Product details
Overview
BZW06-10BRL from STMicroelectronics is a bidirectional transient voltage suppression (TVS) diode in DO-15 package, designed for IEC 61000-4-2 ESD protection (30 kV air/contact discharge) and IEC 61000-4-4 surge immunity (4 kV level 4). It features a standoff voltage of 10 V, clamping voltage of 17.1 V at 24 A (8/20 µs), and peak pulse power rating of 600 W (10/1000 µs) at 25 °C - used to safeguard USB ports, industrial sensor interfaces, and AC/DC front-end inputs.
For engineers reviewing the BZW06-10BRL datasheet, BZW06-10BRL pinout, BZW06-10BRL application, or BZW06-10BRL equivalent, key selection criteria include verified clamping performance at 175 °C junction temperature, low dynamic resistance (0.263 Ω), compliance with UL 497B and IEC 61000-4-2/4-4, and DO-15 mechanical compatibility with high-density PCB layouts.
Technical Context
This bidirectional TVS diode employs planar silicon junction technology optimized for low leakage (<0.2 µA at VRM = 10 V) and stable clamping over -55 °C to +175 °C operating junction range. Its symmetrical breakdown behavior enables robust protection against both positive and negative transients without polarity dependency.
The device delivers 600 W peak pulse power under 10/1000 µs waveform at ambient temperature and sustains up to 300 W at Tj = 175 °C. Dynamic resistance (RD = 0.263 Ω) and temperature coefficient αT = 8.9 × 10⁻⁴ /°C ensure predictable VCL drift across thermal conditions, critical for precision input-stage protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRM) | 10 V - maximum continuous reverse working voltage before conduction begins |
| Breakdown Voltage (VBR) | 11.1–12.4 V at 1 mA - guaranteed avalanche onset threshold for bidirectional clamping |
| Clamping Voltage (VCL) | 17.1 V at 24 A (8/20 µs) - peak voltage seen by protected circuit during worst-case surge |
| Peak Pulse Power (PPP) | 600 W (10/1000 µs) - energy-handling capacity for standard lightning-surge waveforms |
| Leakage Current (IRM) | 0.2 µA max at 10 V - negligible DC loading on signal lines or supply rails |
| Junction Temperature Range | -55 °C to +175 °C - supports operation in automotive engine bays and industrial power supplies |
| ESD Rating | 30 kV contact & air discharge per IEC 61000-4-2 - exceeds level 4 for human-body-model robustness |
Pinout & Package
DO-15 (JEDEC DO-204AC) axial-leaded package with matte tin-plated leads; cathode band marked on body. Compatible with wave and reflow soldering per J-STD-020 MSL level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Transient current entry (negative half-cycle) | Conducts during negative surges; symmetrically identical to cathode in bidirectional configuration |
| Cathode (Lead 2) | Transient current entry (positive half-cycle) | Conducts during positive surges; no polarity distinction - interchangeable in layout |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature surge capability | 300 W peak pulse power at Tj = 175 °C - maintains protection integrity in thermally stressed environments |
| Low dynamic resistance | 0.263 Ω - minimizes clamping voltage overshoot during fast-rising transients (e.g., EFT bursts) |
| UL 497B certification | QVGQ2.E136224 file number - validated for telecom/data line surge protection per safety standards |
| Planar junction construction | Enables <0.2 µA leakage at 10 V - preserves signal integrity in high-impedance analog/sensor circuits |
Applications
| Industrial Sensor Interface | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting 4–20 mA current-loop transmitters and RS-485 nodes from induced surges in factory-floor wiring. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across differential pair or supply-to-ground. Use Value: Limits transient voltage to ≤17.1 V during 24 A 8/20 µs surge, preventing damage to isolated ADCs or digital isolators. |
Use Scenario: Safeguarding D+ and D− lines of embedded USB host controllers against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Low-capacitance (≈100 pF) TVS placed directly at connector pins. Use Value: Withstands 30 kV contact discharge while adding <1 ns propagation delay - no USB 2.0 timing violation. |
| AC/DC Power Supply Input | Smart Meter Communication Port |
Use Scenario: Front-end protection of offline SMPS rectifier outputs against line-switching transients and lightning-induced surges. IC Role / Device Role / Timing Role: Parallel-connected TVS across bulk capacitor or bridge rectifier output. Use Value: Absorbs 600 W (10/1000 µs) without thermal runaway, enabling compact design vs. MOV-based solutions. |
Use Scenario: Securing PLC or RF module interfaces in utility-grade smart meters exposed to field ESD and conducted noise. IC Role / Device Role / Timing Role: Bidirectional clamp on HART or M-Bus signal lines referenced to system ground. Use Value: Complies with IEC 61000-4-4 level 4 (4 kV) and maintains <0.2 µA leakage - avoids meter calibration drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | DO-214AA package; 600 W rating; VBR = 11.1–12.3 V; VCL = 17.0 V @ 34.4 A (8/20 µs) | Higher IPP (34.4 A vs. 24 A) but larger footprint - better for higher-energy surges where board space allows | Select when surge current >24 A is expected and DO-214AA mounting is acceptable |
| P6KE10CA | DO-15 package; 600 W rating; VBR = 8.5–9.4 V; VCL = 14.5 V @ 41.4 A (8/20 µs); lower VRM | Lower standoff voltage limits use in 12 V systems only; tighter VCL improves protection margin but reduces operating headroom | Prefer for 12 V nominal rails where lower clamping voltage outweighs reduced VRM margin |
Compared with SMBJ10CA and P6KE10CA, BZW06-10BRL offers optimal balance of DO-15 form factor, 10 V VRM headroom for 12 V systems, and verified 175 °C operation - making it preferred for space-constrained industrial power and interface designs requiring extended thermal reliability.

FAQ
What is the maximum junction temperature for continuous operation?
BZW06-10BRL supports continuous operation from -55 °C to +175 °C junction temperature. Its planar junction structure and thermal impedance profile enable sustained 300 W surge handling even at Tj = 175 °C, as confirmed in Figure 3 of DS0661 Rev 7.
Does BZW06-10BRL meet IEC 61000-4-5 requirements?
No - BZW06-10BRL is rated for IEC 61000-4-4 (EFT) and IEC 61000-4-2 (ESD) only. It is not specified for IEC 61000-4-5 (lightning surge) due to its 600 W 10/1000 µs rating, which falls below typical 4–10 kV line-to-ground test levels requiring ≥1 kW devices.
Is the DO-15 package RoHS and REACH compliant?
Yes - BZW06-10BRL carries ST's ECOPACK2 designation, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Lead finish is matte tin plating, and the device is rated J-STD-020 MSL level 1 with unlimited floor life at ≤30 °C/60% RH.
How does bidirectional operation affect PCB layout?
Bidirectional symmetry means anode and cathode leads are functionally identical - no polarity marking is required during placement. Layout requires equal trace length and impedance to both terminals to preserve balanced clamping; no ground reference is needed beyond standard PCB return paths.
