Product details
Overview
BZG04-200TR from Vishay Semiconductors is a glass-passivated, surface-mount Zener diode optimized for high-energy transient voltage suppression in power rails and signal lines. It features a 200 V standoff voltage (VR), 228 V minimum breakdown voltage at 2 mA (V(BR)), 336 V clamping voltage at 0.9 A (VCL), 300 W non-repetitive surge power rating (PZSM), and DO-214AC package for industrial-grade reliability.
For engineers reviewing the BZG04-200TR datasheet, BZG04-200TR pinout, BZG04-200TR application, or BZG04-200TR equivalent, this device is selected for overvoltage protection where fast response (≤1 ps), low junction capacitance (122 pF), and high surge current tolerance (50 A IFSM) are critical in DC power supplies, telecom interfaces, and automotive control modules.
Technical Context
The BZG04-200TR operates as a unidirectional voltage-clamping device with a precisely defined Zener breakdown threshold and tightly controlled dynamic impedance. Its glass-passivated junction ensures stable leakage current (IR ≤ 5 µA at VR = 200 V) and long-term parameter stability under thermal cycling.
Designed for transient suppression per IEC 61000-4-5 (10/1000 µs waveform), it delivers 300 W peak surge power dissipation with minimal voltage overshoot due to low clamping ratio (VCL/V(BR) ≈ 1.47) and sub-nanosecond response time, enabling robust protection without sacrificing system speed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VR) | 200 V - Maximum reverse voltage before significant conduction begins; defines operating margin before clamping activation. |
| Breakdown Voltage (V(BR)) | 228 V min @ 2 mA - Guaranteed minimum Zener voltage at test current; sets lower bound for clamping onset. |
| Clamping Voltage (VCL) | 336 V @ 0.9 A - Peak voltage seen across device during 10/1000 µs surge; determines protected circuit's maximum stress level. |
| Surge Power (PZSM) | 300 W - Non-repetitive peak power handling capability; enables survival of high-energy lightning-induced transients. |
| Junction Capacitance (Cj) | 122 pF @ 0 V - Low capacitance minimizes signal distortion and loading on high-speed data lines or RF circuits. |
| Surge Current (IFSM) | 50 A - Peak forward surge current tolerance; supports robustness against accidental polarity reversal or inrush events. |
| Thermal Resistance (RthJA) | 100–150 K/W - Depends on PCB mounting; dictates derating curve and maximum continuous power (1.25–3 W) at ambient temperatures. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, molded plastic case with axial leads trimmed and formed for gull-wing mounting. Approximate weight: 77 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Marked Band) | High-impedance reference node | Connected to protected line; conducts when voltage exceeds V(BR); defines polarity-sensitive clamping direction. |
| Anode | Return path / ground reference | Typically tied to system ground or low-impedance return; completes clamping current path during transient events. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable leakage current (<5 µA) and resistance to humidity-induced parameter drift over 10+ year field life. |
| Fast response time | ≤1 ps rise time enables clamping before sensitive downstream ICs experience damaging overvoltage. |
| Low clamping ratio | VCL/V(BR) ≈ 1.47 reduces voltage overshoot during surges, lowering stress on protected MOSFETs or microcontrollers. |
| RoHS-compliant & lead-free | Meets EU Directive 2002/95/EC; compatible with standard Pb-free reflow profiles without solder joint reliability degradation. |
Applications
| Industrial DC Power Supply Protection | Telecom Line Interface Protection |
|---|---|
Use Scenario: 24 V/48 V industrial PLC power input subjected to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Primary shunt clamping element placed across input rail to clamp surges to safe levels before they reach DC-DC converters. Use Value: Withstands 300 W surges and clamps to 336 V, preventing damage to upstream rectifiers and downstream regulators rated for ≤400 V. |
Use Scenario: RS-485 data line exposed to ESD and lightning-induced common-mode surges in outdoor base stations. IC Role / Device Role / Timing Role: Bidirectional protection pair (with complementary device) limiting differential and common-mode overvoltage on twisted-pair lines. Use Value: 122 pF capacitance avoids signal integrity loss at 10 Mbps; 50 A IFSM handles multi-kV EFT bursts without degradation. |
