Product details
Overview
BZW06-5V8 from STMicroelectronics is a unidirectional transient voltage suppression (TVS) diode designed for primary-level ESD and surge protection in low-voltage DC power rails and signal lines. It features a 5.8 V stand-off voltage, 600 W peak pulse power (10/1000 µs), 10.5 A peak pulse current, and clamps transients to ≤13.4 V at 10 A. It is used in automotive body electronics, industrial sensor interfaces, and USB power input stages where low clamping voltage and high junction temperature operation up to 175 °C are required.
For engineers reviewing the BZW06-5V8 datasheet, BZW06-5V8 pinout, BZW06-5V8 application, or BZW06-5V8 equivalent, key selection criteria include its 5.8 V VRM rating, 10.5 A IPP capability, 13.4 V VCL at 10 A, DO-15 package thermal performance, and compliance with IEC 61000-4-2 (±30 kV contact/air) and IEC 61000-4-4 level 4 (4 kV).
Technical Context
The BZW06-5V8 employs planar junction technology optimized for low leakage (<20 µA at VRM) and stable clamping over temperature (αT = 5.7 × 10⁻⁴ /°C). Its dynamic resistance of 0.059 Ω enables tight voltage control during fast transients, supporting reliable protection in SMPS feedback loops and microcontroller I/O lines.
It operates across –55 °C to +175 °C junction temperature range and maintains 300 W surge capability at Tj = 175 °C. The device meets UL 497B (QVGQ2.E136224), IEC 61000-4-2 level 4, and IEC 61000-4-4 level 4 standards without derating at full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRM) | 5.8 V - Maximum continuous reverse operating voltage before conduction begins |
| Breakdown Voltage (VBR) | 6.45 V min @ 10 mA - Ensures reliable triggering before downstream IC damage thresholds |
| Clamping Voltage (VCL) | 13.4 V max @ 10.5 A - Limits transient voltage seen by protected circuitry under 10/1000 µs surge |

IC Role / Device Role: Unidirectional TVS on VCC line feeding isolated RS-485 transceiver (e.g., ADM2483), paired with bidirectional TVS on differential bus lines. Use Value: Prevents latch-up and permanent damage to transceiver power pins during 4 kV IEC 61000-4-4 bursts while maintaining <20 µA leakage at 5 V. |
| USB Type-A Port VBUS Protection | Smart Meter AC/DC Auxiliary Supply Input |
Use Scenario: Consumer-grade smart speaker with USB-A host port powering peripherals, exposed to hot-plug ESD and cable-borne noise. IC Role / Device Role: Standoff-rated TVS on VBUS line (5 V nominal), positioned between connector and USB switch or power delivery controller. Use Value: Limits VBUS overshoot to 13.4 V during ±15 kV ESD events, preserving USB enumeration integrity and preventing overvoltage shutdown. | Use Scenario: Utility smart meter with auxiliary 5 V supply derived from rectified AC mains, subject to surges and fast transients per IEC 61000-4-4. IC Role / Device Role: First-stage TVS on secondary-side 5 V rail after bridge rectifier and bulk capacitor, before linear regulator. Use Value: Absorbs 600 W surges without failure, enabling compliance with IEC 62053-21 immunity requirements for metering equipment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A | DO-214AA package; higher IRM (50 µA); VBR = 6.4 V min; VCL = 9.2 V @ 64.9 A | Higher IPP but larger footprint; better suited for PCB space-constrained designs requiring lower VCL | Select if board layout allows SMB package and lower clamping voltage is prioritized over axial lead serviceability |
| P6KE6.8A | DO-15 package; higher VBR (7.14 V min); VCL = 10.5 V @ 57 A; lower αT (4.5 × 10⁻⁴ /°C) | Less precise 5.8 V standoff; tighter tolerance not critical in non-precision 5 V rails | Choose for cost-sensitive industrial applications where 6.8 V VRM is acceptable and higher surge margin is needed |
Compared with SMBJ5.0A and P6KE6.8A, BZW06-5V8 offers the tightest VRM tolerance (5.8 V), lowest leakage (20 µA), and highest temperature stability (αT = 5.7 × 10⁻⁴ /°C), making it optimal for precision 5 V systems operating near thermal limits.

FAQ
What is the maximum clamping voltage of BZW06-5V8 at 10 A?
The maximum clamping voltage (VCL) is 13.4 V at 10.5 A for a 10/1000 µs waveform, measured at 25 °C. This value increases with junction temperature at a rate of 5.7 × 10⁻⁴ /°C, reaching ~14.2 V at Tj = 125 °C and ~14.7 V at Tj = 175 °C per the datasheet's temperature coefficient formula.
Can BZW06-5V8 be used in bidirectional signal line protection?
No - BZW06-5V8 is a unidirectional TVS diode, intended only for DC power rail or single-polarity signal protection. For bidirectional applications like RS-485 or Ethernet data lines, use the BZW06-5V8B variant, which has symmetrical breakdown in both directions and identical electrical ratings except for polarity behavior.
Does BZW06-5V8 meet automotive AEC-Q200 requirements?
BZW06-5V8 is not AEC-Q200 qualified. While it operates up to 175 °C and meets IEC/UL surge standards, ST does not list it in its AEC-Q200 stress-tested product portfolio. For automotive-critical applications, consider ST's AEC-Q200-qualified SMAJ5.0A or similar qualified variants.
What is the recommended PCB layout for optimal thermal performance?
For best thermal dissipation, use ≥1 cm² of 70 µm copper area under each lead (per Figure 12), avoid thermal relief on pads, and maintain ≥2 mm clearance from adjacent components. Mounting on FR4 with 2 oz copper improves Rth(j-a) from 4.5 °C/W (no copper) to ~2.1 °C/W, extending surge endurance at elevated ambient temperatures.
