Product details
Overview
P6KE180A from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 180V nominal breakdown voltage (VBR min/max: 171V–189V), 154V stand-off voltage (VWM), clamps to ≤246V at 2.5A peak surge current (IPP), and exhibits <1μA reverse leakage at VWM. It is used in automotive body electronics, industrial PLC I/O modules, and AC/DC adapter input stages to absorb lightning-induced surges and inductive switching transients.
For engineers reviewing the P6KE180A datasheet, P6KE180A pinout, P6KE180A application, or P6KE180A equivalent, key selection criteria include its DO-204AC (DO-15) axial package, unidirectional polarity with cathode band marking, 175°C maximum junction temperature, and compliance with AEC-Q101 (H-suffix variant) for automotive-grade reliability - all critical for high-surge industrial and transportation systems.
Technical Context
The P6KE180A operates as a silicon avalanche diode with fast response time (<1.0ps from 0V to VBR), low dynamic impedance, and stable clamping under 10/1000μs surge waveforms. Its unidirectional configuration enables asymmetric protection - blocking reverse conduction while clamping positive transients above VBR.
Thermal derating follows a linear curve above 25°C ambient, maintaining 600W peak pulse power only at TA ≤25°C and reducing to ~300W at 75°C. The device's junction capacitance is not specified for P6KE180A but remains below 100pF across the series at 1MHz and VR=0V, supporting moderate-speed signal line protection without excessive loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 154 V - Maximum continuous DC or RMS voltage the device blocks without significant leakage; defines safe operating margin below clamping threshold. |
| VBR (min/max) | 171 V / 189 V - Breakdown occurs within this range at 1mA test current; ensures predictable turn-on during overvoltage events. |
| VC @ IPP | 246 V @ 2.5 A - Clamped voltage during 10/1000μs surge; determines maximum stress imposed on downstream circuitry. |
| PPK | 600 W - Peak non-repetitive surge power handling capability per 10/1000μs waveform; defines single-event robustness. |
| IR @ VWM | <1 μA - Reverse leakage at rated stand-off voltage; ensures minimal standby power loss and signal integrity in high-impedance circuits. |
| TJ max | 175 °C - Maximum allowable junction temperature; supports operation in under-hood automotive and enclosed industrial environments. |
| Package | DO-204AC (DO-15) - Axial-leaded, epoxy-molded package with UL 94V-0 flammability rating and pure tin-plated leads compliant with J-STD-002 solderability. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, cathode-indicated by band marking. Leads are pure tin-plated and solderable per J-STD-002. Device is mechanically polarized - cathode band denotes the terminal connected to the N-side of the avalanche junction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Low-side reference node | Connected to ground or low-voltage rail; forms return path during clamping conduction. |
| Cathode (banded end) | Protected line input | Connected to the line being protected (e.g., +12V rail); avalanche conduction initiates here during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| 600W surge rating (10/1000μs) | Enables single-event suppression of high-energy transients such as ISO 7637-2 Pulse 5a (load dump) in 12V automotive systems. |
| Clamping voltage ≤246V at 2.5A | Limits voltage overshoot to safe levels for 200V-rated capacitors and MOSFETs downstream of the protected rail. |
| AEC-Q101 qualified (P6KE180AH variant) | Validated for automotive under-hood applications including engine control units and lighting drivers requiring zero-failure reliability. |
| UL 94V-0 molding compound | Prevents flame propagation in safety-critical enclosures, satisfying IEC 62368-1 and UL 62368-1 end-equipment requirements. |

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 (Bourns) | Same 180V nominal, DO-214AA (SMB) surface-mount package; 600W rating; slightly higher VC (259V @ 2.4A). | Requires PCB re-layout for SMT assembly; better thermal performance in high-density layouts but lacks axial lead flexibility for through-hole prototyping. | Select SMBJ180A when migrating to automated SMT production and board space is constrained. |
| 1.5KE180A (ON Semiconductor) | Same DO-204AC (DO-15) package and 180V rating; identical 600W rating; VC = 246V @ 2.5A; RoHS-compliant but not AEC-Q101 qualified. | Valid for industrial and commercial use; not certified for automotive under-hood deployment where AEC-Q101 is mandated. | Select 1.5KE180A for cost-sensitive industrial applications where automotive qualification is unnecessary. |
Compared with P6KE180A, SMBJ180A offers superior thermal dissipation in compact SMT layouts but requires redesign, while 1.5KE180A provides identical form-factor and clamping performance without AEC-Q101 validation - making P6KE180A the preferred choice for automotive-qualified, through-hole TVS protection.

FAQ
What is the polarity configuration of the P6KE180A?
The P6KE180A is a unidirectional TVS diode, with polarity indicated by a cathode band on the DO-204AC (DO-15) package. When installed, the banded end connects to the protected line (e.g., +12V rail), and the unbanded end connects to ground. This configuration allows it to clamp positive transients while blocking reverse conduction - a key distinction from bidirectional variants like P6KE180CA.
Does the P6KE180A meet AEC-Q101 qualification?
The base P6KE180A is not AEC-Q101 qualified; however, the P6KE180AH variant (with "H" suffix) is explicitly AEC-Q101 qualified per the manufacturer's ordering information. Engineers requiring automotive under-hood deployment must specify P6KE180AH - the "H" denotes qualification testing per stress conditions defined in AEC-Q101 Rev D.
What is the maximum clamping voltage of the P6KE180A under standard surge conditions?
The P6KE180A has a maximum clamping voltage (VC) of 246 V when subjected to a 10/1000μs surge waveform at a peak current (IPP) of 2.5 A. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage seen by downstream components during a full-rated 600W transient event.
Can the P6KE180A be used in bidirectional signal line protection?
No - the P6KE180A is unidirectional and unsuitable for bidirectional signal lines such as RS-485 or CAN. For symmetric transient suppression on AC or differential lines, the P6KE180CA (bidirectional variant) must be used instead. Using P6KE180A on bidirectional paths risks reverse conduction failure and inadequate negative-going transient suppression.
How does the P6KE180A compare to the 1.5KE180A in terms of electrical performance?
The P6KE180A and 1.5KE180A share identical key parameters: 180V nominal breakdown, 154V VWM, 246V VC @ 2.5A, and 600W PPK rating. Both use DO-204AC (DO-15) packaging. The primary difference lies in qualification - P6KE180A offers optional AEC-Q101 (via H-suffix), whereas 1.5KE180A does not carry that certification, limiting its use in automotive applications.
