Product details
Overview
P6KE160C from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 160V nominal standoff voltage, 230V maximum clamping voltage at 2.7A peak pulse current, 600W peak pulse power rating (10/1000μs), and DO-204AC (DO-15) axial package - deployed in automotive lighting control modules to protect CAN transceiver inputs from load-dump-induced transients.
For engineers reviewing the P6KE160C datasheet, P6KE160C pinout, P6KE160C application, or P6KE160C equivalent, key selection criteria include bidirectional clamping symmetry, low dynamic impedance under surge, AEC-Q101 qualification status, junction temperature derating above 25°C, and compatibility with 10/1000μs waveform immunity testing per IEC 61000-4-5.
Technical Context
The P6KE160C operates as a silicon avalanche diode with symmetrical bidirectional breakdown behavior - VBR min/max = 144V/176V measured at 1mA test current, enabling consistent clamping in both polarities. Its low dynamic impedance ensures rapid voltage limiting during fast-rising transients, while the 175°C maximum junction temperature supports operation in under-hood automotive environments.
It complies with ANSI/IEEE C62.35 for transient suppression parameters and meets UL 94V-0 flammability requirements in its DO-204AC molding compound. The device exhibits a temperature coefficient of VBR of 0.108%/°C, requiring thermal design consideration in high-ambient applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 130 V - Maximum continuous reverse working voltage before significant leakage; defines safe operating margin below clamping threshold |
| Breakdown Voltage (VBR) | 144–176 V at 1 mA - Avalanche onset range; determines minimum transient level that triggers clamping action |
| Clamping Voltage (VC) | 230 V at 2.7 A IPP - Peak voltage seen by protected circuit during 10/1000μs surge; critical for IC voltage tolerance margining |
| Peak Pulse Power (PPK) | 600 W - Energy-handling capability per single 10/1000μs transient; defines survivability against ISO 7637-2 Pulse 5a/b events |
| Junction Temperature (TJ) | −55°C to +175°C - Operating range enabling use in engine control units and powertrain electronics without derating loss |
| Leakage Current (ID) | <1 μA at 130 V - Minimal standby power loss and signal integrity impact in always-on systems |
| Response Time | <5 ns - Time from 0 V to VBR in bidirectional mode; ensures protection before sensitive logic thresholds are exceeded |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with cathode band marking for unidirectional variants; P6KE160C is bidirectional and marked without polarity band per datasheet specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction | No functional polarity - either terminal serves as anode or cathode depending on transient polarity; enables placement without orientation constraints |
| Lead 1 (Anode side) | Terminal connection | Tin-plated copper lead compliant with J-STD-002 solderability; supports wave and reflow assembly |
| Lead 2 (Cathode side) | Terminal connection | Identical mechanical/electrical spec to Lead 1; no functional distinction in bidirectional configuration |

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 (Bourns) | Same 160V VWM, 230V VC, but SMB package (surface-mount); 600W rating; lower thermal resistance (junction-to-ambient ≈ 50°C/W vs. DO-15's ≈ 70°C/W) | Preferred for space-constrained PCBs; requires reflow-compatible layout; not axial-lead drop-in replacement | Select SMBJ160CA when board real estate is limited and thermal management via copper pour is feasible. |
| 1.5KE160CA (ON Semiconductor) | Same DO-204AC package and 160V rating, but 1500W peak power (10/1000μs); higher IPP (12.3A); larger junction area; slightly higher VC (240V) | Used where higher single-event surge margin is required (e.g., alternator output lines); may require revised layout for thermal relief | Choose 1.5KE160CA only if system-level testing confirms need for >600W handling; otherwise P6KE160C offers optimal cost/performance balance. |
Compared with SMBJ160CA and 1.5KE160CA, the P6KE160C delivers identical clamping performance in a legacy axial package optimized for through-hole assembly and high-reliability automotive harness connections - making it ideal for serviceable modules and legacy production lines where footprint and mounting method are fixed.

FAQ
What is the polarity configuration of P6KE160C?
The P6KE160C is a bidirectional TVS diode with symmetrical avalanche characteristics - it has no designated anode or cathode and functions identically regardless of voltage polarity. Unlike unidirectional variants (e.g., P6KE160A), P6KE160C does not feature a cathode band marking and is intended for AC or reversible DC protection applications where polarity reversal is possible.
Is P6KE160C AEC-Q101 qualified?
Yes, P6KE160C is AEC-Q101 qualified per the manufacturer's ordering code suffix "C" and documentation in the P6KE series datasheet (Version P2203). This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD - confirming suitability for automotive powertrain and chassis applications.
What is the maximum clamping voltage of P6KE160C under surge conditions?
The maximum clamping voltage (VC) of P6KE160C is 230 V at a peak pulse current (IPP) of 2.7 A, tested with the standard 10/1000 μs double-exponential waveform. This value represents the highest voltage imposed on the protected circuit during a worst-case surge event and must be compared against the absolute maximum ratings of downstream components.
How does P6KE160C differ from P6KE160A?
P6KE160C is bidirectional with symmetrical clamping in both polarities, while P6KE160A is unidirectional and features a cathode band marking. Their electrical parameters differ slightly: P6KE160A has VBR = 152–168 V and VC = 219 V at 2.8 A, whereas P6KE160C specifies VBR = 144–176 V and VC = 230 V at 2.7 A - reflecting the inherent asymmetry tolerance in unidirectional designs versus tighter symmetry in bidirectional ones.
What package type does P6KE160C use and what are its mechanical dimensions?
P6KE160C uses the DO-204AC (DO-15) axial-leaded package, with overall dimensions of 4.3 mm diameter × 8.9 mm length and lead spacing of 5.0 mm. The leads are pure tin-plated for solderability per J-STD-002, and the epoxy body meets UL 94V-0 flammability rating - making it suitable for wave soldering and high-reliability through-hole assembly.
