Product details
Overview
BZG04-180TR3 from Vishay Semiconductors is a glass-passivated, high-reliability Zener diode designed for transient voltage suppression in power rails and signal lines. It features a 180 V standoff voltage, 305 V clamping voltage at 1 A surge current, 300 W non-repetitive peak surge power rating, and DO-214AC (SMA) package - used in industrial power supply overvoltage protection circuits.
For engineers reviewing the BZG04-180TR3 datasheet, BZG04-180TR3 pinout, BZG04-180TR3 application, or BZG04-180TR3 equivalent, key selection criteria include clamping voltage margin vs. system rail, surge current handling under 10/1000 µs waveform, thermal resistance to PCB pad layout, junction temperature limit of 150 °C, and RoHS-compliant lead-free construction.
Technical Context
The BZG04-180TR3 operates as a unidirectional voltage clamp with precise breakdown at 208 V (min) and 228 V (max) at 2 mA test current. Its fast response time (≤ 1 ps) enables effective suppression of ESD and lightning-induced transients before downstream IC damage occurs.
Thermal design relies on low junction-to-lead resistance (25 K/W) and mounting-dependent junction-to-ambient resistance (100–150 K/W), requiring copper pour optimization per Vishay's Fig. 1a/1b layouts. The device sustains 50 A peak forward surge current for 10 ms half-sine wave without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VR) | 180 V - maximum continuous reverse voltage before significant leakage; sets operating margin below clamping threshold |
| Breakdown Voltage (V(BR)) | 208 V min / 228 V max @ 2 mA - defines precise conduction onset for predictable clamping behavior |
| Clamping Voltage (VCL) | 305 V @ 1 A (10/1000 µs) - peak voltage seen by protected circuit during rated surge event |
| Peak Surge Power (PZSM) | 300 W - maximum single-pulse energy dissipation capability without failure |
| Junction Temperature (Tj) | 150 °C - absolute maximum operating temperature; dictates derating above 25 °C ambient |
| Package | DO-214AC (SMA) - surface-mount outline with 77 mg mass and standardized footprint for automated assembly |
| Surge Current (IPP) | 1 A (10/1000 µs) - standardized test condition defining clamping voltage; correlates to real-world transient severity |
Pinout & Package
DO-214AC (SMA) package: molded epoxy body, axial leads trimmed and formed for surface-mount placement; cathode band marked on body; standard JEDEC MS-013 variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry during forward conduction or surge shunting | Connected to lower-potential node (e.g., GND or return path); must handle 50 A surge current |
| Cathode | Current exit during reverse-biased clamping | Connected to protected line (e.g., 180 V rail); carries full transient current to ground reference |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable Zener characteristics and long-term reliability under thermal cycling and humidity stress |
| Fast response time ≤ 1 ps | Ensures clamping activation before nanosecond-scale ESD events propagate into sensitive logic |
| 300 W peak surge power | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly mounted on thermal pads |
| Lead (Pb)-free & RoHS compliant | Fulfills EU Directive 2002/95/EC requirements for environmentally restricted substances in electronics |
| DO-214AC mechanical robustness | Withstands reflow soldering profiles up to 260 °C and board flexure in industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A | Higher clamping voltage (324 V @ 1 A), higher Ppp (600 W), same DO-214AA package but larger footprint | Designed for higher-energy transients; less precise voltage regulation due to wider V(BR) tolerance | Select when surge energy exceeds 300 W and PCB space permits larger SMB package |
| P6SMB180A | Same clamping (324 V @ 1 A), same Ppp (600 W), identical DO-214AA footprint but different thermal resistance (RthJA = 110 K/W) | Optimized for lower-cost consumer applications; reduced surge cycle life vs. BZG04-series glass passivation | Choose for cost-sensitive designs where 150 °C Tj rating and long-term stability are secondary to unit price |
Compared with SMBJ180A and P6SMB180A, the BZG04-180TR3 delivers tighter voltage tolerance (208–228 V vs. 180–200 V), lower clamping voltage (305 V vs. 324 V), and superior long-term reliability via glass passivation - making it preferred for industrial and transportation systems requiring field longevity.

FAQ
What is the exact breakdown voltage range for BZG04-180TR3?
The BZG04-180TR3 has a specified breakdown voltage range of 208 V minimum to 228 V maximum at 2 mA test current, measured per Vishay Document 85594 Rev. 2.2. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable overvoltage margin design in 180 V systems. The BZG04-180TR3 achieves this via glass-passivated junction processing, which stabilizes V(BR) against thermal drift and aging effects.
Does BZG04-180TR3 support bidirectional transient suppression?
No, the BZG04-180TR3 is a unidirectional Zener diode intended for reverse-biased clamping only. It conducts during positive transients on the cathode relative to anode and blocks in forward direction up to 1.2 V. For bidirectional protection, two BZG04-180TR3 devices must be connected in series opposition, or a dedicated bidirectional TVS like SMAJ180A should be selected instead of the BZG04-180TR3.
What is the maximum allowable PCB pad size for optimal thermal performance of BZG04-180TR3?
Vishay specifies thermal resistance values based on defined copper layouts: RthJA = 100 K/W when mounted on Al₂O₃ ceramic, and 125–150 K/W on epoxy-glass PCBs (Fig. 1a/1b). To achieve the 100 K/W rating, use ≥ 1 cm² copper pour per terminal with 2 oz copper thickness and thermal vias to inner ground planes. Exceeding these dimensions yields diminishing returns; the BZG04-180TR3 does not require oversized pads beyond Vishay's documented layouts.
Can BZG04-180TR3 replace BZG04-180TR in a design?
Yes, BZG04-180TR3 is a direct replacement for BZG04-180TR, differing only in packaging: TR denotes 1.5 k per 7-inch reel, while TR3 indicates 6 k per 13-inch reel (6 k/box). Electrical, thermal, and mechanical specifications are identical between BZG04-180TR and BZG04-180TR3. No layout or schematic changes are needed when substituting BZG04-180TR3 for BZG04-180TR in production.
Is BZG04-180TR3 suitable for automotive applications per AEC-Q200?
No, the BZG04-180TR3 is not qualified to AEC-Q200. Vishay documents it for industrial and general-purpose transient suppression only. While its 150 °C junction rating and glass passivation support extended temperature operation, it lacks the stress testing, lot traceability, and failure analysis reporting required for automotive qualification. For AEC-Q200-compliant alternatives, consider Vishay's Automotive Grade SMAJ180A or similar qualified TVS devices instead of the BZG04-180TR3.
