Product details
Overview
BZG04-220TR3 from Vishay Semiconductors is a glass-passivated, surface-mount Zener diode designed for high-energy transient voltage suppression in power supply and interface protection circuits. It features a 220 V standoff voltage, 380 V clamping voltage at 0.8 A peak pulse current, 300 W non-repetitive surge power rating, and DO-214AC (SMA) package with lead (Pb)-free construction compliant with RoHS 2002/95/EC.
For engineers reviewing the BZG04-220TR3 datasheet, BZG04-220TR3 pinout, BZG04-220TR3 application, or BZG04-220TR3 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal resistance to PCB layout (RthJA = 100–150 K/W), junction temperature limit of 150 °C, and compatibility with automated SMT assembly on epoxy-glass or Al₂O₃ substrates.
Technical Context
The BZG04-220TR3 operates as a unidirectional voltage-clamping device with a nominal breakdown voltage of 251 V at 2 mA test current and a temperature coefficient of +0.09 %/K. Its fast response time (≤1 ps) enables effective suppression of ESD and lightning-induced transients before downstream circuitry sustains damage.
It is rated for 50 A peak forward surge current (10 ms half-sine), 3 W steady-state power dissipation at 100 °C ambient (with RthJA < 25 K/W), and exhibits 120 pF junction capacitance at 0 V - making it suitable for DC-biased protection where minimal signal loading is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VR) | 220 V - maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| Breakdown Voltage (V(BR)) | 251 V min @ 2 mA - precise Zener conduction onset for predictable clamping initiation |
| Clamping Voltage (VCL) | 380 V @ 0.8 A (10/1000 µs) - peak voltage seen by protected circuit during surge event |
| Surge Power (PZSM) | 300 W - maximum single-pulse energy absorption capability without failure |
| Junction Capacitance (Cj) | 120 pF @ 0 V, 1 MHz - low enough to avoid signal integrity degradation in DC-coupled lines |
| Thermal Resistance (RthJA) | 100–150 K/W - depends on PCB copper area and substrate; critical for sustained power derating |
| Package | DO-214AC (SMA) - industry-standard SMT outline with 77 mg mass and gull-wing leads |
Pinout & Package
DO-214AC (SMA) package: molded plastic body with cathode band marking; anode and cathode terminals accessible via gull-wing leads; case outline per JEDEC DO-214AC standard; weight ≈ 77 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward bias or surge conduction path | Connected to ground or low-impedance return path; must handle 50 A IFSM surge |
| Cathode | Current exit point during reverse-bias clamping | Connected to protected line; carries full surge current to shunt energy away from load |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable Zener characteristics over temperature and lifetime; prevents moisture-induced parameter drift |
| Fast response time ≤1 ps | Ensures clamping activation prior to propagation of nanosecond-scale ESD events into IC inputs |
| Lead (Pb)-free & RoHS-compliant | Meets global environmental regulations; compatible with standard reflow profiles including Pb-free soldering |
| High reliability design | Validated for operation up to 150 °C junction temperature and 1000+ surge cycles under defined conditions |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A | Same DO-214AA package; 220 V standoff; 360 V clamping @ 1.0 A; 600 W PZSM; higher surge rating but larger footprint | Higher surge capacity suits automotive 12 V systems with stricter ISO 16750-2 requirements | Select SMBJ220A when >300 W single-pulse energy handling is mandatory and board space allows DO-214AA |
| P6SMB220A | DO-214AA package; identical electrical specs but lower production volume; longer lead times; no TR3 packaging option | Limited availability in 6 k reel format; not recommended for high-volume SMT production | Choose BZG04-220TR3 for consistent TR3 (6 k/reel) supply and Vishay's long-term manufacturing commitment |
Compared with SMBJ220A and P6SMB220A, the BZG04-220TR3 offers optimized thermal performance on Al₂O₃ substrates (RthJA = 100 K/W), tighter V(BR) tolerance (251 V min vs. typical 242 V), and guaranteed TR3 packaging for automated placement-making it preferred for industrial power modules requiring thermal stability and supply chain continuity.

FAQ
What is the maximum clamping voltage of the BZG04-220TR3 under standardized surge conditions?
The BZG04-220TR3 has a maximum clamping voltage of 380 V when subjected to a 10/1000 µs surge waveform at a peak current of 0.8 A. This value is measured per IEC 61000-4-5 and defines the highest voltage the protected circuit will experience during such a transient. The BZG04-220TR3 maintains this clamping performance consistently due to its glass-passivated junction and tight V(BR) distribution.
Is the BZG04-220TR3 suitable for bidirectional transient suppression?
No, the BZG04-220TR3 is a unidirectional Zener diode intended for DC-biased protection only. It conducts in reverse breakdown above 251 V but blocks only up to 220 V in forward direction. For AC or bidirectional line protection, a paired configuration or dedicated bidirectional TVS like SMAJ220CA is required. The BZG04-220TR3 datasheet explicitly specifies unidirectional operation.
What PCB layout considerations improve thermal performance of the BZG04-220TR3?
To achieve the lowest RthJA of 100 K/W, mount the BZG04-220TR3 on an Al₂O₃ ceramic substrate per Figure 1b in the datasheet, using minimum 10 mm² copper pour per pad. Avoid narrow traces; use thermal vias under pads if multilayer boards are used. The BZG04-220TR3's thermal resistance increases to 150 K/W on standard epoxy-glass FR4 without enhanced copper, directly impacting its 3 W power derating capability.
Does the BZG04-220TR3 meet automotive qualification standards?
The BZG04-220TR3 is not AEC-Q200 qualified, though it meets RoHS and is widely used in automotive body electronics for non-safety-critical functions. Its 150 °C junction rating, 50 A IFSM, and 300 W surge capability align with many ISO 7637-2 Pulse 1/2a/5a requirements-but formal AEC-Q200 testing and certification are not documented for this part number. For AEC-Q200–mandated designs, consider the automotive-grade SMAJ220A.
What is the meaning of "TR3" in the BZG04-220TR3 part number?
The "TR3" suffix in BZG04-220TR3 indicates tape-and-reel packaging in 13-inch reels containing 6,000 units per reel, with internal box packaging. This format is optimized for high-speed SMT pick-and-place machines and supports just-in-time manufacturing. The base part BZG04-220TR uses 7-inch reels (1,500 units), while BZG04-220TR3 ensures extended run time and reduced changeover frequency in volume production of the BZG04-220TR3.
