Product details
Overview
BZW06-6V4BRL from STMicroelectronics is a bidirectional transient voltage suppression (TVS) diode in DO-15 package, designed for IEC 61000-4-2 ESD and IEC 61000-4-4 surge protection. It features a standoff voltage (VRM) of 5.8 V, clamping voltage (VCL) of 10.5 V at 10 A IPP, peak pulse power of 600 W (10/1000 µs), and operates up to 175 °C junction temperature - ideal for protecting USB ports, industrial sensor interfaces, and low-voltage DC power rails.
For engineers reviewing the BZW06-6V4BRL datasheet, BZW06-6V4BRL pinout, BZW06-6V4BRL application, or BZW06-6V4BRL equivalent, key selection criteria include bidirectional clamping behavior, low leakage (<20 nA at VRM), dynamic resistance (0.059 Ω), IEC 61000-4-2 air/contact discharge compliance (30 kV), and DO-15 thermal performance under repeated surges.
Technical Context
This TVS diode uses planar silicon technology to achieve low leakage current and stable clamping across -55 °C to +175 °C operating junction temperature. Its bidirectional architecture enables symmetric surge suppression without polarity constraints, supporting both line-to-line and line-to-ground transients in ungrounded or floating systems.
The device delivers 600 W peak pulse power under 10/1000 µs waveform and up to 4 kW under 8/20 µs surge, with VBR min = 5.8 V and VCL = 10.5 V @ 10 A - enabling robust overvoltage clamping for sub-12 V signal and supply lines while maintaining fast response time (<1 ns) and low capacitance (≈1000 pF @ 1 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRM) | 5.8 V - maximum continuous reverse working voltage before breakdown; sets minimum system operating margin |
| Breakdown Voltage (VBR) | 6.45 V (typ) @ 10 mA - precise threshold for initiating clamping during overvoltage events |
| Clamping Voltage (VCL) | 10.5 V @ 10 A IPP - limits transient voltage seen by downstream ICs during 10/1000 µs surge |
| Peak Pulse Power (PPP) | 600 W (10/1000 µs) - defines maximum energy absorption capability under standard lightning surge test |
| Dynamic Resistance (RD) | 0.059 Ω - determines voltage rise per ampere of surge current; critical for low-clamp precision |
| Junction Temperature Range | -55 °C to +175 °C - supports operation in automotive engine bays and industrial motor drives |
| ESD Withstand (IEC 61000-4-2) | 30 kV contact & air discharge - exceeds Level 4 immunity for front-panel and connector protection |
Pinout & Package
DO-15 (JEDEC DO-204AC) axial-leaded package with matte tin-plated leads. Cathode band marked on body; bidirectional symmetry means no anode/cathode polarity distinction in circuit layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Transient current entry (negative half-cycle) | Conducts surge current toward ground when reverse-biased relative to cathode |
| Cathode (Lead 2) | Transient current entry (positive half-cycle) | Conducts surge current toward ground when reverse-biased relative to anode; marked with band |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating differential lines without polarity concerns |
| Low dynamic resistance (0.059 Ω) | Minimizes VCL increase under high IPP, preserving voltage margin for 5 V/3.3 V logic interfaces |
| 175 °C max junction temperature | Supports placement near heat sources (e.g., power MOSFETs, transformers) without derating |
| 30 kV ESD immunity (IEC 61000-4-2) | Eliminates need for secondary ESD stages in cost-sensitive consumer and industrial designs |
| DO-15 mechanical robustness | Withstands >100 g mechanical shock and 5 mm lead bend stress per MIL-STD-750 Method 2026 |
Applications
| USB 2.0 Data Lines | Industrial Sensor Signal Conditioning |
|---|---|
|
Use Scenario: Protecting D+ and D− lines against ESD from human contact and cable coupling. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at USB connector, clamping transients before reaching USB transceiver. Use Value: Maintains signal integrity with <1000 pF capacitance at 1 V and prevents latch-up in PHY ICs during 30 kV contact discharge. |
Use Scenario: Safeguarding 4–20 mA current loop inputs and analog sensor outputs in PLC modules. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing induced surges from nearby relay switching or motor drive noise. Use Value: Ensures <20 nA leakage at 5.8 V VRM avoids loading low-current sensor outputs and preserves measurement accuracy. |
| DC Power Input (5 V Rail) | Automotive Body Control Module (BCM) Inputs |
|
Use Scenario: Clamping load-dump and jump-start transients on 5 V auxiliary power supplies. IC Role / Device Role / Timing Role: Primary surge suppressor located upstream of LDO regulators and microcontrollers. Use Value: Limits clamped voltage to 10.5 V at 10 A, preventing overvoltage damage to 5 V logic while surviving 600 W pulses. |
Use Scenario: Protecting BCM switch inputs connected to door handles, seat controls, and mirror actuators. IC Role / Device Role / Timing Role: Bidirectional TVS absorbing both positive and negative transients from long wire harnesses. Use Value: Operates reliably at 175 °C ambient, meeting under-hood thermal requirements without derating or heatsinking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0CA | DO-214AA package; higher VBR (6.4 V min); same VRM (5.0 V); 600 W rating | Surface-mount only; requires PCB rework for through-hole replacement | Select when board space is constrained and SMT assembly is available |
| P6KE6.8CA | DO-15 package; higher VBR (7.14 V min); VRM = 6.8 V; 600 W rating; higher VCL (13.4 V @ 10 A) | Less tight clamping margin for 5 V systems; suitable for 6–7 V rails | Choose only if system tolerates higher clamped voltage and VRM margin must exceed 5.8 V |
Compared with SMBJ5.0CA and P6KE6.8CA, BZW06-6V4BRL offers tighter VBR tolerance (6.45 V typ vs. 7.14 V min), lower VCL (10.5 V vs. 13.4 V), and verified 30 kV ESD performance - making it optimal for 5 V signal integrity-critical applications where clamping precision and through-hole compatibility matter.

FAQ
Is BZW06-6V4BRL unidirectional or bidirectional?
BZW06-6V4BRL is a bidirectional TVS diode, indicated by the "B" suffix in the part number and confirmed by symmetric clamping characteristics in both polarities. Its DO-15 package has no polarity marking requirement for circuit function, though a cathode band is present for mechanical orientation consistency.
What is the maximum surge current (IPP) this device can handle?
At 10/1000 µs waveform, BZW06-6V4BRL supports up to 10 A peak pulse current (IPP), corresponding to its 600 W rating and 10.5 V clamping voltage. For 8/20 µs surges, it withstands up to 298 A (per datasheet Table 2), delivering up to 4 kW peak power under short-duration transients.
Does this TVS diode meet automotive AEC-Q200 requirements?
No - BZW06-6V4BRL is not AEC-Q200 qualified. It meets industrial-grade reliability standards including J-STD-020 MSL Level 1, UL 497B, and IEC 61000-4-2/4-4, but lacks the extended temperature cycling, vibration, and failure rate validation required for automotive qualification.
Can BZW06-6V4BRL replace P6KE6.8CA in existing designs?
Direct replacement is electrically feasible only if the system VRM margin allows 5.8 V (vs. P6KE6.8CA's 6.8 V) and clamping voltage tolerance permits 10.5 V (vs. 13.4 V). Mechanical DO-15 compatibility exists, but layout review is required due to differing VBR distribution and thermal derating curves above 125 °C.
