Product details
Overview
BZW06-15B from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, rated for 600W peak pulse power at 10/1000μs, with 15.3V working stand-off voltage, 17.1–18.9V breakdown voltage, and clamping voltage of 25.2V at 24.0A. It protects automotive and industrial circuits against ESD, EFT, and inductive switching transients.
For engineers reviewing the BZW06-15B datasheet, BZW06-15B pinout, BZW06-15B application, or BZW06-15B equivalent, key selection criteria include unidirectional/bidirectional polarity confirmation, 600W surge rating at 10/1000μs, DO-15 mechanical compatibility, junction temperature range (−55°C to +175°C), and AEC-Q101 qualification status.
Technical Context
The BZW06-15B operates as a voltage-clamped overvoltage protection device, leveraging avalanche breakdown to divert transient energy away from sensitive downstream circuitry. Its bidirectional configuration enables symmetrical clamping for AC-coupled or floating signal lines, with typical reverse leakage <1μA at 15.3V and dynamic impedance low enough to sustain sub-25.2V clamping under 24A 10/1000μs pulses.
Thermal performance is defined by RθJL = 60°C/W and RθJA = 100°C/W, supporting operation up to TJ = 175°C. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements, with pure tin-plated leads compliant to J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VWM | 15.3 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (min/typ/max) | 17.1 / 18.0 / 18.9 V - Breakdown voltage range at 1 mA test current; defines clamping onset threshold |
| VC @ IPPM | 25.2 V @ 24.0 A - Clamping voltage during 10/1000μs surge; limits stress on protected ICs |
| PPK | 600 W - Peak pulse power handling capability per non-repetitive 1 ms pulse |
| TJ Range | −55°C to +175°C - Operating junction temperature range enabling under-hood automotive use |

Pinout & Package
DO-204AC (DO-15) is an axial-leaded, molded plastic package with cathode band marking for unidirectional variants; BZW06-15B is bidirectional and therefore has no polarity marking - both terminals are functionally identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode | Reversible transient conduction path | Both terminals serve as symmetrical avalanche junctions; no fixed anode/cathode assignment in bidirectional mode |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified option available | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard |
| Fast response time | Typically <5.0 ns for bidirectional mode - ensures clamping activation before transient energy damages downstream logic |
| Low dynamic impedance | Enables stable 25.2 V clamping across 24 A surge, minimizing voltage overshoot during fast-rising transients |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS directives - supports green manufacturing and end-of-life recycling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | Same DO-214AA (SMB) package; 600W rating; VBR = 16.7–18.5V; slightly lower clamping (24.4V @ 24.4A) | Surface-mount only; unsuitable for through-hole legacy designs | Select when board space is constrained and reflow assembly is used |
| P6KE15CA | DO-15 package; 600W rating; VBR = 15.2–16.8V; higher clamping (25.5V @ 23.5A); no AEC-Q101 option | Broader VBR tolerance but lacks automotive qualification path | Select for cost-sensitive industrial applications where AEC-Q101 is not required |
Compared with SMBJ15CA and P6KE15CA, the BZW06-15B offers identical DO-15 form factor and AEC-Q101 qualification - critical for automotive replacement programs - while maintaining tighter VBR tolerance (17.1–18.9V) and lower clamping variance across production lots.

FAQ
What is the polarity configuration of BZW06-15B?
The BZW06-15B is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients without defined anode or cathode terminals. Unlike unidirectional variants (e.g., BZW06-15), it lacks a cathode band marking and functions identically regardless of terminal orientation in the circuit.
Does BZW06-15B meet AEC-Q101 qualification?
The base BZW06-15B part number is not automatically AEC-Q101 qualified; qualification applies only to versions marked with the "H" suffix (e.g., BZW06-15BH). Always verify the full ordering code on the reel label or certificate of conformance - BZW06-15B itself is rated for automotive use but requires the "H" variant for formal AEC-Q101 compliance.
What is the maximum clamping voltage of BZW06-15B under standard test conditions?
The BZW06-15B exhibits a maximum clamping voltage (VC) of 25.2 V when subjected to a 10/1000 μs waveform at a peak pulse current (IPPM) of 24.0 A. This value is measured per JEDEC standards and represents the upper limit of voltage seen by protected circuitry during worst-case surge events.
Can BZW06-15B be used in surface-mount designs?
No - BZW06-15B uses the DO-204AC (DO-15) axial-leaded through-hole package and is not compatible with surface-mount assembly processes. For SMT equivalents, consider SMBJ15CA (DO-214AA) or SMCJ15CA (DO-214AB), which share similar electrical ratings but differ in thermal and mechanical behavior.
What is the junction-to-lead thermal resistance (RθJL) of BZW06-15B?
The junction-to-lead thermal resistance (RθJL) of BZW06-15B is 60°C/W, measured under standard lead length conditions (9.5 mm). This parameter governs heat transfer from the silicon die to the PCB copper via the leads and directly impacts sustained surge repetition rate and derating at elevated ambient temperatures.
