Product details
Overview
BZG04-10TR from Vishay Semiconductors is a glass-passivated Zener diode optimized for transient voltage suppression in power and signal lines, with a nominal standoff voltage of 10 V, 3 W steady-state power dissipation at 100 °C ambient (RthJA < 25 K/W), 300 W non-repetitive peak surge power (10/1000 µs), and clamping voltage of 17.0 V at 20.3 A peak pulse current - deployed in industrial power supply input protection.
For engineers reviewing the BZG04-10TR datasheet, BZG04-10TR pinout, BZG04-10TR application, or BZG04-10TR equivalent, key selection criteria include verified 10 V Zener breakdown tolerance (±5 %), DO-214AC package thermal resistance (125 K/W on epoxy-glass hard tissue), and guaranteed 1 ps typical response time from 0 to VZmin under transient stress.
Technical Context
The BZG04-10TR operates as a unidirectional voltage-clamping device with precise Zener breakdown at 11.4 V minimum and 12.6 V maximum (at IZT = 50 mA), delivering stable regulation across temperature via low dynamic impedance and a temperature coefficient of +0.05 %/K. Its glass-passivated junction ensures long-term stability under repeated surge events.
Designed for high-energy transient suppression, it sustains 50 A peak forward surge current (10 ms half-sine) and exhibits 1000 pF junction capacitance at 0 V bias (1 MHz), enabling effective clamping without excessive signal distortion in DC-biased interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage | 10 V - defines maximum continuous reverse voltage before conduction begins; sets operating margin for 12 V rail protection. |
| Zener Breakdown Voltage | 11.4 V min / 12.6 V max @ 50 mA - tight tolerance enables predictable clamping onset in overvoltage fault conditions. |
| Clamping Voltage | 17.0 V @ 20.3 A (10/1000 µs) - actual voltage seen by protected circuit during surge; critical for downstream IC survivability. |
| Peak Surge Power | 300 W (10/1000 µs) - quantifies single-event energy-handling capability; exceeds IEC 61000-4-5 Level 4 requirements. |
| Junction Capacitance | 1000 pF @ 0 V, 1 MHz - impacts high-frequency noise coupling; suitable for DC/low-speed signal line protection, not RF paths. |
| Thermal Resistance | 125 K/W (epoxy-glass hard tissue, Fig. 1b) - determines safe power derating; requires PCB copper area for thermal management. |
| Response Time | ≤ 1 ps (0 to VZmin) - ensures sub-nanosecond reaction to fast transients such as ESD or lightning-induced spikes. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, molded plastic case with glass-passivated chip; weight ≈ 77 mg; standard 7" tape-and-reel (TR) packaging (1.5 k per reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased Zener terminal | Connected to protected node; conducts when transient exceeds VZ to shunt current to ground. |
| Anode | Reference/ground return path | Must be tied to low-impedance ground plane; loop inductance directly affects clamping performance. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable Zener voltage over 1000+ surge cycles and >150 °C junction operation without parameter drift. |
| High reliability rating | Qualified per AEC-Q200 stress tests; supports automotive body electronics and industrial control modules requiring >10-year field life. |
| Lead (Pb)-free & RoHS-compliant | Meets EU Directive 2002/95/EC and WEEE 2002/96/EC; compatible with lead-free reflow profiles (peak 260 °C). |
| Fast response time | ≤1 ps rise time ensures clamping activation before sensitive downstream components experience overstress. |
| Stand-off range support | Part of BZG04-Series covering 8.2 V–220 V; allows design reuse across multiple voltage rails using identical layout footprint. |
Applications
| Industrial Power Supply Input Protection | Automotive Body Control Module (BCM) CAN Bus Line Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Higher clamping voltage (17.0 V vs. 17.0 V same), but lower surge rating (600 W vs. 300 W), higher capacitance (1200 pF), DO-214AA package. | Preferred for higher-energy IEC 61000-4-5 Level 5 testing; less suitable where board space or capacitance budget is constrained. | Select SMBJ10A only if system-level surge test level exceeds 300 W or if DO-214AA footprint is already standardized. |
| 1N5349B | Through-hole DO-41 package; lower surge rating (150 W); wider VZ tolerance (±5 % same); slower response (>1 ns); no RoHS compliance noted. | Legacy repair or cost-sensitive non-RoHS designs; unsuitable for SMT production or high-reliability automotive use. | Choose 1N5349B only for manual assembly, prototyping, or legacy replacement where DO-214AC footprint and RoHS are not required. |
Compared with SMBJ10A and 1N5349B, the BZG04-10TR delivers optimal balance of compact DO-214AC footprint, certified RoHS compliance, sub-nanosecond response, and validated 300 W surge handling - making it preferred for new industrial and automotive SMT designs requiring repeatability and thermal efficiency.

FAQ
What is the Zener breakdown voltage tolerance for BZG04-10TR?
The BZG04-10TR has a Zener breakdown voltage range of 11.4 V minimum to 12.6 V maximum at test current IZT = 50 mA, corresponding to ±5 % tolerance around the nominal 12 V breakdown point. This tolerance is confirmed in the Electrical Characteristics table of Vishay Document Number 85594 Rev. 2.2. The BZG04-10TR maintains this specification across its qualified operating temperature range.
Is BZG04-10TR suitable for bidirectional transient suppression?
No, the BZG04-10TR is a unidirectional Zener diode and provides clamping only for positive transients on the cathode relative to anode. It does not protect against reverse-polarity events. For bidirectional protection, a TVS array or back-to-back Zener configuration is required. The BZG04-10TR datasheet explicitly defines its operation as unidirectional clamping.
What is the maximum junction temperature rating for BZG04-10TR?
The BZG04-10TR has a maximum junction temperature (Tj) rating of 150 °C, as specified in the Absolute Maximum Ratings table. Operation beyond this limit risks permanent degradation of the glass-passivated junction. Derating curves in Figure 5 of the datasheet must be applied when ambient temperature exceeds 25 °C or power dissipation exceeds 1.25 W.
Does BZG04-10TR meet RoHS and lead-free soldering requirements?
Yes, the BZG04-10TR is lead (Pb)-free and compliant with RoHS Directive 2002/95/EC and WEEE 2002/96/EC. It is qualified for lead-free reflow soldering with peak temperatures up to 260 °C, as stated in the Features section of Vishay Document Number 85594 Rev. 2.2. The BZG04-10TR carries the "e3" marking indicating matte tin termination.
How does the thermal resistance of BZG04-10TR vary with PCB layout?
The BZG04-10TR's junction-to-ambient thermal resistance (RthJA) depends on mounting: 150 K/W on minimal copper, 125 K/W on epoxy-glass hard tissue (Fig. 1b), and 100 K/W on Al₂O₃ ceramic substrate. Layout changes - especially copper pad area and via count under the cathode/anode pads - directly impact steady-state power handling. The BZG04-10TR datasheet specifies these values in the Thermal Characteristics table.
