Product details
Overview
P6KE160CAH from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in automotive and industrial power rails. It features a standoff voltage of 130 V, breakdown voltage range of 144–176 V at 1 mA test current, clamping voltage of 230 V at 2.7 A peak pulse current, and operates across –55°C to +175°C junction temperature. It is used to protect CAN transceivers, power supply inputs, and microcontroller I/O against EFT and lightning-induced surges.
For engineers reviewing the P6KE160CAH datasheet, P6KE160CAH pinout, P6KE160CAH application, or P6KE160CAH equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package compatibility, bidirectional clamping symmetry, low leakage (<1 µA at 130 V), and 10/1000 µs waveform surge rating - all critical for automotive-grade ESD/EFT immunity design.
Technical Context
The P6KE160CAH implements a silicon avalanche diode structure optimized for fast transient response (<5 ns rise time for bidirectional operation) and stable clamping under repetitive surge stress. Its unidirectional counterpart uses cathode band marking; the "CA" suffix confirms symmetrical bidirectional behavior with identical VBR min/max in both polarities.
Thermal derating follows a linear curve above 25°C ambient, maintaining 600 W peak pulse power only at TA ≤ 25°C and reducing to ~300 W at 75°C. The device's 0.108 %/°C VBR temperature coefficient ensures predictable voltage drift over temperature, supporting robust overvoltage threshold design in wide-temperature environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 600 W - sustains single high-energy surges per IEC 61000-4-5 Level 4 without failure |
| Standoff Voltage (VWM) | 130 V - maximum continuous reverse operating voltage before significant leakage |
| Breakdown Voltage (VBR) | 144–176 V @ 1 mA - defines the onset of avalanche conduction in either polarity |
| Clamping Voltage (VC) | 230 V @ 2.7 A IPP - limits downstream voltage during surge, protecting 200 V-rated components |
| Junction Temperature Range | –55°C to +175°C - supports under-hood automotive and industrial power-conversion applications |
| Leakage Current (ID) | <1 µA @ 130 V - minimizes standby power loss and avoids false triggering in high-impedance circuits |
| Response Time | <5 ns - enables suppression of fast transients such as EFT bursts (IEC 61000-4-4) |

Use Scenario: Protecting ISO 11898-2 compliant CAN transceivers from load dump, jump-start, and EFT pulses on vehicle wiring harnesses. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across CAN_H/CAN_L differential pair or between each line and chassis ground. Use Value: Clamps transients to ≤230 V while maintaining <1 µA leakage at 130 V system voltage - preserving bus signal integrity and preventing transceiver latch-up. |
Use Scenario: Safeguarding 12–48 V DC power inputs in PLC modules, motor drives, and sensor nodes against lightning-induced surges and inductive switching spikes. IC Role / Device Role / Timing Role: Primary surge suppression device mounted at board edge, upstream of input filter and DC-DC converter. Use Value: Absorbs 600 W (10/1000 µs) without degradation, enabling compliance with IEC 61000-4-5 Level 4 (4 kV line-to-ground) testing. |
| LED Driver Overvoltage Protection | Smart Meter EFT Immunity |
|
Use Scenario: Preventing catastrophic failure of constant-current LED drivers exposed to utility grid transients during outdoor lighting installations. IC Role / Device Role / Timing Role: Parallel-connected TVS across driver output terminals or input bulk capacitor. Use Value: Fast <5 ns response captures nanosecond-scale spikes; 230 V clamping protects 200 V-rated MOSFETs and ICs downstream of the driver stage. |
Use Scenario: Enhancing immunity of revenue-grade smart meters to electrical fast transients (IEC 61000-4-4) on AC mains and communication ports. IC Role / Device Role / Timing Role: Secondary protection layer after MOVs, placed directly at microcontroller GPIO or RS-485 transceiver pins. Use Value: Sub-1 µA leakage at 130 V prevents meter calibration drift; bidirectional symmetry eliminates orientation errors during automated assembly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Same VWM (130 V), lower PPP (600 W → 600 W), but SMB package (smaller footprint, higher thermal resistance) | Preferred for space-constrained PCBs; requires thermal pad design for >100°C ambient | Select when board area is limited and thermal management via copper pour is feasible |
| 1.5KE160CA | Same VWM/VBR/VC specs, but higher PPP (1500 W), larger DO-201AD package, slower response (~10 ns) | Suitable for legacy systems requiring higher surge margin; not AEC-Q101 qualified | Choose for non-automotive industrial applications needing greater single-pulse energy handling |
Compared with SMBJ160CA and 1.5KE160CA, the P6KE160CAH delivers AEC-Q101 validation and DO-15 mechanical robustness ideal for automotive harness interfaces, while balancing surge capacity, leakage, and thermal performance without requiring layout redesign.

FAQ
What does the "CA" suffix mean in P6KE160CAH?
The "CA" suffix in P6KE160CAH denotes bidirectional configuration - meaning the device provides symmetrical avalanche clamping in both forward and reverse directions, with identical breakdown voltage (144–176 V) and clamping voltage (230 V) characteristics regardless of polarity. This eliminates orientation dependency during PCB assembly and simplifies protection of differential lines like CAN or RS-485.
Is P6KE160CAH suitable for 24 V automotive power rail protection?
Yes, P6KE160CAH is appropriate for 24 V system protection when used as secondary or tertiary suppression - its 130 V standoff voltage ensures no conduction during normal operation or load dump (up to ~40 V), while its 230 V clamping voltage safeguards downstream 200 V-rated components. It is commonly deployed alongside primary MOVs or polymer PTCs in multi-stage automotive power protection networks.
How does the AEC-Q101 qualification impact P6KE160CAH's use in automotive designs?
The AEC-Q101 qualification of P6KE160CAH validates its reliability under automotive stress conditions including temperature cycling (–55°C to +150°C), high-temperature reverse bias (1000 hrs at 150°C), and mechanical shock. This certification allows direct use in engine control units, body control modules, and ADAS sensors without additional qualification testing - accelerating time-to-market for Tier 1 suppliers.
What is the maximum peak pulse current (IPP) rating for P6KE160CAH?
The maximum peak pulse current (IPP) for P6KE160CAH is 2.7 A under the standard 10/1000 µs double-exponential waveform. This value corresponds to its 600 W peak pulse power rating at the specified clamping voltage of 230 V. Derating applies above 25°C ambient per Figure 2 in the datasheet, reducing IPP to approximately 1.9 A at 75°C.
Can P6KE160CAH replace P6KE160A in an existing design?
No - P6KE160CAH and P6KE160A are not interchangeable. P6KE160A is unidirectional (cathode-banded), while P6KE160CAH is bidirectional (no polarity marking). Substituting one for the other risks incorrect clamping behavior: P6KE160A would fail to protect reverse-polarity transients, and P6KE160CAH may conduct prematurely in DC-coupled unidirectional paths. Always verify circuit topology before replacement.
