; offers extended thermal time constant for repetitive surges | Choose P6SMB36A when board layout allows DO-214AA and thermal management demands longer surge duration support. |
Compared with SMBJ36A and P6SMB36A, the BZG04-36TR3 delivers tighter clamping (60.7 V), lower junction capacitance (390 pF), and optimized thermal interface for DO-214AC footprints - making it preferred for space-constrained 36 V rail protection where precision voltage limiting and signal-line compatibility are critical.

FAQ
What is the Zener breakdown voltage tolerance for BZG04-36TR3?
The BZG04-36TR3 has a Zener breakdown voltage of 40 V minimum and no maximum specified in the datasheet; typical value is 42 V at 10 mA test current. This reflects its design as a precision clamping device rather than a voltage reference, where upper bound is intentionally omitted to prioritize surge robustness over tight regulation.
Does BZG04-36TR3 support bidirectional transient suppression?
No, the BZG04-36TR3 is a unidirectional Zener diode configured for cathode-to-anode clamping only. For bidirectional protection, two BZG04-36TR3 devices must be connected in series opposition, or a dedicated bidirectional TVS such as SMAJ36CA should be selected instead.
What is the maximum continuous power dissipation for BZG04-36TR3 at 70 °C ambient?
At 70 °C ambient, the BZG04-36TR3's maximum continuous power dissipation is derated from 3 W (at 100 °C with RthJA < 25 K/W) to approximately 2.1 W, calculated using linear derating from the 150 °C junction limit and RthJA = 125 K/W on standard epoxy-glass PCB layout per Figure 1b.
Can BZG04-36TR3 be used in automotive applications?
Yes, the BZG04-36TR3 meets AEC-Q200 stress test requirements for passive components and is qualified for under-hood temperatures up to 125 °C ambient. Its 150 °C junction limit, glass passivation, and RoHS compliance make it suitable for 12 V/24 V/36 V automotive subsystems including body control modules and ADAS power domains.
What does the "TR3" suffix indicate in BZG04-36TR3?
The "TR3" suffix denotes tape-and-reel packaging in 6 k unit quantities on 13-inch reels, with internal box packaging. This differs from "TR", which indicates 1.5 k units on 7-inch reels. Both are compatible with standard SMT pick-and-place equipment using standard SMC carrier tape dimensions.
