Product details
Overview
BZW06-10RL from STMicroelectronics is a unidirectional transient voltage suppression (TVS) diode in DO-15 package, designed to clamp ESD and surge transients up to 600 W (10/1000 µs) with a stand-off voltage of 10 V, clamping voltage of 17.1 V at 24 A, and junction temperature rating up to 175 °C. It protects power rails and I/O lines in industrial power supplies and telecom interfaces against IEC 61000-4-2 (±30 kV contact/air) and IEC 61000-4-4 (4 kV level 4) threats.
For engineers reviewing the BZW06-10RL datasheet, BZW06-10RL pinout, BZW06-10RL application, or BZW06-10RL equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, peak pulse current capability under 10/1000 µs waveform, thermal derating above 25 °C, and DO-15 mechanical compatibility with high-density PCB layouts.
Technical Context
The BZW06-10RL uses planar junction silicon technology to achieve low leakage (<0.2 µA at 10 V), stable breakdown behavior over -55 °C to +175 °C, and repeatable clamping performance across surge events. Its unidirectional configuration enables DC rail protection with cathode-anode polarity alignment to ground-referenced circuits.
It complies with IEC 61000-4-2 (±30 kV), IEC 61000-4-4 (4 kV), UL 497B, and JESD22-B102 E3 standards, and features dynamic resistance of 0.263 Ω at 24 A - enabling fast voltage limiting during sub-microsecond transients without excessive overshoot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 10 V - maximum continuous reverse operating voltage before significant leakage begins; sets upper limit for protected line voltage. |
| Breakdown Voltage (VBR) | 11.1–12.4 V at 1 mA - precise threshold where avalanche conduction initiates; ensures reliable triggering before downstream IC damage. |
| Clamping Voltage (VCL) | 17.1 V at 24 A (10/1000 µs) - maximum voltage seen by protected circuit during rated surge; must be below IC absolute max rating. |
| Peak Pulse Power (PPP) | 600 W (10/1000 µs) - energy-handling capacity for standard lightning/surge waveforms; derates to 300 W at Tj = 175 °C. |
| Leakage Current (IR) | ≤0.2 µA at 10 V - negligible standby power loss; critical for battery-powered or low-power sensor nodes. |
| Junction Temperature Range | -55 °C to +175 °C - supports operation in harsh environments including industrial motor drives and outdoor telecom enclosures. |
| Package | DO-15 (JEDEC DO-204AC) - axial-leaded through-hole package with 6.4 mm body length and 0.8 mm lead diameter; compatible with wave soldering and manual rework. |
Pinout & Package
DO-15 package: axial-leaded, glass-passivated planar junction diode with cathode band marking. Leads are matte tin-plated for solderability and RoHS compliance. Body length: 6.4 mm (typ), lead spacing: 28.5 mm (typ), lead diameter: 0.8 mm (typ).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Input/Line side for unidirectional protection | Connected to protected signal or power rail; conducts surge current toward cathode when reverse-biased beyond VBR. |
| Cathode (banded end) | Ground reference terminal | Connected to system ground or low-impedance return path; defines clamping reference and determines polarity of protection. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD robustness | ±30 kV air/contact discharge - eliminates need for external ESD filters on front-end ports in industrial HMIs and PLC modules. |
| High-temperature operation | Rated to 175 °C junction - enables placement near heat sources (e.g., MOSFETs, transformers) without derating penalties in SMPS designs. |
| Low dynamic resistance | 0.263 Ω at 24 A - minimizes clamping voltage overshoot during fast-rising surges, improving margin for 12 V logic and analog ICs. |
| UL 497B certification | Recognized for telecom/data line protection - satisfies safety agency requirements for secondary-circuit surge protection in PoE injectors and DSLAMs. |

IC Role / Device Role: Final-stage transient suppressor after isolation transformer and bridge rectifier. Use Value: Provides certified 4 kV IEC 61000-4-4 immunity while operating reliably at 85 °C ambient - meeting IEC 62053-21 thermal endurance requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | DO-214AA package; 600 W rating; VBR = 11.1–12.3 V; VCL = 17 V @ 24.5 A; higher capacitance (~100 pF) | SMT mounting only; unsuitable for through-hole legacy designs or high-vibration environments requiring axial leads | Select when board space is constrained and reflow assembly is available; verify layout clearance for SMB footprint. |
| P6KE10A | DO-15 package; 600 W rating; VBR = 10.5–11.6 V; VCL = 17.1 V @ 24.1 A; lower surge life cycle (1000 vs. >10,000 pulses) | Legacy part with older process; lacks UL 497B and IEC 61000-4-2 level 4 certification | Acceptable for cost-sensitive, non-certified consumer products; avoid in industrial or telecom deployments requiring full compliance. |
Compared with SMBJ10A and P6KE10A, BZW06-10RL offers superior high-temperature reliability (175 °C vs. 150 °C), lower leakage (<0.2 µA vs. 1 µA), and full IEC/UL certification - making it optimal for mission-critical industrial and telecom infrastructure where long-term stability and regulatory compliance are mandatory.

FAQ
What is the maximum surge current the BZW06-10RL can withstand?
The BZW06-10RL handles up to 24 A peak pulse current (10/1000 µs) at 25 °C, corresponding to its 600 W rating. At elevated junction temperatures (e.g., 125 °C), the surge current capability reduces to approximately 17 A due to thermal derating - verified per Figure 3 in DS0661 Rev 7.
How does the BZW06-10RL differ from bidirectional variants like BZW06-10BRL?
BZW06-10RL is unidirectional and protects DC lines referenced to ground, with anode-to-cathode polarity. BZW06-10BRL is bidirectional and used for AC or floating differential signals (e.g., RS-485), offering symmetrical clamping in both directions. Their VBR and VCL values differ slightly due to internal structure - BZW06-10BRL has VBR = 10.5–11.7 V and VCL = 17.5 V @ 23.5 A.
Can the BZW06-10RL be used in parallel for higher surge handling?
No - paralleling TVS diodes causes current imbalance due to VBR tolerance (±5 %), leading to premature failure of the lower-threshold device. For higher power, select a single higher-rated device (e.g., BZW06-15RL) or use staged protection with MOV + TVS, not parallel TVS units.
What is the recommended PCB layout for optimal thermal performance?
Use ≥1 cm² copper area per lead on FR4 board (per Figure 12), with thermal vias under pads if possible. Maintain ≥2 mm clearance from adjacent components to prevent arcing. Avoid sharp bends in leads; keep lead length <10 mm to minimize inductance that increases clamping voltage during fast transients.
