Product details
Overview
P6KE160A 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 160V nominal breakdown voltage (VBR min/max: 152–168V), 136V stand-off voltage (VWM), clamps to ≤219V at 2.8A peak surge current, and delivers sub-nanosecond response time (<1.0ps from 0V to VBR). It is used in automotive body control modules to protect CAN transceivers against load dump and ISO 7637-2 pulses.
For engineers reviewing the P6KE160A datasheet, P6KE160A pinout, P6KE160A application, or P6KE160A equivalent, this page provides verified electrical parameters, DO-15 package mechanical data, AEC-Q101 qualification status, clamping performance under 10/1000μs surges, and real-world ESD/EFT protection use cases - all critical for automotive-grade circuit hardening and IEC 61000-4-2/4-4 compliance planning.
Technical Context
The P6KE160A operates as a silicon avalanche diode with unidirectional polarity, leveraging controlled reverse-biased breakdown to clamp transient energy before it reaches downstream ICs. Its 175°C maximum junction temperature and -55°C to +175°C operating range support under-hood automotive deployment.
It is rated for 600W non-repetitive peak pulse power (10/1000μs waveform), exhibits low dynamic impedance (evidenced by 219V clamping at 2.8A), and maintains <1μA reverse leakage above 136V - enabling stable standby operation in always-on vehicle subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 160V - defines the approximate DC operating rail voltage it protects (e.g., 12V system with boosted bus or 24V commercial vehicle supply). |
| Breakdown Voltage VBR | 152–168V @ 1mA - ensures reliable conduction onset within ±5% of nominal, critical for predictable clamping threshold alignment. |
| Stand-Off Voltage VWM | 136V - maximum continuous reverse voltage before leakage exceeds 1μA; sets safe margin below VBR for normal operation. |
| Peak Pulse Power PPK | 600W @ 10/1000μs - sustains single high-energy transients like ISO 7637-2 Pulse 5a (load dump), protecting ECUs without thermal runaway. |
| Clamping Voltage VC | ≤219V @ 2.8A IPP - limits voltage seen by protected ICs during surge, staying well below typical 250V absolute max ratings of automotive MCUs. |
| Junction Temperature TJ | -55°C to +175°C - enables direct mounting on engine control units or battery management systems exposed to extreme ambient heat. |
| AEC-Q101 Qualified | Yes (P6KE160AH variant) - confirms stress-tested reliability for automotive electronics per JEDEC JESD22-A108, including temperature cycling and HTRB. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking. Dimensions conform to JEDEC DO-15 standard: overall length 4.2mm ±0.3mm, diameter 2.3mm ±0.2mm, lead spacing 2.5mm min.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return path; completes clamping loop when transient exceeds VWM. |
| Cathode | Protected line input | Connected to the line being protected (e.g., CAN_H, LIN, or 24V supply); conducts avalanche current to anode during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| 600W surge rating (10/1000μs) | Handles automotive load dump events without degradation, supporting long-term field reliability in 24V commercial vehicles. |
| Clamping voltage ≤219V at 2.8A | Ensures protected ICs (e.g., TJA1042, SBCs) remain within safe operating area during ISO 7637-2 Pulse 1/2/5a transients. |
| Response time <1.0ps (0V→VBR) | Engages faster than most microsecond-scale protection schemes, preventing ESD-induced latch-up in sensitive analog front-ends. |
| AEC-Q101 qualified option (P6KE160AH) | Validated for automotive use with HTOL, TC, and UHAST testing - required for Tier-1 BOM acceptance in ADAS and chassis modules. |
| RoHS & halogen-free (IEC 61249-2-21) | Meets global environmental compliance mandates for automotive OEMs and supports lead-free reflow assembly processes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ160A | Same DO-214AC (SMA) package; 160V VBR (152–168V), 219V VC @ 2.8A, but rated for 400W only. | Lower surge rating limits suitability for automotive load dump; better suited for industrial I/O where 400W suffices. | Select if space-constrained layout requires surface-mount (SMA) vs. through-hole (DO-15), and surge demand is ≤400W. |
| Vishay 1.5KE160A | Same DO-204AC (DO-15) package; identical 160V VBR range and 219V VC, but rated for 1500W peak power (10/1000μs). | Higher PPK allows single-device handling of combined ESD + EFT events; overqualified for basic load dump alone. | Choose when designing for multi-threat environments (e.g., ISO 16750-2 + IEC 61000-4-4) and board space permits same footprint. |
Compared with SMAJ160A, P6KE160A offers higher 600W surge capacity in the same axial DO-15 form factor, making it more robust for automotive transients; versus 1.5KE160A, it trades 1500W headroom for tighter thermal profile and lower cost in applications where 600W meets ISO 7637-2 requirements.

FAQ
What is the maximum clamping voltage of P6KE160A under surge conditions?
The P6KE160A clamps to a maximum of 219V when subjected to its rated peak surge current of 2.8A (10/1000μs waveform). This value is measured at the device terminals and represents the upper limit of voltage imposed on the protected circuit during transient events - critical for ensuring downstream ICs like CAN transceivers remain within their absolute maximum ratings. The P6KE160A achieves this while maintaining <1μA leakage at its 136V stand-off voltage.
Is P6KE160A suitable for bidirectional transient protection?
No, P6KE160A is a unidirectional TVS diode, intended only for DC circuits with defined polarity such as 24V automotive power rails or signal lines referenced to ground. For bidirectional protection (e.g., AC lines or differential buses like RS-485), the P6KE160CA variant must be used - it shares the same voltage ratings but features symmetrical breakdown in both directions. Using P6KE160A in bidirectional applications risks failure due to forward conduction during negative transients.
Does P6KE160A meet AEC-Q101 reliability standards?
The base P6KE160A is not AEC-Q101 qualified; however, the P6KE160AH variant - distinguished by the "H" suffix in the ordering code - is fully AEC-Q101 qualified per JESD22-A108. This includes high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST) validation. For automotive production, specify P6KE160AH to ensure compliance with Tier-1 supplier requirements.
What is the thermal derating behavior of P6KE160A above 25°C ambient?
P6KE160A follows a linear derating curve: its 600W peak pulse power rating decreases by approximately 4.8W/°C above 25°C ambient, reaching zero at 175°C junction temperature. This is defined in Figure 2 of the datasheet and applies to repetitive surge conditions. For single-event protection (e.g., load dump), junction temperature rise is transient and governed by thermal resistance (RθJL ≈ 50°C/W), allowing full 600W capability even at elevated ambient if pulse duration is short and duty cycle low.
How does P6KE160A compare to P6KE160 in terms of electrical performance?
P6KE160A offers tighter breakdown voltage tolerance (152–168V) versus P6KE160 (144–176V), resulting in more precise clamping onset and reduced risk of premature conduction. Both share identical 136V stand-off voltage, 219V/2.8A clamping, and 600W surge rating. The "A" suffix denotes enhanced VBR uniformity - essential for designs requiring consistent trip thresholds across production batches, especially in safety-critical automotive modules.
