Product details
Overview
BZG04-160TR3 from Vishay Semiconductors is a glass-passivated, high-reliability Zener diode designed for transient voltage suppression in power and signal lines. It features a 160 V standoff voltage, 276 V clamping voltage at 1.1 A peak pulse current, 300 W non-repetitive surge power rating, and DO-214AC (SMA) package. It is used in industrial power supply overvoltage protection circuits where fast response (≤1 ps) and high-energy clamping are required.
For engineers reviewing the BZG04-160TR3 datasheet, BZG04-160TR3 pinout, BZG04-160TR3 application, or BZG04-160TR3 equivalent, key selection criteria include clamping voltage margin vs. system rail, surge current capability under 10/1000 µs waveform, thermal resistance to PCB layout, junction temperature limit (150 °C), and RoHS-compliant lead-free construction.
Technical Context
The BZG04-160TR3 operates as a unidirectional voltage clamp with precise breakdown at 188 V (min) and 208 V (max) at 5 mA test current. Its glass-passivated junction ensures stable leakage (<5 µA at 160 V) and long-term reliability under repeated surge stress.
Thermal design requires attention to mounting: RthJA ranges from 100 K/W (on Al₂O₃ ceramic) to 150 K/W (on epoxy-glass PCB), directly impacting sustained power handling. The device delivers 300 W peak surge power only for 10/1000 µs pulses at Tj = 25 °C - derating applies for higher ambient or repetitive events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VR) | 160 V - maximum continuous reverse voltage before significant conduction begins; defines operating margin below clamping threshold |
| Breakdown Voltage (V(BR)) | 188–208 V @ 5 mA - tight tolerance band ensures predictable turn-on during transients |
| Clamping Voltage (VCL) | 276 V @ 1.1 A (10/1000 µs) - peak voltage seen by protected circuit during rated surge event |
| Peak Surge Power (PZSM) | 300 W - maximum single-pulse energy absorption capability under standardized waveform |
| Junction Temperature (Tj) | 150 °C - absolute maximum operating temperature; limits continuous power dissipation based on PCB thermal design |
| Package | DO-214AC (SMA) - surface-mount outline with 77 mg mass and defined thermal pad requirements per Fig. 1a/b |
| Junction Capacitance (Cj) | 135 pF @ 0 V - affects high-frequency impedance and noise coupling in signal-line protection |
Pinout & Package
DO-214AC (SMA) package: molded plastic body with axial leads trimmed and formed for surface-mount assembly; cathode indicated by band; mounted per Vishay Fig. 1a (epoxy-glass) or Fig. 1b (Al₂O₃ ceramic) for specified RthJA values.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward bias; connected to lower-potential node in clamp configuration | Must be routed with low-inductance path when used in fast transient suppression; not intended for continuous forward conduction |
| Cathode | Current exit point during reverse breakdown; connected to protected line or rail | Marked by band; determines polarity of clamping action - reverse-biased across protected node and ground/rail |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable leakage performance (<5 µA at VR) and resistance to humidity/moisture-induced degradation over lifetime |
| Fast response time | ≤1 ps rise time ensures clamping activation before sensitive downstream components experience overvoltage stress |
| High surge current rating | 50 A peak forward surge current (10 ms half-sine) supports robustness against inrush and fault currents |
| Lead (Pb)-free & RoHS compliant | Meets EU Directive 2002/95/EC; enables use in environmentally regulated industrial and consumer end equipment |
| Controlled thermal resistance | RthJL = 25 K/W and RthJA = 100–150 K/W allows accurate junction temperature prediction based on PCB layout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Same 160 V standoff but bidirectional; 300 W Pppm; DO-214AA (SMB) package; higher Cj (180 pF) | Required where symmetrical AC-line or data-line surges exist; unsuitable for DC-only unidirectional clamping | Select BZG04-160TR3 when unidirectional clamping, lower capacitance, or DO-214AC footprint is mandatory |
| P6SMB160A | Same 160 V standoff, bidirectional, 600 W Pppm, DO-214AA; higher surge rating but larger package and 200 pF Cj | Used where higher single-pulse energy must be absorbed; incompatible with space-constrained SMA layouts | Choose BZG04-160TR3 for compact 77 mg DO-214AC designs needing <140 pF and verified 150 °C Tj operation |
Compared with SMBJ160A and P6SMB160A, the BZG04-160TR3 offers superior high-frequency response due to lower junction capacitance (135 pF), tighter thermal resistance control (RthJL = 25 K/W), and guaranteed unidirectional behavior - critical for DC bus protection where reverse conduction must be avoided.

FAQ
What is the maximum clamping voltage of the BZG04-160TR3 under standard surge conditions?
The BZG04-160TR3 has a maximum clamping voltage of 276 V when subjected to a 10/1000 µs surge pulse at 1.1 A peak current. This value is measured at Tj = 25 °C and defines the upper voltage limit imposed on protected circuitry during a standardized transient event. The BZG04-160TR3 maintains this clamping performance consistently due to its glass-passivated junction and controlled Zener breakdown characteristics.
Is the BZG04-160TR3 suitable for bidirectional transient suppression?
No, the BZG04-160TR3 is a unidirectional Zener diode intended for reverse-bias clamping only. Its electrical specifications - including standoff voltage (160 V), breakdown range (188–208 V), and clamping behavior - are defined exclusively for reverse polarity operation. For bidirectional protection, devices like SMBJ160A must be selected instead of the BZG04-160TR3.
What is the thermal resistance from junction to ambient for the BZG04-160TR3 on a standard PCB?
The BZG04-160TR3 exhibits RthJA = 150 K/W when mounted on epoxy-glass hard tissue PCB per Vishay Figure 1a, and 125 K/W per Figure 1b. On Al₂O₃ ceramic substrate, RthJA improves to 100 K/W. These values directly determine allowable continuous power dissipation - for example, at Tamb = 50 °C and RthJA = 125 K/W, the BZG04-160TR3 supports 1.25 W continuous operation.
Does the BZG04-160TR3 meet RoHS and lead-free requirements?
Yes, the BZG04-160TR3 is lead (Pb)-free and complies with EU RoHS Directive 2002/95/EC and WEEE 2002/96/EC. Vishay confirms that no ozone-depleting substances are used in its manufacture, and the device carries the "e3" marking indicating matte tin termination. This makes the BZG04-160TR3 suitable for environmentally regulated industrial and consumer applications.
How does the junction capacitance of the BZG04-160TR3 affect high-speed signal line protection?
The BZG04-160TR3 has a typical junction capacitance of 135 pF at 0 V, which introduces minimal loading on low-frequency power rails but may impact signal integrity above ~1 MHz. In telecom or data line applications, this capacitance must be evaluated against bandwidth requirements - for instance, at 200 kHz control signaling, the BZG04-160TR3's 135 pF presents >6 kΩ impedance and causes negligible distortion, making it appropriate for such uses.