| Automotive Body Control Module | Renewable Energy Inverter DC Link |
Use Scenario: 12 V battery-supplied BCM experiencing ISO 7637-2 pulse 5a (load dump up to 60 V). IC Role / Device Role / Timing Role: Standoff-rated Zener placed between battery rail and regulator input to absorb energy beyond TVS diode capability. Use Value: 200 V VR provides margin above nominal 12 V + load dump; 300 W PZSM sustains multiple pulses without thermal runaway. |
Use Scenario: 400 V DC link in solar inverter subject to switching transients and grid fault recovery spikes. IC Role / Device Role / Timing Role: Secondary clamping stage parallel to main MOV, providing precise voltage limit and faster response than bulk varistors. Use Value: Tight V(BR) tolerance (228 V min) ensures predictable clamping at 336 V, protecting IGBT gate drivers from overvoltage stress. |
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 |
|---|---|---|---|
| SMBJ200A | TVS diode (AEC-Q101 qualified), 200 V standoff, 328 V clamping @ 1.2 A, 600 W Ppp, higher capacitance (170 pF) | Designed for automotive-grade repetitive surge immunity; requires tighter layout for thermal management | Select SMBJ200A when AEC-Q101 qualification and higher average power handling are required; not drop-in due to different VCL and thermal profile. |
| P6KE200A | Through-hole DO-15 package, 200 V standoff, 324 V clamping @ 1.2 A, 600 W Ppp, slower response (~1 ns) | Legacy design compatibility; unsuitable for high-density SMT layouts or automated assembly | Choose P6KE200A only for through-hole prototyping or legacy board refresh; BZG04-200TR offers superior SMT reliability and smaller footprint. |
Compared with SMBJ200A and P6KE200A, the BZG04-200TR delivers lower clamping voltage (336 V vs. ≥324 V), faster response (≤1 ps vs. ~1 ns), and DO-214AC SMT compatibility-making it optimal for space-constrained, high-reliability industrial and telecom designs where precise voltage limiting and rapid transient capture are essential.

FAQ
What is the maximum continuous power dissipation for BZG04-200TR at 50 °C ambient?
The BZG04-200TR supports 1.25 W continuous power dissipation when mounted on epoxy-glass hard tissue with RthJA = 100 K/W and ambient temperature of 50 °C. This value assumes proper PCB copper area and thermal vias; exceeding this rating risks junction temperature exceeding 150 °C and permanent degradation. Always verify thermal design using the BZG04-200TR's published RthJA curves and actual board layout.
Does BZG04-200TR meet RoHS and lead-free soldering requirements?
Yes, the BZG04-200TR is lead (Pb)-free and compliant with RoHS Directive 2002/95/EC and WEEE 2002/96/EC. It is qualified for standard Pb-free reflow profiles (peak temperature ≤ 260 °C, 10-second dwell), and its glass-passivated construction prevents intermetallic formation or solder joint embrittlement during repeated thermal cycles.
What is the typical junction capacitance of BZG04-200TR and how does it affect high-speed signal lines?
The BZG04-200TR has a typical junction capacitance of 122 pF at 0 V bias. At 1 MHz, this value remains stable and introduces minimal loading on signal lines operating below 10 Mbps. For higher-speed interfaces (e.g., USB 2.0 or CAN FD), designers should verify eye diagram integrity and consider series impedance matching to mitigate capacitive coupling effects introduced by the BZG04-200TR.
Can BZG04-200TR be used in bidirectional transient protection configurations?
No, the BZG04-200TR is a unidirectional Zener diode and conducts only in reverse breakdown. For bidirectional protection (e.g., RS-485 or AC lines), two BZG04-200TR devices must be connected in series opposition (anode-to-anode), or a dedicated bidirectional TVS like SMBJ200CA should be selected. Using a single BZG04-200TR in AC applications risks forward conduction and failure.
How does the 300 W surge rating of BZG04-200TR relate to real-world IEC 61000-4-5 testing?
The 300 W non-repetitive surge power rating (PZSM) of the BZG04-200TR corresponds to a 10/1000 µs waveform with peak current of 0.9 A delivering 336 V clamping. This meets Level 4 (4 kV) IEC 61000-4-5 common-mode surge testing when properly mounted on adequate copper area. Multiple surges require thermal recovery time; the BZG04-200TR is not rated for repetitive operation at full PZSM.
