Product details
Overview
BZG04-10TR3 from Vishay Semiconductors is a glass-passivated Zener diode optimized for transient voltage suppression in power supply and signal line protection circuits, with a nominal Zener voltage of 10 V, 3 W steady-state power dissipation at 100 °C ambient, 300 W non-repetitive surge power rating (10/1000 µs), and clamping voltage of 17.0 V at 20.3 A peak pulse current - deployed in industrial DC power rails and automotive body control modules.
For engineers reviewing the BZG04-10TR3 datasheet, BZG04-10TR3 pinout, BZG04-10TR3 application, or BZG04-10TR3 equivalent, key selection criteria include verified clamping performance under 10/1000 µs transients, thermal resistance to ambient (125 K/W on epoxy-glass hard tissue), DO-214AC package compatibility with automated SMT placement, and RoHS-compliant lead-free construction.
Technical Context
The BZG04-10TR3 operates as a unidirectional voltage-clamping device with a precisely defined Zener breakdown voltage (11.4 V min, 12.6 V max at 5 mA test current) and fast response time (≤1 ps). Its glass-passivated junction ensures stable leakage current (<5 µA at 8.2 V standoff) and high reliability under repeated surge stress.
Thermal design relies on its low junction-to-lead thermal resistance (25 K/W) and configurable junction-to-ambient resistance (100–150 K/W depending on PCB mounting), enabling robust operation up to 150 °C junction temperature while maintaining clamping integrity during 10 ms half-sine forward surge events (50 A rating).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11.4 V min / 12.6 V max @ IZT = 5 mA - defines precise clamping threshold for overvoltage protection |
| Clamping Voltage (VCL) | 17.0 V typ @ IPP = 20.3 A (10/1000 µs) - actual voltage seen by protected circuit during surge |
| Steady-State Power (Pdiss) | 3 W @ Tamb = 100 °C with RthJA < 25 K/W - determines continuous thermal derating capability |
| Surge Power (PZSM) | 300 W @ tp = 10/1000 µs - enables handling of high-energy lightning-induced transients |
| Junction Temperature (Tj) | 150 °C max - sets upper thermal limit for safe operation in enclosed or high-ambient environments |
| Package | DO-214AC (SMA) - industry-standard surface-mount outline with 77 mg mass and validated reflow profile |

Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| SMBJ10A | Higher clamping voltage (17.0 V vs. 16.7 V), same DO-214AA package, 600 W surge rating | Designed for bidirectional AC-line protection; requires polarity-aware layout for DC use | Select when higher surge margin is required and board space allows SMB footprint |
| P6SMB10A | Same 10 V nominal Zener, 600 W PZSM, but larger DO-214AA package (higher RthJA ≈ 160 K/W) | Lower thermal efficiency in dense layouts; less suitable for high-power-density designs | Prefer for cost-sensitive applications where thermal derating is not critical |
Compared with SMBJ10A and P6SMB10A, the BZG04-10TR3 offers tighter Zener tolerance (±5.7% vs. ±10%), lower RthJA (125 K/W vs. ≥160 K/W), and smaller DO-214AC footprint - making it optimal for thermally constrained, high-precision DC rail protection.

FAQ
What is the Zener voltage tolerance of BZG04-10TR3?
The BZG04-10TR3 has a Zener voltage range of 11.4 V minimum to 12.6 V maximum at 5 mA test current, corresponding to a ±5.7% tolerance around the nominal 10 V designation. This tight tolerance ensures predictable clamping behavior in precision protection circuits where overvoltage margin is critical. The BZG04-10TR3 achieves this via process-controlled doping and glass passivation, verified per Document Number 85594 Rev. 2.2.
Can BZG04-10TR3 be used in bidirectional surge protection?
No - the BZG04-10TR3 is a unidirectional Zener diode intended for DC line protection with defined anode/cathode polarity. It does not provide symmetrical clamping for AC or reversible transients. For bidirectional applications, a pair of BZG04-10TR3 devices in series opposition or a dedicated bidirectional TVS like SMBJ10CA would be required. The BZG04-10TR3 datasheet specifies only forward and reverse breakdown characteristics, not symmetrical surge response.
What is the maximum allowable junction temperature for BZG04-10TR3?
The absolute maximum junction temperature for BZG04-10TR3 is 150 °C, as specified in the Absolute Maximum Ratings table. Operation above this temperature risks irreversible degradation of the glass-passivated junction and accelerated Zener voltage drift. Derating curves in Figure 5 of Document 85594 show thermal resistance dependence on pulse duration, confirming that sustained operation must remain within this limit. The BZG04-10TR3 must be mounted per Figure 1b guidelines to maintain safe thermal margins.
How does the clamping voltage of BZG04-10TR3 compare to its Zener voltage?
The clamping voltage of BZG04-10TR3 is 17.0 V typical at 20.3 A peak pulse current (10/1000 µs waveform), which is ~50% higher than its nominal Zener voltage of 10 V. This difference reflects dynamic impedance rise under high-current surge conditions and is essential for sizing downstream protection margins. The BZG04-10TR3 datasheet explicitly lists VCL(R) = 17.0 V, confirming its real-world clamping performance exceeds static Zener ratings - a key parameter for validating system-level surge immunity.
Is BZG04-10TR3 compatible with lead-free reflow soldering processes?
Yes - the BZG04-10TR3 is lead-free and RoHS-compliant per Directive 2002/95/EC, with termination finish qualified for standard Pb-free reflow profiles (peak temperature ≤260 °C, 60-second exposure). Its glass-passivated junction remains stable through JEDEC J-STD-020-compliant thermal cycling. The BZG04-10TR3 packaging code "TR3" denotes 6 k unit reels compatible with high-speed SMT placement equipment, and Vishay confirms full compatibility with IPC-A-610 Class 2 and Class 3 assembly requirements.
