Product details
Overview
BZW06-13RL from STMicroelectronics is a unidirectional transient voltage suppression 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 13 V, clamping voltage of 21.2 V at 28.6 A, and junction temperature rating up to 175 °C. It protects power rails and I/O lines in industrial power supplies and telecom interfaces.
For engineers reviewing the BZW06-13RL datasheet, BZW06-13RL pinout, BZW06-13RL application, or BZW06-13RL equivalent, key selection criteria include clamping voltage vs. peak pulse current, leakage current at 13 V (<0.2 µA), thermal derating above 25 °C, and DO-15 mechanical compatibility with high-density PCB layouts.
Technical Context
The BZW06-13RL uses planar junction technology to achieve low dynamic resistance (0.427 Ω) and stable clamping performance across temperature. Its unidirectional configuration enables asymmetric protection on DC-biased lines, with reverse standoff voltage (VRM) of 13 V and breakdown voltage (VBR) min. 14.4 V at 1 mA.
It meets IEC 61000-4-2 level 4 (±30 kV air/contact discharge) and IEC 61000-4-4 level 4 (4 kV), with thermal impedance (Zth(j-a)) of ~100 °C/W for single-pulse conditions on FR4 PCBs - enabling reliable operation in thermally constrained industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRM) | 13 V - maximum continuous reverse operating voltage before conduction begins |
| Breakdown Voltage (VBR) | 14.4–16.0 V at 1 mA - precise threshold where avalanche conduction initiates |
| Clamping Voltage (VCL) | 21.2 V at 28.6 A (10/1000 µs) - peak voltage seen by protected circuit during surge |
| Peak Pulse Power (PPP) | 600 W (10/1000 µs) - maximum transient energy dissipation capability at 25 °C |
| Leakage Current (IRM) | <0.2 µA at 13 V - negligible standby power loss in always-on systems |
| Junction Temperature Range | −55 to +175 °C - supports operation in harsh environments including motor drives and outdoor telecom |
| Dynamic Resistance (RD) | 0.427 Ω - determines voltage rise under increasing surge current (ΔV = RD × ΔI) |
Pinout & Package
DO-15 (JEDEC DO-204AC) axial-leaded package with cathode band marking; leads are matte tin-plated for solderability and RoHS compliance. Dimensions: A = 6.05–6.75 mm (body length), B = 26–31 mm (lead length), C = 2.95–3.53 mm (body diameter), D = 0.71–0.88 mm (lead diameter).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to ground or low-impedance return in unidirectional TVS configuration |
| Cathode | Protected line connection | Connected to line being protected (e.g., 12 V rail); marked with band |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Rated for continuous use up to 175 °C junction temperature - eliminates derating concerns in enclosed power modules |
| Low clamping ratio | VCL/VBR ≈ 1.43 - ensures minimal overvoltage stress on downstream ICs during transients |
| ESD robustness | Withstands ±30 kV contact/air discharge per IEC 61000-4-2 - suitable for front-panel USB/RS-485 ports |
| Low leakage | <0.2 µA at VRM - preserves battery life in always-on IoT sensor nodes |
| MSL Level 1 | Unlimited floor life at ≤30 °C/60% RH - simplifies SMT assembly without baking requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Same VRM (13 V), higher PPP (600 W), but SMB package (surface-mount); VCL = 21.5 V @ 28.3 A | Requires rework of through-hole layout; better thermal performance on copper pour | Select when board space is constrained and automated assembly is preferred |
| P6KE13A | Legacy DO-15 device; lower PPP (600 W), higher VCL (23.0 V @ 26.1 A), wider VBR tolerance (13.7–15.2 V) | Larger clamping margin reduces system-level immunity margin; not rated for 175 °C operation | Acceptable for cost-sensitive legacy designs where thermal headroom exists |
Compared with SMBJ13A and P6KE13A, BZW06-13RL offers tighter VBR tolerance (14.4–16.0 V), lower dynamic resistance (0.427 Ω), and guaranteed 175 °C operation - making it optimal for thermally aggressive, high-reliability industrial power rails.

FAQ
What is the maximum peak pulse current the BZW06-13RL can handle?
The BZW06-13RL sustains 28.6 A peak pulse current under the standard 10/1000 µs waveform at 25 °C ambient. At elevated junction temperatures, its derated capability drops to 24.0 A at 125 °C and 19.5 A at 175 °C, as defined by the PPP vs. Tj curve in Figure 3 of DS0661 Rev 7.
Is the BZW06-13RL suitable for bidirectional signal line protection?
No - BZW06-13RL is unidirectional and intended for DC-biased lines like power rails. For bidirectional protection (e.g., RS-485, USB), ST offers the BZW06-13B variant, which has symmetrical clamping in both polarities and identical VRM/VBR specs but different marking and tape orientation.
Does this TVS diode require heatsinking in typical applications?
Not typically - its DO-15 package achieves ~100 °C/W thermal impedance on standard FR4 with 70 µm copper. Heatsinking is unnecessary for single-pulse events, but adding 1 cm² copper pour per lead reduces Rth(j-a) by ~30%, improving repetitive surge handling in high-duty-cycle applications.
How does the BZW06-13RL compare to Zener diodes for surge protection?
Unlike general-purpose Zeners, BZW06-13RL is optimized for transient absorption: it features lower dynamic resistance (0.427 Ω vs. >5 Ω), faster response (<1 ns), higher surge ratings (600 W vs. <5 W), and guaranteed clamping performance across temperature - making it unsuitable as a voltage regulator but superior for ESD/surge suppression.
