Product details
Overview
P6KE160CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 160V nominal breakdown voltage (VBR min/max: 144V–176V), 130V standoff voltage (VWM), clamps to ≤230V at 2.7A 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 body electronics and industrial power supply inputs.
For engineers reviewing the P6KE160CH datasheet, P6KE160CH pinout, P6KE160CH application, or P6KE160CH equivalent, key selection criteria include its 130V working voltage, 230V clamping limit at 2.7A, AEC-Q101 qualification, DO-15 mechanical compatibility, and suitability for 12/24V system EFT/ESD protection per IEC 61000-4-4/4-2.
Technical Context
The P6KE160CH operates as a unidirectional avalanche diode with silicon planar junction construction, optimized for fast clamping of high-energy transients such as load dump, inductive switching spikes, and EFT bursts. Its low dynamic impedance ensures minimal voltage overshoot during 10/1000μs surges up to 600W, while its <1.0ps response enables protection of sensitive downstream ICs like microcontrollers and CAN transceivers.
Thermal performance is defined by a 175°C maximum junction temperature and derating above 25°C ambient per Fig.2; steady-state power dissipation is rated at 5W at 75°C with 9.5mm lead length. The device meets UL 94V-0 flammability, JESD201 Class 2 whisker resistance, and RoHS/halogen-free compliance per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; sets safe DC rail margin for 12/24V systems. |
| VBR (min/max) | 144 V / 176 V - Breakdown occurs within this range at 1 mA test current; defines threshold for reliable transient clamping activation. |
| VC @ IPP | 230 V @ 2.7 A - Clamped voltage during 10/1000μs surge; determines maximum stress imposed on protected circuitry. |
| PPK | 600 W - Peak pulse power handling capability; supports robust immunity against ISO 7637-2 load dump and IEC 61000-4-5 surges. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ160A | Same 160V nominal, DO-214AC (SMA) surface-mount package; 224V clamping at 2.7A; slightly lower PPK (400W). | Requires PCB redesign for SMT placement; better suited for space-constrained telecom modules than through-hole automotive harnesses. | Select when board area is limited and reflow assembly is available; verify thermal pad layout for 175°C operation. |
| ON Semiconductor 1.5KE160A | Same DO-204AC (DO-15) package and 160V rating; 230V clamping at 2.7A; identical 600W rating but not AEC-Q101 qualified. | Lacks automotive qualification; acceptable for industrial controls but not for OEM automotive Tier-1 BOMs requiring AEC validation. | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated; confirm lifecycle availability separately. |
Compared with SMAJ160A and 1.5KE160A, the P6KE160CH uniquely combines AEC-Q101 qualification, DO-15 through-hole compatibility, and 600W surge capability-making it the only drop-in solution for automotive production programs requiring validated reliability and legacy assembly support.

FAQ
What is the clamping voltage of P6KE160CH at its rated surge current?
The P6KE160CH clamps to a maximum of 230 V when subjected to its peak pulse current of 2.7 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during transient events-critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P6KE160CH suitable for bidirectional transient protection?
No, P6KE160CH is a unidirectional TVS diode, indicated by the "H" suffix and absence of "C" or "CA" designation. It protects only against reverse-polarity transients on positive rails. For bidirectional protection (e.g., data lines), use P6KE160CH's counterpart P6KE160A or P6KE160CA, which exhibit symmetrical breakdown in both directions.
Does P6KE160CH meet automotive qualification standards?
Yes, P6KE160CH is explicitly AEC-Q101 qualified per the manufacturer's ordering code definition ("H" suffix denotes AEC-Q101 qualification for P6KE series excluding low-voltage variants). This includes stress testing for temperature cycling, humidity bias, mechanical shock, and accelerated life validation-required for inclusion in automotive electronic control units.
What is the maximum operating temperature for P6KE160CH?
The P6KE160CH has a maximum junction temperature (TJ) of 175°C and a storage temperature range of –55°C to +175°C. Its thermal derating curve (Fig.2) specifies linear power reduction above 25°C ambient, allowing full 600W surge capability only at room temperature but maintaining functional clamping up to 175°C junction temperature.
How does the DO-204AC (DO-15) package of P6KE160CH affect PCB layout?
The DO-204AC (DO-15) package of P6KE160CH requires axial through-hole mounting with 0.400g mass and standard lead spacing. Layout must accommodate ≥2.54 mm pad-to-pad clearance, 9.5 mm lead length for 5W steady-state dissipation, and avoid thermal vias that compromise mechanical retention-unlike SMT alternatives, it supports manual rework and high-vibration environments without solder joint fatigue.
