Product details
Overview
BZG04-62TR3 from Vishay Semiconductors is a glass-passivated, surface-mount Zener diode designed for transient voltage suppression in high-energy surge environments. It features a nominal Zener breakdown voltage of 70 V at 10 mA, clamps transients to ≤103.5 V at 2.9 A peak pulse current, and delivers 300 W non-repetitive surge power handling with ≤1 ps response time. It is used in DC power rail protection for industrial motor drives.
For engineers reviewing the BZG04-62TR3 datasheet, BZG04-62TR3 pinout, BZG04-62TR3 application, or BZG04-62TR3 equivalent, key selection criteria include its DO-214AC package thermal resistance (100 K/W on Al₂O₃), 150 °C junction rating, and verified clamping performance under 10/1000 µs surge pulses.
Technical Context
The BZG04-62TR3 operates as a unidirectional voltage clamp, leveraging a glass-passivated PN junction to maintain stable reverse breakdown behavior across temperature. Its thermal design supports mounting on Al₂O₃ ceramic substrates for optimal RthJA = 100 K/W, enabling sustained 1.25 W dissipation at 50 °C ambient when properly heatsinked.
It exhibits low junction capacitance (280 pF at 0 V) and fast transient response (≤1 ps), making it suitable for protecting sensitive analog inputs and digital I/O lines against ESD and lightning-induced surges without signal distortion or timing skew.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 70 V min / 70 V typ at IZT = 10 mA - defines precise clamping threshold for overvoltage events |
| Clamping Voltage (VCL) | ≤103.5 V at IPP = 2.9 A - ensures protected circuitry remains below safe operating limits during surge |
| Surge Power (PZSM) | 300 W at tp = 10/1000 µs - enables single-event suppression of high-energy transients without failure |
| Junction Temp (Tj) | 150 °C max - allows operation in high-ambient industrial enclosures with margin |
| Package | DO-214AC (SMA) - industry-standard SMD footprint compatible with automated assembly and thermal pad routing |
| Surge Current (IFSM) | 50 A peak forward surge - supports robust handling of asymmetrical fault currents in rectifier-fed systems |
Pinout & Package
Package: DO-214AC (SMA), molded plastic case with axial leads trimmed and formed for surface-mount use; approx. 77 mg mass; RoHS-compliant, lead-free construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward conduction path / surge return node | Connected to ground or low-impedance return path during clamping; must be routed with low-inductance trace |
| Cathode (K) | Zener reference terminal / high-side connection | Connected to protected line; reverse-biased operation establishes clamping voltage relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable long-term Zener voltage tolerance (<±5%) and immunity to humidity-induced parameter drift |
| Fast response time ≤1 ps | Prevents overshoot beyond clamping threshold during nanosecond-scale ESD events |
| 100 K/W RthJA on Al₂O₃ | Supports 1.25 W continuous dissipation at 50 °C ambient without external heatsink |
| Lead (Pb)-free & RoHS compliant | Fulfills EU Directive 2002/95/EC and WEEE 2002/96/EC requirements for commercial and industrial equipment |
Applications
| Industrial Motor Drive Protection | DC Power Supply Input Clamping |
|---|---|
Use Scenario: Suppresses switching transients induced by IGBT turn-off in 48 V–400 V motor control inverters. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed across DC bus rails. Use Value: Limits bus overvoltage to ≤103.5 V during 2.9 A surge, preventing gate driver IC damage and MOSFET avalanche failure. | Use Scenario: Protects input stage of isolated DC/DC converters from load-dump spikes in automotive auxiliary supplies. IC Role / Device Role / Timing Role: Standoff-clamp device connected between VIN and GND, activated only during overvoltage events. Use Value: Withstands 300 W surge energy per event while maintaining <280 pF capacitance to avoid filtering interference on 100 kHz–1 MHz switching nodes. |
| Programmable Logic Controller I/O Protection | Telecom Line Interface Surge Suppression |
Use Scenario: Shields 24 V digital input channels in PLC backplanes from field-wiring induced surges. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp on each input channel, paired with series current-limiting resistor. Use Value: 280 pF junction capacitance avoids signal rise-time degradation on 10 kHz–100 kHz discrete input signals. | Use Scenario: Guards RS-485 transceiver data lines against induced surges in outdoor telecom cabinets. IC Role / Device Role / Timing Role: Bidirectional protection achieved via back-to-back configuration (two BZG04-62TR3 devices). Use Value: Matches 70 V standoff with common-mode surge test levels (IEC 61000-4-5 Level 3: 1 kV/42 Ω), ensuring compliance without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | Higher clamping voltage (104 V @ 2.7 A); same DO-214AA package; lower surge rating (600 W vs. 300 W PZSM) | Designed for unidirectional TVS use; lacks specified Zener tolerance or TKVZ coefficient | Select SMBJ64A only when higher surge energy handling is required and tighter VZ tolerance is not critical |
| P6KE68A | Through-hole DO-15 package; higher clamping (115 V @ 2.6 A); lower surge rating (600 W); no thermal resistance spec for SMT layout | Not suitable for automated SMT assembly; requires PCB real estate and wave-solder process | Choose P6KE68A only for legacy through-hole designs where rework cost exceeds redesign effort |
Compared with SMBJ64A and P6KE68A, the BZG04-62TR3 provides tighter Zener voltage control (±5% typical), defined thermal resistance for SMT thermal management, and guaranteed ≤1 ps response-making it preferred for precision clamping in space-constrained industrial SMT layouts.

FAQ
What is the Zener breakdown voltage specification for BZG04-62TR3?
The BZG04-62TR3 has a minimum Zener breakdown voltage of 70 V at test current IZT = 10 mA, with typical value also 70 V and maximum 70 V per Vishay Document 85594 Rev. 2.2. This tight tolerance supports predictable clamping behavior in precision protection circuits where overvoltage thresholds must remain within narrow margins.
Does BZG04-62TR3 support bidirectional transient suppression?
No, the BZG04-62TR3 is a unidirectional Zener diode. For bidirectional protection, two BZG04-62TR3 devices must be connected in series opposition (anode-to-anode or cathode-to-cathode), as confirmed in Vishay's application guidance for telecom line interfaces. Its datasheet specifies only reverse-bias clamping characteristics.
What is the maximum continuous power dissipation for BZG04-62TR3 at 50 °C ambient?
The BZG04-62TR3 supports 1.25 W continuous power dissipation at Tamb = 50 °C when mounted on epoxy-glass hard tissue with RthJA = 125 K/W, per Absolute Maximum Ratings table. Derating is required above 50 °C ambient, following the linear thermal curve defined in the datasheet.
Is BZG04-62TR3 compatible with lead-free reflow soldering processes?
Yes, the BZG04-62TR3 is lead (Pb)-free and RoHS-compliant per Directive 2002/95/EC, and its DO-214AC package is rated for standard Pb-free reflow profiles (JEDEC J-STD-020). The glass passivation ensures stability during peak temperatures up to 260 °C for 10 seconds.
What is the junction-to-lead thermal resistance (RthJL) of BZG04-62TR3?
The junction-to-lead thermal resistance RthJL for BZG04-62TR3 is 25 K/W, as specified in the Thermal Characteristics table of Vishay Document 85594. This value enables accurate thermal modeling when the device is soldered directly to a copper pour or thermal pad on the PCB.
