Product details
Overview
BZW06-58BRL from STMicroelectronics is a bidirectional transient voltage suppression (TVS) diode in DO-15 package, designed for high-energy ESD and surge protection in power rails and signal lines. It features a 58 V stand-off voltage (VRM), 92 V clamping voltage (VCL) at 6.5 A peak pulse current (IPP), 600 W peak pulse power (10/1000 µs), and operates up to 175 °C junction temperature - ideal for industrial power supplies and telecom interface protection.
For engineers reviewing the BZW06-58BRL datasheet, BZW06-58BRL pinout, BZW06-58BRL application, or BZW06-58BRL equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, unidirectional/bidirectional polarity match, thermal derating above 25 °C, and IEC 61000-4-2/4-4 compliance level verification.
Technical Context
This bidirectional TVS diode uses planar silicon junction technology to achieve low leakage (<0.2 µA at VRM), stable breakdown behavior across -55 °C to +175 °C, and predictable clamping with dynamic resistance (RD) of 3.17 Ω under 10/1000 µs surge. Its symmetrical avalanche structure enables equal clamping in both polarities without external biasing.
The device complies with IEC 61000-4-2 (±30 kV contact/air discharge) and IEC 61000-4-4 Level 4 (4 kV), delivering robust protection against fast transients while maintaining low capacitance (<100 pF at 1 V) - critical for high-speed data lines and switching power supply feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRM) | 58 V - maximum continuous reverse working voltage before significant leakage; sets minimum system rail voltage compatibility. |
| Breakdown Voltage (VBR) | 64.6–71.4 V at 1 mA - defines onset of avalanche conduction; tight tolerance ensures consistent trigger timing. |
| Clamping Voltage (VCL) | 92.0 V at 6.5 A (10/1000 µs) - peak voltage seen by protected circuit during surge; determines safe margin over IC absolute max rating. |
| Peak Pulse Power (PPP) | 600 W (10/1000 µs) - energy-handling capability at 25 °C; derates to ~300 W at Tj = 175 °C per Figure 3. |
| Dynamic Resistance (RD) | 3.17 Ω - slope of VCL vs. IPP curve; lower RD improves clamping linearity and reduces voltage overshoot under high-current surges. |
| Junction Temperature Range | -55 °C to +175 °C - enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
| ESD Rating | ±30 kV (IEC 61000-4-2, contact & air) - exceeds Level 4; eliminates need for secondary ESD stages in many front-end designs. |
Pinout & Package
DO-15 (JEDEC DO-204AC) axial-leaded package with matte tin-plated leads; cathode band marked on body. Leads spaced 26–31 mm, body diameter 2.95–3.53 mm, length 6.05–6.75 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge current entry (negative polarity) | Accepts transient energy during negative-going events; forms symmetrical path with cathode in bidirectional operation. |
| Cathode | Surge current entry (positive polarity) | Accepts transient energy during positive-going events; marked by band; enables dual-polarity clamping without polarity awareness. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional surge suppression | Enables single-device protection of AC-coupled or floating signal lines without polarity-sensitive layout constraints. |
| High-temperature operation (Tj ≤ 175 °C) | Supports placement near heat sources (e.g., MOSFETs, transformers) without derating penalties beyond datasheet curves. |
| Low dynamic resistance (3.17 Ω) | Minimizes clamping voltage rise under high di/dt surges, preserving margin for 72 V-rated downstream components. |
| UL 497B certified (QVGQ2.E136224) | Validates suitability for primary-side telecom and industrial data line protection per safety standards. |
| IEC 61000-4-4 Level 4 compliance | Guarantees immunity to 4 kV ring wave surges on power inputs, reducing need for additional filtering or staged protection. |
Applications
| Industrial Power Supply Input Protection | Telecom Line Interface Protection |
|---|---|
