Product details
Overview
BZW06-19BRL from STMicroelectronics is a bidirectional transient voltage suppression diode in DO-15 package, designed for IEC 61000-4-2 ESD protection (30 kV air/contact discharge) and IEC 61000-4-4 surge immunity (4 kV level 4). It features 19 V stand-off voltage (VRM), 21.2 V minimum breakdown voltage (VBR), and clamps to ≤33.7 V at 12.0 A peak pulse current (IPP) under 10/1000 µs waveform. Used in AC power input stages of industrial power supplies and telecom line interfaces.
For engineers reviewing the BZW06-19BRL datasheet, BZW06-19BRL pinout, BZW06-19BRL application, or BZW06-19BRL equivalent, key selection criteria include clamping voltage at rated IPP, junction temperature derating above 25 °C, bidirectional polarity for AC-coupled lines, and DO-15 mechanical compatibility with high-density PCB layouts.
Technical Context
This TVS diode employs planar silicon junction technology optimized for low leakage (<0.2 µA at VRM) and stable VBR over temperature (αT = 10 × 10⁻⁴ /°C). Its bidirectional structure enables symmetrical clamping on both polarities without external polarity management.
It delivers 600 W peak pulse power (10/1000 µs) at 25 °C ambient, derating to 300 W at Tj = 175 °C. Dynamic resistance (RD) is 1.01 Ω at 10/1000 µs, ensuring predictable voltage rise under fast transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRM) | 19 V - Maximum continuous reverse working voltage before conduction begins |
| Breakdown Voltage (VBR) | 21.2–23.6 V at 1 mA - Confirmed turn-on threshold for reliable overvoltage triggering |
| Clamping Voltage (VCL) | ≤33.7 V at IPP = 12.0 A (10/1000 µs) - Limits downstream component stress during surge events |
| Peak Pulse Power (PPP) | 600 W (10/1000 µs, Tamb = 25 °C) - Sustains defined surge energy without failure |
| Junction Temperature Range | −55 °C to +175 °C - Enables operation in harsh industrial and automotive under-hood environments |
| ESD Withstand | 30 kV contact & air discharge (IEC 61000-4-2) - Exceeds level 4 immunity requirements |
| Surge Immunity | 4 kV (IEC 61000-4-4 level 4) - Protects against repetitive fast transients on AC mains or signal lines |
Pinout & Package
DO-15 (JEDEC DO-204AC) axial-leaded package with matte tin-plated leads. Body length 6.05–6.75 mm, lead diameter 0.71–0.88 mm, overall length 26–31 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Current entry terminal in forward bias | Connected to lower-potential side of protected line; bidirectional symmetry means no fixed anode/cathode polarity |
| Cathode (K) | Current exit terminal in forward bias | Connected to higher-potential side; marking band denotes cathode end for unidirectional variants; BZW06-19BRL has no polarity marking due to bidirectional construction |
Key Features
| Feature | Design Value |
|---|---|
| High-Temperature Operation | Rated up to 175 °C junction temperature - supports placement near heat-generating components in SMPS designs |
| Low Leakage Current | ≤0.2 µA at VRM = 19 V - minimizes standby power loss and avoids false triggering in high-impedance circuits |
| Stable Breakdown Over Temperature | Temperature coefficient αT = 10 × 10⁻⁴ /°C - ensures predictable VBR shift across full operating range |
| Robust Surge Handling | 4 kW capability at 8/20 µs - accommodates lightning-induced surges in telecom and building automation systems |
Applications
| AC Power Input Protection | Telecom Line Interface |
|---|---|
Use Scenario: AC mains input stage of industrial switch-mode power supplies exposed to lightning-induced surges and switching transients. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed across L-N or L/N-PE to limit transient overvoltages before rectification. Use Value: Clamps 4 kV IEC 61000-4-4 surges to ≤33.7 V, protecting bridge rectifier and primary-side controller ICs from overvoltage damage. | Use Scenario: Protection of analog telephone line interface circuits (e.g., SLIC, codec) against ESD and induced surges. IC Role / Device Role / Timing Role: Bidirectional shunt device across tip/ring pair to suppress ±30 kV ESD and fast transients without polarity constraints. Use Value: Low dynamic resistance (1.01 Ω) ensures rapid clamping response, preserving signal integrity while meeting GR-1089-CORE surge requirements. |
| Industrial Sensor Signal Conditioning | Building Automation Bus Lines |
Use Scenario: Protection of 4–20 mA current loop inputs in PLC analog modules subjected to field wiring ESD and inductive kickback. IC Role / Device Role / Timing Role: Bidirectional TVS placed across input terminals to absorb transients while maintaining loop accuracy. Use Value: 19 V VRM matches typical loop supply headroom; <0.2 µA leakage avoids measurement error in high-precision sensing paths. | Use Scenario: Surge protection on RS-485 or KNX bus lines in HVAC control panels and lighting systems installed in electrically noisy buildings. IC Role / Device Role / Timing Role: Bidirectional clamp between differential pair and ground to suppress common-mode transients without disrupting data timing. Use Value: 600 W 10/1000 µs rating handles repeated surges from nearby motor switching, extending bus transceiver lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ19CA | DO-214AA package, 600 W rating, VBR = 21.1–23.3 V, VCL = 32.4 V @ 12.3 A | Surface-mount footprint; lower thermal resistance but requires reflow-compatible layout | Select when board space is constrained and automated assembly is required |
| P6KE19CA | DO-15 package, 600 W rating, VBR = 20.0–22.2 V, VCL = 33.2 V @ 12.1 A, higher leakage (5.0 µA max) | Legacy design; wider VBR tolerance and higher IR reduce precision in low-power systems | Acceptable for cost-sensitive legacy replacements where leakage <1 µA is not critical |
Compared with SMBJ19CA and P6KE19CA, BZW06-19BRL offers tighter VBR tolerance (±5%), lower leakage (≤0.2 µA), and superior high-temperature stability (175 °C Tj max), making it preferred for modern industrial power and communication interfaces demanding long-term reliability.

FAQ
What is the maximum clamping voltage of BZW06-19BRL at 12.0 A (10/1000 µs)?
The maximum clamping voltage (VCL) is 33.7 V at 12.0 A peak pulse current under 10/1000 µs waveform, measured at Tamb = 25 °C. This value increases linearly with junction temperature using αT = 10 × 10⁻⁴ /°C, reaching ~37.1 V at Tj = 175 °C.
Is BZW06-19BRL unidirectional or bidirectional?
BZW06-19BRL is a bidirectional TVS diode, indicated by the "B" suffix in the part number. It provides symmetrical clamping for both positive and negative transients without polarity sensitivity, making it suitable for AC-coupled lines like telecom interfaces and AC mains inputs.
What is the leakage current specification at VRM = 19 V?
The maximum reverse leakage current (IRM) is 0.2 µA at VRM = 19 V and Tamb = 25 °C. This ultra-low leakage ensures minimal impact on high-impedance circuits such as 4–20 mA sensor loops and precision analog front-ends.
Can BZW06-19BRL be used in wave soldering processes?
Yes - BZW06-19BRL is qualified for wave soldering per AN5088 recommendations. The DO-15 package withstands lead temperature up to 260 °C for 10 seconds at 5 mm from case. Preheating and dwell time must comply with JEDEC J-STD-002 to avoid thermal stress on the silicon junction.
