Product details
Overview
BZW06-188 from Taiwan Semiconductor is a unidirectional 600W Transient Voltage Suppressor (TVS) diode with a working stand-off voltage of 188 V, breakdown voltage range 209–231 V at 1 mA, and clamping voltage of 301 V at 2.0 A (10/1000 μs). It features low dynamic impedance, <1 μA reverse leakage above 10 V, and AEC-Q101 qualification for automotive-grade surge protection in power supply rails and I/O interfaces.
For engineers reviewing the BZW06-188 datasheet, BZW06-188 pinout, BZW06-188 application, or BZW06-188 equivalent, key selection criteria include its DO-204AC (DO-15) package, 175°C maximum junction temperature, fast response time (<1.0 ps from 0 V to VBR), and compliance with RoHS and halogen-free standards per IEC 61249-2-21.
Technical Context
The BZW06-188 operates as a unidirectional avalanche diode, designed to clamp transient overvoltages above its VWM (188 V) by entering avalanche breakdown. Its thermal design relies on RθJL = 60°C/W and RθJA = 100°C/W, enabling reliable operation up to TJ = 175°C under pulsed conditions.
It delivers 600 W peak pulse power at 10/1000 μs waveform with a clamping ratio (VC/VBR) of ~1.37, supported by low junction capacitance (typ. <100 pF at 1 MHz) and temperature coefficient of VBR = 0.108 %/°C - critical for stable clamping across automotive ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 188 V - maximum continuous reverse operating voltage before conduction begins |
| VBR @ 1 mA | 209–231 V - guaranteed avalanche onset range, defining minimum system overvoltage threshold |
| VC @ 2.0 A (10/1000 μs) | 301 V - maximum clamped voltage during 600 W surge, limiting downstream stress |
| PPK | 600 W - peak transient power handling capability per non-repetitive 1 ms pulse |
| IR @ VWM | <1 μA - minimal leakage current ensures negligible standby power loss and signal integrity |
| TJ max | 175 °C - enables deployment in under-hood automotive environments without derating |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with UL 94V-0 molding compound |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded plastic case with cathode band marking for unidirectional polarity. Leads are pure tin-plated, solderable per J-STD-002, and pass JESD 201 Class 2 whisker test. Weight ≈ 0.400 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path) in unidirectional TVS configuration |
| Cathode | Avalanche clamping terminal | Connected to protected line (e.g., 188 V rail); cathode band identifies polarity for correct PCB orientation |

Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs against load dump (ISO 16750-2) and alternator ripple-induced spikes. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground to clamp transients before they reach MCU power pins or LDO inputs. Use Value: Limits voltage excursion to ≤301 V during 600 W surges, preserving 3.3 V/5 V regulator input stage integrity and avoiding latch-up. | Use Scenario: Shielding digital input channels of programmable logic controllers from inductive kickback (e.g., relay coil de-energization). IC Role / Device Role / Timing Role: TVS mounted at field-wire entry point to absorb 10/1000 μs energy bursts before reaching optocoupler or Schmitt trigger inputs. Use Value: Prevents false triggering and long-term parametric drift in input conditioning circuits by suppressing >1 kV transients down to safe levels. |
| LED Driver Overvoltage Clamp | Telecom Line Surge Suppression |
Use Scenario: Safeguarding constant-current LED drivers in streetlight systems exposed to lightning-induced surges on AC mains lines. IC Role / Device Role / Timing Role: Placed across driver output terminals to clamp voltage spikes caused by open-circuit faults or grid switching transients. Use Value: Maintains LED string continuity by limiting transient voltage to 301 V, avoiding MOSFET drain-source breakdown and driver IC damage. | Use Scenario: Front-end protection for Ethernet PHYs or RS-485 transceivers connected to outdoor cabling susceptible to induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS on VCC or signal line referenced to local ground, absorbing common-mode transients per IEC 61000-4-5. Use Value: Enables robust 10/1000 μs immunity up to 600 W without adding series impedance that would degrade signal rise time or jitter. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ188A | Same VWM (188 V), but lower PPK = 600 W in SMB package; slightly higher VC = 305 V at 2.0 A | SMB surface-mount footprint requires PCB redesign; better suited for space-constrained board-level protection | Select when automated assembly and smaller board area outweigh axial-lead serviceability needs |
| P6KE188A | Same DO-15 package and VWM, but lower PPK = 600 W (same rating), higher VC = 313 V at 2.0 A, no AEC-Q101 qualification | Lacks automotive qualification; suitable for industrial/commercial use only | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with SMBJ188A and P6KE188A, the BZW06-188 offers identical surge rating and superior automotive qualification (AEC-Q101), while maintaining the proven reliability and thermal performance of the DO-204AC axial package - making it optimal for high-reliability replacement and legacy-compatible upgrades.

FAQ
What is the maximum clamping voltage of the BZW06-188 under standard test conditions?
The BZW06-188 has a maximum clamping voltage (VC) of 301 V when subjected to a 10/1000 μs surge current of 2.0 A, as specified in the manufacturer's electrical characteristics table. This value defines the upper voltage limit imposed on protected circuitry during transient events and is measured at TA = 25°C with defined pulse waveform and test setup per JEDEC standards.
Is the BZW06-188 suitable for automotive applications?
Yes, the BZW06-188 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and infotainment systems. Its 175°C maximum junction temperature, robust DO-204AC construction, and validated surge performance under ISO 7637-2 and ISO 16750-2 conditions make it appropriate for under-hood and chassis-mounted deployments.
What is the reverse leakage current of the BZW06-188 at its working stand-off voltage?
The BZW06-188 exhibits a maximum reverse leakage current (IR) of 1 μA when biased at its rated working stand-off voltage (VWM) of 188 V, measured at TA = 25°C. This low leakage ensures minimal power loss and avoids interference with high-impedance sensing or reference circuits connected to the protected node.
Does the BZW06-188 have bidirectional variants, and how do they differ?
Yes - the BZW06-188B is the bidirectional variant of the BZW06-188. While both share identical VWM (188 V), VBR (209–231 V), and PPK (600 W), the BZW06-188B supports symmetrical clamping for AC-coupled or floating signal lines, whereas the unidirectional BZW06-188 is optimized for DC rail-to-ground protection with cathode-marked polarity.
What packaging options are available for the BZW06-188?
The BZW06-188 is supplied in DO-204AC (DO-15) package with two standard packing formats: 3,500 units per tape-and-reel (standard code BZW06-188) and 1,500 units per ammo box (code BZW06-188A0G). Both versions feature pure tin-plated leads compliant with J-STD-002 and meet JESD 201 Class 2 whisker resistance requirements.