Use Scenario: 24–48 V DC input stage of programmable logic controllers exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Primary surge clamp on main DC bus; absorbs 600 W pulses within 1 ms to prevent upstream fuse blowout and downstream regulator damage. Use Value: Clamps to 92 V - safely below 100 V absolute max rating of common DC-DC controllers (e.g., LM5017), eliminating need for series Zener or crowbar circuits. | Use Scenario: RS-485 transceiver bus lines in outdoor base stations subjected to lightning-induced surges and ESD events. IC Role / Device Role / Timing Role: Bidirectional shunt protector on differential pair; responds within <1 ns to limit voltage excursion during ±30 kV ESD strikes. Use Value: Low 3.17 Ω RD ensures sub-100 V clamping even at 10 A surge peaks, preserving signal integrity and preventing transceiver latch-up. |
| Automotive Body Control Module (BCM) Power Rail | AC-DC Adapter Secondary-Side Protection |
Use Scenario: 12 V battery-fed microcontroller power domain in BCM modules operating under ISO 7637-2 pulse 1/2a/5a conditions. IC Role / Device Role / Timing Role: Standoff-rated TVS on VCC rail; clamps load dump spikes (up to 120 V) while maintaining <0.2 µA leakage at 58 V. Use Value: 58 V VRM provides 10 V margin above nominal 48 V system (2×12 V), enabling direct integration without voltage divider networks. | Use Scenario: Output rectifier rail of 24 V/5 A SMPS adapter where output must survive accidental short-to-line faults. IC Role / Device Role / Timing Role: Secondary-side surge limiter; clamps flyback transformer leakage energy and cross-regulation overshoots. Use Value: 175 °C Tj rating allows mounting directly on PCB near hot-spot rectifiers without thermal runaway risk. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | Bidirectional, same VRM (58 V), but SMB package (surface-mount); 600 W rating at 25 °C, RD = 2.8 Ω | Requires PCB rework for SMT assembly; better thermal performance on copper pour but no axial lead option | Select when board space is constrained and automated assembly is used; verify pad thermal relief for 175 °C operation. |
| P6KE58CA | Bidirectional, same VRM, DO-15 package, but lower PPP (600 W) and higher VCL (93.6 V at 6.4 A); RD = 3.5 Ω | Legacy part with wider VBR tolerance (64.4–76.7 V); less precise clamping under temperature variation | Select only for cost-sensitive legacy replacements; avoid where tight VCL margin is required (e.g., 75 V-rated ICs). |
Compared with SMBJ58CA and P6KE58CA, BZW06-58BRL offers superior thermal stability (175 °C Tj), tighter VBR (±5%), and lower RD (3.17 Ω), making it preferred for high-reliability industrial and automotive applications where long-term parameter drift must be minimized.

FAQ
What is the difference between BZW06-58B and BZW06-58BRL?
BZW06-58B is the base part number indicating a bidirectional 58 V TVS diode in DO-15 package. The "RL" suffix denotes tape-and-reel packaging (6000 units per reel), whereas non-RL versions ship in ammopack (1000 units). Electrical and thermal specifications are identical; only packaging and quantity differ.
Can BZW06-58BRL be used in place of a unidirectional TVS?
No - BZW06-58BRL is strictly bidirectional and lacks anode/cathode polarity distinction in function. Substituting it for a unidirectional TVS (e.g., BZW06-58RL) in DC-biased circuits may cause unintended conduction during normal operation. Always match device polarity to circuit topology and bias conditions.
How does junction temperature affect clamping voltage?
VCL increases linearly with junction temperature at 10.4 × 10⁻⁴/°C (αT). At 125 °C, VCL rises ~1.04 V above its 25 °C value (92.0 V → ~93.0 V). This shift must be included when verifying margin against protected IC absolute maximum ratings at elevated ambient temperatures.
Is lead-free soldering supported?
Yes - BZW06-58BRL complies with J-STD-020 MSL Level 1 and supports lead-free reflow per ST's recommended profile (peak 240–245 °C, 60–90 s above 220 °C). Matte tin plating ensures reliable wetting and intermetallic formation without voiding or dewetting risks.
