Product details
Overview
BZG04-200TR3 from Vishay Semiconductors is a glass-passivated, high-reliability Zener diode designed for transient voltage suppression in power and signal lines. It features a 200 V standoff voltage, 336 V clamping voltage at 0.9 A peak pulse current, 300 W non-repetitive surge power rating, and DO-214AC (SMA) package for surface-mount PCB integration in industrial power supply protection.
For engineers reviewing the BZG04-200TR3 datasheet, BZG04-200TR3 pinout, BZG04-200TR3 application, or BZG04-200TR3 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal resistance to PCB layout (RthJA = 125–150 K/W), junction temperature limit (150 °C), and RoHS-compliant lead-free construction.
Technical Context
The BZG04-200TR3 operates as a unidirectional voltage clamp with precise breakdown at 228 V (min) and 251 V (max) under 2 mA test current. Its fast response time (≤1 ps) enables effective suppression of ESD and lightning-induced transients in DC bus and input stage protection circuits.
Thermal design relies on mounting configuration: RthJA varies from 100 K/W (Al₂O₃ ceramic) to 150 K/W (epoxy-glass hard tissue), while RthJL is fixed at 25 K/W. The device sustains 50 A peak forward surge current (10 ms half-sine) and 3 W steady-state dissipation at 100 °C ambient when RthJA < 25 K/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VR) | 200 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold. |
| Breakdown Voltage (V(BR)) | 228–251 V @ 2 mA - Tight tolerance ensures predictable turn-on during overvoltage events. |
| Clamping Voltage (VCL) | 336 V @ 0.9 A (10/1000 µs) - Peak voltage seen by protected circuit during standardized surge. |
| Surge Power (PZSM) | 300 W - Energy-handling capacity for single transient events without failure. |
| Junction Temp Limit | 150 °C - Maximum allowable die temperature; constrains PCB copper area and airflow requirements. |
| Package | DO-214AC (SMA) - Standard SMD outline with 77 mg mass; compatible with reflow soldering per J-STD-020. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Higher clamping voltage (324 V @ 1.0 A), same DO-214AA package but 10 % lower surge power (200 W vs. 300 W). | Lower energy handling limits use in high-dV/dt inverter DC links where BZG04-200TR3's 300 W rating provides margin. | Select BZG04-200TR3 when 300 W surge capability and tighter V(BR) tolerance (228–251 V) are required for critical industrial systems. |
| P6SMB200A | Same 200 V standoff, but higher clamping (328 V @ 1.0 A) and lower IFSM (40 A vs. 50 A); DO-214AA package with identical footprint but different thermal profile. | Less suitable for automotive load dump where 50 A surge current must be sustained without degradation. | Prefer BZG04-200TR3 for applications demanding full 50 A IFSM and validated 150 °C junction operation under repeated surge stress. |
Compared with SMBJ200A and P6SMB200A, the BZG04-200TR3 delivers superior surge energy absorption (300 W), higher surge current endurance (50 A), and tighter breakdown voltage control-making it preferred for mission-critical industrial and automotive transient suppression where thermal margin and clamping consistency are design-critical.

FAQ
What is the maximum clamping voltage of the BZG04-200TR3 under standard IEC 61000-4-5 test conditions?
The BZG04-200TR3 has a maximum clamping voltage of 336 V when subjected to a 10/1000 µs surge pulse at 0.9 A peak current, as specified in the Vishay BZG04-Series datasheet (Doc. 85594, Rev. 2.2). This value reflects actual measured performance under standardized transient conditions and defines the upper voltage limit imposed on protected circuitry during surge events. Engineers must verify layout parasitics do not elevate this clamping level in final implementation.
Does the BZG04-200TR3 meet RoHS and lead-free soldering requirements?
Yes, the BZG04-200TR3 is explicitly certified as lead (Pb)-free and compliant with RoHS Directive 2002/95/EC and WEEE 2002/96/EC per Vishay documentation. It supports standard Pb-free reflow profiles (J-STD-020), with a maximum peak temperature of 260 °C. The device contains no ozone-depleting substances and is manufactured in accordance with Vishay's ODS elimination policy.
What is the thermal resistance from junction to ambient (RthJA) for the BZG04-200TR3 in typical PCB mounting?
The BZG04-200TR3 exhibits RthJA = 125 K/W when mounted on epoxy-glass hard tissue per Figure 1b in the datasheet, and 150 K/W on Figure 1a layout. These values assume defined copper pad dimensions and are critical for calculating junction temperature rise under steady-state power dissipation. For high-reliability designs, thermal simulation using these published RthJA values is recommended to ensure Tj remains ≤150 °C.
Can the BZG04-200TR3 be used in bidirectional transient protection configurations?
No, the BZG04-200TR3 is a unidirectional Zener diode intended for DC line protection only. It conducts in reverse breakdown above 200 V and forward above ~1.2 V, making it unsuitable for AC or bipolar surge suppression without external series components. For bidirectional protection, a dedicated bidirectional TVS like SMAJ200A or paired unidirectional devices are required-not the BZG04-200TR3 alone.
What is the minimum and maximum breakdown voltage specification for the BZG04-200TR3 at 2 mA test current?
The BZG04-200TR3 has a guaranteed breakdown voltage range of 228 V (minimum) to 251 V (maximum) at 2 mA test current, as documented in the Electrical Characteristics table of Vishay's BZG04-Series datasheet. This ±10 % tolerance band ensures consistent clamping behavior across production lots and supports reliable system-level overvoltage margining in safety-critical applications.
