Product details
Overview
BZW06-15RL from STMicroelectronics is a unidirectional transient voltage suppression (TVS) diode in DO-15 package, designed for primary-level ESD and surge protection in DC power rails and signal lines. It features a 15 V stand-off voltage (VRM), 25.2 A peak pulse current (IPP) at 10/1000 µs, 24.0 V clamping voltage (VCL), <0.2 µA reverse leakage at 15 V, and operates up to +175 °C junction temperature - deployed in industrial power supplies and automotive body control modules.
For engineers reviewing the BZW06-15RL datasheet, BZW06-15RL pinout, BZW06-15RL application, or BZW06-15RL equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD tolerance, IPP derating at elevated Tj, bidirectional vs. unidirectional polarity requirements, and DO-15 thermal pad layout compatibility with FR4 PCB copper area.
Technical Context
The BZW06-15RL uses planar junction silicon technology to achieve low dynamic resistance (RD = 0.263 Ω) and stable VBR (17.1–18.9 V) across -55 °C to +175 °C. Its IEC 61000-4-2 compliance (30 kV air/contact discharge) and IEC 61000-4-4 level 4 rating (4 kV) confirm suitability for harsh EMC environments.
It delivers 600 W peak pulse power at 25 °C (10/1000 µs), derating to 300 W at Tj = 175 °C. The device exhibits negligible capacitance (<100 pF at 1 V) and ultra-low leakage (<0.2 µA at VRM), enabling use on high-speed analog or low-power microcontroller I/O lines without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRM) | 15 V - maximum continuous reverse working voltage before conduction begins |
| Breakdown Voltage (VBR) | 17.1–18.9 V at 1 mA - ensures reliable triggering above system rail while avoiding false trips |
| Clamping Voltage (VCL) | 24.0 V at 25.2 A (10/1000 µs) - limits transient voltage seen by downstream ICs to safe levels |
| Peak Pulse Power (PPP) | 600 W (10/1000 µs, 25 °C) - supports common surge immunity test profiles per IEC 61000-4-4 |
| Leakage Current (IRM) | <0.2 µA at 15 V - prevents excessive quiescent current in battery-powered or low-power systems |
| Junction Temperature Range | -55 °C to +175 °C - enables deployment in under-hood automotive or industrial motor drive environments |
| Dynamic Resistance (RD) | 0.263 Ω - determines VCL rise slope under surge (ΔV = RD × ΔI), critical for fast-rising transients |
Pinout & Package
DO-15 (JEDEC DO-204AC) axial-leaded package with cathode band marking; lead finish: matte tin plating; MSL Level 1; RoHS-compliant ECOPACK2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry during forward conduction | Connected to ground or low-side return path in unidirectional configuration |
| Cathode (banded end) | Current exit during reverse-biased clamping | Connected to protected line (e.g., 12 V rail); clamps to anode when overvoltage occurs |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Rated for continuous operation up to +175 °C junction temperature - eliminates derating concerns in sealed enclosures |
| Low clamping ratio | VCL/VBR ≈ 1.41 - provides tight voltage limiting with minimal headroom overhead vs. protected IC absolute max ratings |
| ESD robustness | 30 kV contact/air discharge per IEC 61000-4-2 - exceeds Level 4, suitable for handheld and exposed interfaces |
| Low dynamic resistance | 0.263 Ω - minimizes clamping voltage overshoot during fast 8/20 µs surges (e.g., lightning-induced) |
| Planar junction construction | Enables stable leakage and VBR over lifetime - critical for long-life industrial equipment requiring >10-year reliability |
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 transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | DO-214AA package; 600 W PPP; VBR = 16.7–18.5 V; VCL = 24.4 V at 24.5 A | Surface-mount footprint; higher thermal resistance than DO-15 on same PCB copper area | Preferred for automated SMT assembly where board space is constrained and reflow profile allows |
| P6KE15A | DO-15 package; 600 W PPP; VBR = 15.2–16.8 V; VCL = 24.4 V at 24.5 A; higher IRM (1.0 µA) | Legacy design; wider VBR tolerance; less stable leakage at high Tj | Acceptable for cost-sensitive, non-automotive applications where 175 °C operation is not required |
Compared with SMBJ15A and P6KE15A, BZW06-15RL offers superior high-temperature stability (175 °C Tj max), lower leakage (<0.2 µA), and tighter VBR distribution - making it optimal for thermally demanding industrial and automotive deployments where long-term reliability is critical.

FAQ
What is the maximum allowable soldering temperature and duration for BZW06-15RL?
The device supports a peak reflow temperature of 240–245 °C for 20–40 seconds, per ST's recommended JEDEC J-STD-020 profile. Lead temperature must not exceed 260 °C for more than 10 seconds during hand soldering. Exceeding these limits risks internal bond wire damage and increased leakage.
Can BZW06-15RL be used in bidirectional protection configurations?
No - BZW06-15RL is unidirectional only, with cathode band marking. For bidirectional protection, use the BZW06-15B variant, which has symmetrical breakdown in both polarities and dual-band marking. Substituting the unidirectional version in AC-coupled or floating-line applications may result in forward conduction and failure.
How does clamping voltage change at elevated junction temperatures?
VCL increases linearly with junction temperature using the tempco αT = 8.9 × 10⁻⁴ /°C. At 125 °C, VCL rises ~0.9 V above its 25 °C value (24.0 V → ~24.9 V at 25.2 A). This must be factored into margin analysis against protected IC absolute maximum ratings.
Is BZW06-15RL compliant with UL 497B for telecom surge protection?
Yes - it carries UL 497B file number QVGQ2.E136224, certifying suitability for secondary circuit protection in telecommunications equipment. It meets all associated dielectric withstand, flammability (UL94 V0), and surge endurance requirements defined in that standard.
