Product details
Overview
P6KE160AH 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: 144V–176V), 136V standoff 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 AEC-Q101 qualified and housed in a DO-204AC (DO-15) package for automotive front-end power supply protection.
For engineers reviewing the P6KE160AH datasheet, P6KE160AH pinout, P6KE160AH application, or P6KE160AH equivalent, this device is selected for high-reliability transient suppression where precise clamping voltage, low leakage (<1μA @ 136V), and AEC-Q101 qualification are required - especially in 12V/24V/48V automotive subsystems, industrial PLC I/O protection, and LED driver input stages.
Technical Context
The P6KE160AH operates as a unidirectional avalanche diode with a single-die DO-204AC structure, optimized for 10/1000μs waveform surge immunity per IEC 61000-4-5. Its junction temperature range spans −55°C to +175°C, and it maintains stable VBR with a temperature coefficient of 0.108%/°C.
It exhibits low dynamic impedance and fast turn-on behavior, enabling effective clamping of ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and inductive switching transients. The device is rated for 100A non-repetitive forward surge (IFSM) and supports steady-state dissipation of 5W at 75°C with specified PCB pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin for 120–144V systems. |
| VBR (min/max) | 144 V / 176 V - Measured at 1 mA IT; ensures predictable avalanche initiation across temperature and lot variation. |
| VC @ IPP | 219 V @ 2.8 A - Clamping voltage during 10/1000μs surge; limits downstream IC stress to <220V under worst-case 600W transient. |
| PPK | 600 W - Peak pulse power rating at 10/1000μs; validates robustness against automotive load dump and ISO 7637-2 Pulse 5a/b. |
| IR @ VWM | <1 μA - Reverse leakage at rated standoff; minimizes standby power loss and avoids false triggering in high-impedance sensing circuits. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in under-hood automotive environments and sealed industrial enclosures. |
| Package | DO-204AC (DO-15) - Industry-standard axial-leaded package with tin-plated leads; compatible with wave and reflow soldering per J-STD-002. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking. Leads are pure tin-plated, compliant with JESD201 Class 2 whisker resistance and UL 94V-0 flammability rating. Weight: ~0.400 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to system ground or low-side return path; conducts during positive surge events on cathode side. |
| Cathode | Avalanche clamping terminal | Connected to protected line (e.g., battery rail); initiates breakdown when voltage exceeds VBR, shunting surge to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock - required for engine control, ADAS, and body electronics. |
| 600W 10/1000μs surge rating | Withstands ISO 7637-2 Pulse 5a (load dump) up to 120V superimposed on 24V systems without degradation. |
| Clamping voltage ≤219V | Ensures protected downstream components (e.g., LDOs, microcontrollers) remain below absolute maximum ratings during transients. |
| Response time <1.0ps | Activates before most semiconductor damage mechanisms initiate - critical for safeguarding high-speed CAN/LIN transceivers and sensor interfaces. |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU - supports green manufacturing and end-of-life recycling requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Same 160V VBR range but SMB package (surface-mount); lower PPK (600W same), higher IR (5μA @ VWM). | Preferred for space-constrained PCBs; lacks AEC-Q101 qualification and axial lead mechanical robustness. | Select SMBJ160A only when board real estate is limited and automotive qualification is not required. |
| 1.5KE160A | Same DO-204AC package and AEC-Q101 option available; higher PPK (1500W), wider VBR tolerance (144–176V → 144–187V), slower response (~1ns). | Used where higher energy absorption is needed (e.g., heavy-duty industrial motor drives); less precise clamping. | Choose 1.5KE160A if system-level surge testing requires >600W margin, accepting looser clamping control and larger footprint. |
Compared with SMBJ160A and 1.5KE160A, the P6KE160AH uniquely balances AEC-Q101 compliance, axial-leaded mechanical reliability, tight 144–176V VBR window, and sub-ps response - making it optimal for cost-sensitive yet safety-critical automotive and industrial power rail protection where leaded mounting and qualification are mandatory.

FAQ
What is the polarity configuration of the P6KE160AH?
The P6KE160AH is a unidirectional TVS diode with cathode-band marking indicating the clamping terminal. When installed, the cathode connects to the protected line (e.g., battery rail), and the anode connects to ground. This configuration allows it to clamp only positive-going transients while blocking reverse voltage - essential for DC power rail protection where negative excursions are not expected.
Does the P6KE160AH meet AEC-Q101 requirements?
Yes, the "H" suffix in P6KE160AH explicitly denotes AEC-Q101 qualification per the manufacturer's ordering code definition. It has undergone stress testing including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock - validating suitability for automotive powertrain, chassis, and body electronics applications per Rev D of the AEC-Q101 standard.
What is the maximum clamping voltage of the P6KE160AH under surge conditions?
The P6KE160AH clamps to a maximum of 219 V when subjected to its rated peak pulse current of 2.8 A (10/1000μs waveform). This value is guaranteed across temperature and process variation and is measured at the device terminals - critical for verifying that downstream components remain within their absolute maximum voltage ratings during transient events.
Can the P6KE160AH be used in bidirectional configurations?
No - the P6KE160AH is strictly unidirectional. For bidirectional protection, TSC offers the P6KE160CA variant (with "CA" suffix), which uses two back-to-back diodes in the same DO-204AC package. Using P6KE160AH in reverse-biased mode risks permanent breakdown due to lack of symmetric avalanche design and undefined reverse conduction characteristics.
What PCB layout considerations apply to the P6KE160AH?
For reliable 600W surge handling, the P6KE160AH must be mounted with 5 × 5 mm copper pads on each lead per datasheet thermal derating guidelines. Short, low-inductance traces to ground are essential to minimize voltage overshoot during fast transients. Avoid routing sensitive signals near its leads, and ensure cathode-side trace width accommodates peak surge current without fusing.
