Product details
Overview
BZW06-15BRL from STMicroelectronics is a unidirectional transient voltage suppression (TVS) diode in DO-15 package, designed for IEC 61000-4-2 ESD and IEC 61000-4-4 surge protection. It features a standoff voltage (VRM) of 15 V, clamping voltage (VCL) of 25.2 V at 24 A peak pulse current (IPP), and 600 W peak pulse power (10/1000 µs) at 25 °C. Used in DC power rails and low-speed signal lines of industrial power supplies and telecom interfaces.
For engineers reviewing the BZW06-15BRL datasheet, BZW06-15BRL pinout, BZW06-15BRL application, or BZW06-15BRL equivalent, key selection criteria include its 15 V reverse standoff, 25.2 V clamping at 24 A, DO-15 mechanical compatibility, 0.2 µA max leakage at VRM, and 175 °C junction temperature rating - all critical for robust overvoltage protection in high-reliability embedded systems.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below 15 V (VRM), then avalanches sharply above 17.1 V (VBR min) to divert transients. Its planar junction enables low leakage (≤0.2 µA) and stable performance up to 175 °C junction temperature.
The device meets IEC 61000-4-2 level 4 (30 kV air/contact discharge) and IEC 61000-4-4 level 4 (4 kV), with dynamic resistance (RD) of 0.263 Ω enabling precise clamping control under fast-rising surges. Thermal impedance is optimized for FR4 PCBs with standard copper land patterns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRM) | 15 V - maximum continuous reverse operating voltage before conduction begins |
| Breakdown Voltage (VBR) | 17.1–18.9 V at 1 mA - guaranteed avalanche initiation range for reliable triggering |
| Clamping Voltage (VCL) | 25.2 V at 24 A (10/1000 µs) - maximum voltage seen by protected circuit during rated surge |
| Peak Pulse Power (PPP) | 600 W (10/1000 µs, 25 °C) - surge energy handling capacity for common lightning-induced transients |
| Leakage Current (IRM) | 0.2 µA max at VRM - negligible standby power loss and minimal signal distortion in high-impedance circuits |
| Junction Temperature (Tj) | −55 to +175 °C - supports operation in harsh environments including industrial motor drives and outdoor telecom equipment |
| Dynamic Resistance (RD) | 0.263 Ω - ensures tight clamping tolerance and predictable voltage overshoot under varying surge currents |
Pinout & Package
DO-15 (JEDEC DO-204AC) axial-leaded package with cathode band marking. Standard lead finish: matte tin plating. Compatible with wave and reflow soldering per J-STD-020 MSL level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry during forward conduction | Connected to ground or lower-potential rail in unidirectional protection configuration |
| Cathode (banded end) | Current exit during reverse avalanche | Connected to protected line (e.g., 15 V supply rail); defines polarity-sensitive clamping direction |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD immunity | 30 kV contact & air discharge - exceeds level 4, eliminating need for external ESD staging in many front-end designs |
| Low dynamic resistance | 0.263 Ω - minimizes clamping voltage rise under high di/dt surges, improving system-level surge margin |
| High-temperature reliability | Rated to 175 °C Tj - maintains clamping performance in thermally constrained enclosures without derating |
| Planar junction technology | Enables <0.2 µA IR at VRM - preserves signal integrity in high-impedance sensor or reference circuits |
| UL 497B certified | QVGQ2.E136224 - validated for telecom and industrial interface protection per safety-critical standards |
Applications
| Industrial Power Supply Input Protection | Telecom Line Interface Protection |
|---|---|
Use Scenario: 24 V DC input stage of programmable logic controller (PLC) power module exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between input rail and chassis ground to clamp surges before they reach upstream regulators. Use Value: Clamps 600 W transients to ≤25.2 V, preventing damage to 36 V-rated input capacitors and enabling compliance with IEC 61000-4-4 level 4. | Use Scenario: RS-485 data line termination in outdoor base station equipment subject to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Paired unidirectional TVS devices (one per line) referenced to local ground, providing differential and common-mode surge suppression. Use Value: Limits transient voltage to 25.2 V during 24 A pulses, protecting transceivers with ±15 V common-mode range while maintaining <1 ns response time. |
| Automotive Body Control Module (BCM) Sensor Inputs | Medical Equipment AC/DC Adapter Input |
Use Scenario: 12 V supply rail feeding Hall-effect position sensors in engine bay modules where thermal cycling and ESD are frequent. IC Role / Device Role / Timing Role: Primary overvoltage clamp on sensor VDD line, coordinated with upstream fuse and downstream LDO. Use Value: Withstands 175 °C ambient and delivers <0.2 µA leakage at 15 V, ensuring sensor bias stability and avoiding false fault triggers. | Use Scenario: Secondary-side DC output (15 V) of medical-grade AC/DC adapter used in patient-monitoring devices requiring reinforced isolation and low EMI. IC Role / Device Role / Timing Role: Final-stage transient suppressor on regulated output, guarding against capacitor discharge events and coupling from internal switching noise. Use Value: UL 497B certification validates safety compliance; 25.2 V clamping prevents latch-up in downstream analog front-end ICs with 24 V absolute max ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | Same DO-214AC package; 600 W rating; slightly higher VBR (16.7–18.5 V) and VCL (24.4 V @ 24.4 A) | Lower thermal mass than DO-15; less suitable for high-temperature ambient (>125 °C) without board-level heatsinking | Select when SMT assembly is required and board space is constrained; verify thermal relief pad design for 175 °C operation |
| P6KE15A | DO-15 package; 600 W rating; higher VCL (25.8 V @ 23.3 A); larger junction capacitance (1500 pF @ 0 V) | Higher leakage (5 µA) and lower ESD rating (16 kV) limit use in low-power sensor nodes and precision analog paths | Prefer for cost-sensitive industrial controls where ESD immunity >20 kV is not mandated and layout allows larger capacitance |
Compared with SMAJ15A and P6KE15A, BZW06-15BRL offers the lowest leakage (0.2 µA), highest ESD rating (30 kV), and best thermal capability (175 °C Tj) in the DO-15 form factor - making it optimal for high-reliability, high-temperature, and low-noise applications where long-term stability is critical.

FAQ
What is the maximum clamping voltage of BZW06-15BRL under a 10/1000 µs surge?
The maximum clamping voltage (VCL) is 25.2 V at 24 A peak pulse current for a 10/1000 µs waveform, measured at 25 °C ambient. This value increases with junction temperature at a coefficient of 8.9 × 10⁻⁴ V/°C, reaching ~27.1 V at 175 °C Tj.
Is BZW06-15BRL suitable for bidirectional signal line protection?
No - BZW06-15BRL is unidirectional and must be used with correct polarity (cathode to protected line). For bidirectional protection, use the BZW06-15B variant, which has symmetrical breakdown in both directions and identical marking except for the 'B' suffix.
How does the DO-15 package affect thermal performance compared to SMD alternatives?
The DO-15 axial package provides superior thermal dissipation into PCB copper planes via both leads, achieving lower Rth(j-a) than most SMD packages under identical board layouts. At 1 cm² copper per lead, Rth(j-a) is ~4.5 °C/W - enabling full 600 W surge handling even at 175 °C ambient when properly mounted.
Does BZW06-15BRL require derating for operation above 25 °C ambient?
Yes - peak pulse power must be linearly derated above 25 °C. At 100 °C ambient, PPP drops to ~420 W; at 150 °C, it falls to ~270 W. Derating follows the curve in Figure 3 of DS0661 Rev 7 and is defined by junction temperature, not ambient alone - board thermal design directly impacts usable power.
