Product details
Overview
BZW06-5V8RL from STMicroelectronics is a unidirectional transient voltage suppression (TVS) diode in DO-15 package, designed for primary-level ESD and surge protection of low-voltage DC lines. It features a 5.8 V standoff voltage (VRM), 10.5 V clamping voltage at 10 A (VCL), 600 W peak pulse power (10/1000 µs), and operates up to 175 °C junction temperature - deployed in power supply inputs, USB ports, and industrial sensor interfaces.
For engineers reviewing the BZW06-5V8RL datasheet, BZW06-5V8RL pinout, BZW06-5V8RL application, or BZW06-5V8RL equivalent, key selection criteria include clamping performance at 10 A, leakage current ≤20 nA at VRM, thermal stability up to 175 °C, and compatibility with JEDEC DO-204AC board layout standards.
Technical Context
This planar-junction TVS diode uses silicon avalanche technology to clamp transient overvoltages before they damage downstream ICs. Its unidirectional polarity enables asymmetric protection on positive-rail lines, with low dynamic resistance (0.059 Ω) ensuring minimal voltage overshoot during 10/1000 µs surges.
It meets IEC 61000-4-2 level 4 (30 kV air/contact discharge) and IEC 61000-4-4 level 4 (4 kV), and supports high-reliability operation in SMPS and automotive body electronics where low leakage (<20 nA at 5.8 V) and stable VBR (6.45–6.8 V) across temperature are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRM) | 5.8 V - maximum continuous reverse operating voltage before breakdown |
| Breakdown Voltage (VBR) | 6.45–6.8 V at 10 mA - defines precise conduction onset for predictable clamping |
| Clamping Voltage (VCL) | 10.5 V at 10 A (10/1000 µs) - limits voltage seen by protected circuit during surge |
| Peak Pulse Power | 600 W (10/1000 µs) - sustains industrial-grade surge events without failure |
| Leakage Current (IRM) | ≤20 nA at 5.8 V - ensures negligible standby power loss in battery-powered systems |
| Junction Temperature Range | −55 °C to +175 °C - supports under-hood and industrial ambient environments |
| Dynamic Resistance (RD) | 0.059 Ω - minimizes voltage rise under high-current transients |
Pinout & Package
DO-15 (JEDEC DO-204AC) axial-leaded package with cathode band marking; lead finish: matte tin plating; RoHS-compliant ECOPACK2 grade.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry / surge return path | Connected to ground or low-side reference in unidirectional configuration |
| Cathode (banded end) | Protected line connection | Placed directly on signal/power line to be safeguarded; clamps to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Rated for continuous use up to 175 °C junction temperature - eliminates derating in compact enclosures |
| Low clamping ratio | VCL/VBR = 10.5/6.45 ≈ 1.63 - tighter voltage control than standard Zener-based protectors |
| ESD robustness | Withstands 30 kV contact/air discharge per IEC 61000-4-2 level 4 - exceeds consumer and industrial immunity requirements |
| Planar junction construction | Enables low leakage (<20 nA) and stable VBR drift (αT = 5.7 × 10⁻⁴/°C) - critical for precision analog front-ends |
Applications
| Industrial Power Input Protection | USB 2.0 Data Line Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A | Higher clamping voltage (11.2 V at 10 A); SMB package (surface-mount) | Requires PCB rework for SMT layout; less suitable for through-hole legacy designs | Select when board space is constrained and automated assembly is used |
| P6KE6.8A | Lower peak power (600 W same, but derates faster above 25 °C); DO-15, same footprint | Limited to ≤150 °C operation; higher leakage (50 µA vs. 20 nA) | Select only for cost-sensitive non-automotive applications with ambient <85 °C |
Compared with SMBJ5.0A and P6KE6.8A, BZW06-5V8RL delivers superior thermal margin (175 °C), lower leakage (20 nA), and tighter VBR tolerance (±5%), making it optimal for high-reliability 5 V rail protection where long-term stability matters.

FAQ
What is the maximum clamping voltage of BZW06-5V8RL at 10 A?
The maximum clamping voltage (VCL) is 10.5 V under 10/1000 µs waveform conditions at 10 A peak current and 25 °C ambient. This value increases predictably with junction temperature using αT = 5.7 × 10⁻⁴/°C, reaching ~11.2 V at 125 °C junction.
Is BZW06-5V8RL unidirectional or bidirectional?
BZW06-5V8RL is unidirectional, indicated by the absence of "B" suffix (e.g., BZW06-5V8B is bidirectional). Its cathode band marks the protected line terminal; anode connects to ground or reference, enabling asymmetric surge shunting on positive rails only.
Does BZW06-5V8RL meet automotive qualification standards?
While not AEC-Q200 qualified, BZW06-5V8RL meets IEC 61000-4-2/4-4 level 4 and operates up to 175 °C junction temperature - widely deployed in automotive body electronics (e.g., BCMs, mirror controls) where full AEC-Q200 is not mandated but thermal and ESD robustness are essential.
What is the typical junction capacitance at 1 V reverse bias?
Typical junction capacitance is approximately 1000 pF at 1 V reverse bias and 1 MHz, measured on unidirectional variants like BZW06-5V8. This value decreases rapidly with increasing reverse voltage - down to ~100 pF at 5 V - supporting effective high-speed transient suppression without signal distortion.
