Product details
Overview
BZG04-160TR 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 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 with 150 °C junction temperature rating - deployed in industrial power supply overvoltage protection circuits.
For engineers reviewing the BZG04-160TR datasheet, BZG04-160TR pinout, BZG04-160TR application, or BZG04-160TR equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, surge current handling under 10/1000 µs waveform, thermal resistance to PCB copper area, and RoHS-compliant lead-free construction for automated SMT assembly.
Technical Context
The BZG04-160TR operates as a unidirectional voltage-clamping device with fast response time (≤1 ps), leveraging a glass-passivated PN junction to sustain high-energy transients without degradation. Its thermal design relies on low RthJL (25 K/W) and board-dependent RthJA (100–150 K/W), enabling effective heat dissipation when mounted on Al2O3 ceramic or epoxy-glass substrates.
It delivers precise voltage regulation at IZT = 5 mA with breakdown voltage V(BR) = 188 V (min), exhibits low junction capacitance (135 pF at 0 V), and maintains stable performance across -65 °C to +150 °C storage and operating ranges - critical for automotive and industrial environments where thermal cycling and ESD robustness are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VR) | 160 V - maximum continuous reverse voltage before conduction begins; defines minimum system operating margin. |
| Breakdown Voltage (V(BR)) | 188 V min @ 5 mA - ensures reliable clamping onset above nominal rail voltage. |
| Clamping Voltage (VCL) | 276 V @ 1.1 A (10/1000 µs) - limits peak transient voltage seen by downstream circuitry. |
| Surge Power Rating (PZSM) | 300 W - supports single high-energy lightning-induced surges per IEC 61000-4-5 Level 4. |
| Junction Capacitance (Cj) | 135 pF @ 0 V, 1 MHz - low enough to avoid signal integrity issues on <10 MHz analog/sensor lines. |
| Thermal Resistance (RthJA) | 100–150 K/W - depends on PCB copper area; requires ≥1 cm² 2-oz copper pour for full 3 W steady-state dissipation. |
| Package | DO-214AC (SMA) - industry-standard surface-mount outline compatible with JEDEC MS-013, supports reflow soldering. |
Pinout & Package
DO-214AC (SMA) package: molded plastic body with axial leads trimmed and formed for surface mounting; cathode indicated by band; typical weight 77 mg; compliant with RoHS 2002/95/EC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse bias reference | Connected to lower-potential node (e.g., GND or return path); establishes polarity for unidirectional clamping. |
| Cathode | Zener voltage reference / Surge current sink | Connected to protected line (e.g., 160 V rail); conducts surge current to ground during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable long-term Zener voltage tolerance (<±5 %) and immunity to humidity-induced leakage drift. |
| Fast response time ≤1 ps | Clamps ESD and fast-rising transients before sensitive ICs experience latch-up or gate oxide damage. |
| Lead (Pb)-free & RoHS-compliant | Meets global environmental regulations and supports lead-free reflow profiles (JEDEC J-STD-020). |
| High surge current capability (50 A IFSM) | Withstands repetitive 10 ms half-sine surges common in motor drive and relay switching noise environments. |
Applications

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 |
|---|---|---|---|
| SMBJ160A | Higher clamping voltage (259 V @ 1.2 A), larger SMB package (DO-214AA), 600 W PPP rating | Better suited for higher-energy surges but less precise voltage thresholding due to wider VBR tolerance (±5 % vs. BZG04-160TR's tighter distribution) | Select SMBJ160A when surge energy exceeds 300 W and PCB space allows larger footprint. |
| P6SMB160A | Same DO-214AA package, identical 160 V standoff, but slower response (>1 ns) and higher Cj (180 pF) | Acceptable for lower-speed power rails but unsuitable for signal-line protection near high-frequency interfaces | Choose P6SMB160A only if cost sensitivity outweighs need for sub-nanosecond response and minimal capacitance. |
Compared with SMBJ160A and P6SMB160A, the BZG04-160TR offers superior voltage precision, faster transient response, and lower junction capacitance - making it optimal for applications demanding tight clamping margins and signal integrity preservation, especially in compact DO-214AC layouts.

FAQ
What is the maximum clamping voltage of the BZG04-160TR under standard test conditions?
The BZG04-160TR has a maximum clamping voltage of 276 V when subjected to a 10/1000 µs surge pulse at 1.1 A peak current, as specified in the Vishay BZG04-Series datasheet (Doc. #85594, Rev. 2.2). This value ensures predictable overvoltage limiting for downstream components rated up to 300 V, and is measured with the device mounted on an Al2O3 ceramic substrate per Figure 1b.
Does the BZG04-160TR support lead-free reflow soldering processes?
Yes, the BZG04-160TR is lead (Pb)-free and fully compliant with RoHS 2002/95/EC, meeting JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for surface-mount assembly. Its glass-passivated structure remains stable through standard lead-free reflow profiles peaking at 260 °C, and no special pre-bake or handling is required prior to soldering.
How does the thermal resistance of the BZG04-160TR vary with PCB layout?
The BZG04-160TR's junction-to-ambient thermal resistance (RthJA) ranges from 100 K/W (on Al2O3 ceramic) to 150 K/W (on standard epoxy-glass PCB), depending on copper area and thickness. For reliable 3 W continuous operation, a minimum 1 cm² 2-oz copper pour connected directly to both leads is required - verified in Vishay's thermal characterization (Fig. 2 and Table "Thermal Characteristics").
Can the BZG04-160TR be used in bidirectional transient suppression configurations?
No, the BZG04-160TR is a unidirectional Zener diode optimized for reverse-bias clamping only. It lacks symmetrical breakdown characteristics and is not rated for forward conduction beyond its specified 1.2 V forward voltage at 0.5 A. For bidirectional protection, two BZG04-160TR devices must be connected in series opposition, or a dedicated bidirectional TVS such as SMAJ160A should be selected instead.
What is the junction capacitance of the BZG04-160TR and how does it affect high-frequency signal lines?
The BZG04-160TR exhibits 135 pF junction capacitance at 0 V and 1 MHz, as measured per the BZG04-Series datasheet. This low capacitance enables use on signal lines up to ~10 MHz without significant attenuation or phase shift - making it suitable for clamping transients on sensor inputs, analog monitoring paths, or low-speed communication buses adjacent to 160 V power domains.
