Product details
Overview
P6KE180A A0G from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 180 V, clamps transients to ≤246 V at 2.5 A peak surge current, and maintains ≤1 μA reverse leakage above 154 V standoff voltage - enabling robust ESD and lightning surge protection in automotive lighting control modules.
For engineers reviewing the P6KE180A A0G datasheet, P6KE180A A0G pinout, P6KE180A A0G application, or P6KE180A A0G equivalent, key selection criteria include its DO-15 package compatibility, 175°C junction temperature rating, unidirectional polarity marking, and compliance with AEC-Q101 (via H-suffix variants), making it suitable for industrial power supply input stages and automotive body electronics.
Technical Context
The P6KE180A A0G operates as a silicon avalanche diode with fast response time (<1.0 ps from 0 V to VBR) and low dynamic impedance, ensuring rapid clamping during fast-rising transients such as EFT (IEC 61000-4-4) and ISO 7637-2 pulses. Its unidirectional configuration provides forward conduction capability while blocking reverse current until breakdown.
It delivers 600 W peak pulse power (10/1000 µs waveform) with a maximum clamping voltage of 246 V at 2.5 A, and exhibits a temperature coefficient of VBR of 0.108 %/°C - critical for stable protection across automotive ambient ranges. The device is rated for junction temperatures from –55°C to +175°C and meets UL 94V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 171 V / 189 V at 1 mA test current - defines reliable turn-on threshold under surge conditions |
| VWM | 154 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| VC @ IPP | 246 V at 2.5 A - clamping voltage limiting downstream circuit stress during 10/1000 µs surges |
| PPK | 600 W - peak surge power handling per single 10/1000 µs pulse, derated above 25°C |
| IR @ VWM | ≤1 μA - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ max | +175°C - supports operation in under-hood automotive environments and enclosed industrial enclosures |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with tin-plated leads per J-STD-002 |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking for unidirectional polarity. Leads are pure tin-plated and solderable per J-STD-002; case meets UL 94V-0 flammability rating.

IC Role / Device Role / Timing Role: Localized TVS on 3.3 V/5 V bias rails feeding Gigabit Ethernet magnetics and PHY ICs. Use Value: Fast <1.0 ps response ensures clamping before 100 ps rise-time transients propagate into sensitive analog front-ends. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A | DO-214AA (SMB) package; 600 W rating; VBR = 171–189 V; VC = 246 V @ 2.5 A - identical electrical specs but surface-mount | Requires PCB re-layout for SMT vs. through-hole; better for automated assembly but less suited for high-vibration environments | Select SMBJ180A when board space is constrained and reflow compatibility is required. |
| 1.5KE180A | Same DO-15 package; 1500 W rating; VBR = 171–189 V; VC = 250 V @ 6.0 A - higher power, slightly higher clamping | Overqualified for 600 W needs; larger junction capacitance may affect high-speed signal lines | Choose 1.5KE180A only if legacy 1.5 kW surge immunity (IEC 61000-4-5 Level 4) is mandated. |
Compared with SMBJ180A and 1.5KE180A, the P6KE180A A0G offers optimal balance of through-hole mechanical robustness, 600 W surge capacity, and low-profile DO-15 footprint - ideal for cost-sensitive industrial power supplies where manual assembly or field serviceability matters.

FAQ
What is the maximum clamping voltage of the P6KE180A A0G under standard test conditions?
The P6KE180A A0G has a maximum clamping voltage (VC) of 246 V when subjected to a 2.5 A peak pulse current with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable voltage limiting during surge events - a critical parameter for protecting downstream 200 V-rated components in the P6KE180A A0G's target applications.
Is the P6KE180A A0G suitable for automotive applications?
The P6KE180A A0G itself is not AEC-Q101 qualified; however, the functionally identical P6KE180AH variant (same electrical specs, H-suffix) is AEC-Q101 certified. Engineers specifying the P6KE180A A0G for automotive use should verify qualification status with Taiwan Semiconductor's official documentation and consider P6KE180AH for production-grade automotive designs requiring formal qualification.
What does the 'A0G' suffix indicate in P6KE180A A0G?
The 'A0G' suffix in P6KE180A A0G denotes two attributes: 'A' indicates tighter VBR tolerance (±5% vs. ±10% for non-A parts), and '0G' specifies green (halogen-free) molding compound compliant with IEC 61249-2-21. This suffix also identifies the packaging format: 1,500 units per ammo box - distinct from tape-and-reel variants like P6KE180AH.
Can the P6KE180A A0G be used in bidirectional configurations?
No - the P6KE180A A0G is a unidirectional TVS diode, indicated by its single cathode band marking and specified VBR/VWM values for reverse bias only. For bidirectional protection, Taiwan Semiconductor offers the P6KE180CA variant (with 'C' or 'CA' suffix), which provides symmetrical clamping in both polarities and is electrically characterized in both directions.
What is the junction-to-ambient thermal resistance (RθJA) of the P6KE180A A0G in standard mounting?
Taiwan Semiconductor does not publish RθJA for the P6KE180A A0G in the provided datasheet. However, based on DO-15 package thermal performance benchmarks and steady-state power dissipation (PD = 5 W at TA = 75°C with 9.5 mm lead length), typical RθJA is estimated at ~50°C/W under JEDEC-standard 5 × 5 mm copper pad mounting - sufficient for intermittent surge duty but not continuous 5 W operation without additional heatsinking.
