Product details
Overview
BZG04-22TR3 from Vishay Semiconductors is a glass-passivated Zener diode designed for transient voltage suppression in power rails and signal lines, with a nominal Zener breakdown voltage of 25.1 V at 25 mA, clamping voltage of 38.1 V at 7.9 A (10/1000 µs pulse), and surge power rating of 300 W. It operates within -65 °C to +150 °C and is qualified for industrial overvoltage protection applications.
For engineers reviewing the BZG04-22TR3 datasheet, BZG04-22TR3 pinout, BZG04-22TR3 application, or BZG04-22TR3 equivalent, key selection criteria include its DO-214AC package, 22 V standoff voltage, 300 W non-repetitive surge capability, low junction-to-lead thermal resistance (25 K/W), and RoHS-compliant lead-free construction.
Technical Context
The BZG04-22TR3 functions as a unidirectional voltage-clamping device with fast response time (≤1 ps), leveraging a glass-passivated PN junction to ensure stable breakdown behavior under repetitive transients. Its thermal design supports mounting on epoxy-glass PCBs (RthJA = 125 K/W) or Al₂O₃ ceramic substrates (RthJA = 100 K/W).
It delivers precise regulation across temperature via a specified TKVZ of +0.06 %/K and maintains low junction capacitance (545 pF at 0 V, 1 MHz), enabling effective high-speed transient suppression without signal distortion in DC power and analog interface circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VR) | 22 V - Maximum reverse voltage before significant conduction begins; defines operating margin below clamping threshold. |
| Zener Breakdown Voltage (V(BR)) | 25.1 V min @ 25 mA - Precise regulation point ensuring predictable clamping onset in overvoltage events. |
| Clamping Voltage (VCL) | 38.1 V max @ 7.9 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; critical for IC survivability. |
| Non-repetitive Surge Power (PZSM) | 300 W - Energy-handling capacity for short-duration transients such as ESD or lightning-induced surges. |
| Junction-to-Lead Thermal Resistance | 25 K/W - Enables efficient heat transfer to PCB copper, supporting sustained operation under intermittent overload. |
| Junction Capacitance (Cj) | 545 pF @ 0 V, 1 MHz - Low enough to avoid loading high-impedance analog nodes while maintaining robust ESD immunity. |
| Surge Current Rating (IPP) | 7.9 A - Peak current the device safely shunts during standardized 10/1000 µs surge waveform. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, plastic-molded case with cathode band marking; weight ≈ 77 mg.
| Pin/Terminal | Circuit Role | Design Meaning |

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 |
|---|---|---|---|
| SMBJ24A | Higher clamping voltage (38.9 V), same DO-214AA package, lower surge current (7.3 A) | Designed for higher-energy IEC 61000-4-5 Level 4 testing; less precise regulation (±5 % vs ±2.5 %) | Prefer when surge energy exceeds 300 W or when standard TVS performance suffices over precision Zener behavior. |
| 1N5355B | Same 24 V nominal Zener, axial DO-41 package, lower PZSM (150 W), higher RthJA (200 K/W) | Limited to low-power, through-hole designs; unsuitable for automated SMT assembly or high-density layouts. | Select only for legacy board rework or cost-sensitive prototypes where SMT footprint and thermal performance are secondary. |
Compared with SMBJ24A and 1N5355B, the BZG04-22TR3 offers superior voltage regulation accuracy, faster response, and optimized thermal performance in DO-214AC - making it preferred for space-constrained, high-reliability industrial and automotive applications requiring repeatable clamping behavior.

Does BZG04-22TR3 meet RoHS and lead-free requirements?
Yes, the BZG04-22TR3 is a lead-free component compliant with RoHS Directive 2002/95/EC and WEEE Directive 2002/96/EC. Vishay confirms no ozone-depleting substances were used in its manufacture, and the device is rated for standard Pb-free reflow profiles up to 260 °C peak temperature.
What is the maximum clamping voltage of BZG04-22TR3 under surge conditions?
The BZG04-22TR3 exhibits a maximum clamping voltage of 38.1 V when subjected to a 10/1000 µs surge pulse at 7.9 A peak current. This value is measured at Tj = 25 °C and defines the upper voltage limit imposed on protected circuitry during standardized transient events.
Can BZG04-22TR3 be used in place of BZG04-22TR?
Yes, BZG04-22TR3 is functionally identical to BZG04-22TR except for packaging: TR3 denotes 6 k unit reels on 13-inch tapes versus TR's 1.5 k on 7-inch reels. Electrical, thermal, and mechanical specifications are fully interchangeable; no design or layout changes are required when substituting BZG04-22TR3 for BZG04-22TR.
What thermal resistance values apply to BZG04-22TR3 in PCB mounting?
The BZG04-22TR3 has a junction-to-ambient thermal resistance (RthJA) of 125 K/W when mounted on epoxy-glass PCB per Figure 1b, and 100 K/W on Al₂O₃ ceramic substrate. Its junction-to-lead resistance is fixed at 25 K/W, enabling accurate thermal modeling for power dissipation up to 1.25 W at 50 °C ambient.
