Product details
Overview
P6KE170C 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 170V nominal breakdown voltage (VBR min/max = 153V/187V), 600W peak pulse power rating at 10/1000μs, clamping voltage of 244V at 2.5A peak surge current, and low dynamic impedance for effective overvoltage clamping in automotive and industrial control systems.
For engineers reviewing the P6KE170C datasheet, P6KE170C pinout, P6KE170C application, or P6KE170C equivalent, this device is evaluated for ESD and electrical fast transient (EFT) immunity in 12–48V DC systems, unidirectional/bidirectional surge suppression per IEC 61000-4-2/4-4, and AEC-Q101-compliant deployment where polarity-insensitive clamping is required.
Technical Context
The P6KE170C operates as a silicon avalanche diode with symmetrical bidirectional clamping behavior - both anodes tied internally to form a center-tapped structure enabling identical VBR and VC characteristics in either polarity. Its junction capacitance is not specified in the provided documentation, but its fast response time (<5.0ns for bidirectional mode) ensures sub-microsecond conduction onset during transients.
Thermal derating follows a linear curve above 25°C ambient, with full 600W capability only at TA ≤ 25°C and zero-rated power at 175°C junction temperature. The device uses a single-die DO-204AC (DO-15) package with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 170V - defines mid-point of breakdown range; used for system-level voltage margining against surges |
| Breakdown Voltage VBR | 153V to 187V at 1mA test current - guarantees clamping activation within ±10% tolerance band |
| Stand-off Voltage VWM | 138V - maximum continuous reverse voltage before leakage exceeds 1μA; sets safe operating DC bias limit |
| Peak Pulse Power PPK | 600W at 10/1000μs waveform - supports single-event surge energy up to 600W × 1ms = 0.6J |
| Clamping Voltage VC | 244V at 2.5A IPP - limits downstream voltage stress during worst-case surge; critical for IC input protection |
| Junction Temperature Range | −55°C to +175°C - enables operation in under-hood automotive and industrial environments |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.400g mass and UL 94V-0 molding compound |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking for unidirectional variants; P6KE170C is bidirectional and marked without polarity indicator. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance. Weight: 0.400g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 / Cathode 1 | Bidirectional terminal A | Either terminal serves as anode or cathode depending on transient polarity; no fixed polarity |
| Anode 2 / Cathode 2 | Bidirectional terminal B | Completes symmetrical clamping path; terminals interchangeable in PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping symmetry | Identical VBR (153–187V) and VC (244V) in both directions - eliminates need for polarity-aware placement |
| AEC-Q101 qualification | Qualified version available (P6KE170CH) - meets stress testing requirements for automotive electronics |
| Low clamping ratio | VC/VBR(max) = 244/187 ≈ 1.30 - tight voltage limiting reduces risk of downstream component overstress |
| Fast transient response | <5.0ns turn-on time for bidirectional mode - captures nanosecond-scale ESD events before propagation |
| UL recognition | UL File #E-326243 - validates safety compliance for end-equipment certification (e.g., UL 62368) |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |

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 SMAJ170CA | Same DO-214AC (SMA) package; 600W rating; VBR = 153–171V; VC = 274V @ 2.2A | Higher clamping voltage (+30V) and surface-mount format - requires PCB redesign | Select when SMT assembly is mandatory and higher VC is acceptable for downstream voltage margins |
| Vishay 1.5KE170CA | Same DO-201AD package; 1500W rating; VBR = 153–187V; VC = 274V @ 5.5A | Higher power handling but larger footprint and 30V higher clamping - less precise voltage limiting | Select when legacy 1.5kW surge immunity is required and board space allows DO-201AD mounting |
Compared with P6KE170C, SMAJ170CA trades axial-leaded ease-of-rework and lower clamping for SMT compatibility, while 1.5KE170CA offers higher surge capacity at the cost of less stringent voltage control and larger package size - P6KE170C balances precision clamping, AEC-Q101 readiness, and through-hole serviceability.

FAQ
What is the polarity configuration of P6KE170C?
P6KE170C is a bidirectional TVS diode with symmetrical clamping characteristics in both polarities. Unlike unidirectional variants (e.g., P6KE170A), it has no cathode band marking and functions identically regardless of voltage polarity applied across its terminals - making it ideal for AC-coupled or polarity-agnostic DC protection.
Does P6KE170C meet AEC-Q101 qualification?
The base P6KE170C is not AEC-Q101 qualified; however, the variant P6KE170CH (with "H" suffix) is explicitly listed in the ordering table as AEC-Q101 qualified. This qualification covers temperature cycling, humidity testing, and mechanical shock per AEC-Q101 Rev D, confirming suitability for automotive under-hood applications.
What is the maximum clamping voltage of P6KE170C and at what current is it specified?
The maximum clamping voltage (VC) of P6KE170C is 244V, measured at a peak pulse current (IPP) of 2.5A using the 10/1000μs standard waveform. This value represents the upper bound of voltage seen by protected circuitry during a defined surge event and is guaranteed across the full operating temperature range.
How does P6KE170C compare to P6KE170A in terms of electrical performance?
P6KE170A is the unidirectional version with a cathode band marking and tighter VBR tolerance (162–179V vs. 153–187V for P6KE170C). Its clamping voltage is lower at 234V @ 2.6A, but it cannot suppress positive-going transients on the cathode side. P6KE170C provides polarity-insensitive protection at the expense of slightly higher VC and wider VBR spread.
What packaging options are available for P6KE170C?
P6KE170C is supplied in DO-204AC (DO-15) package with two standard packing formats: 3,500 units per tape-and-reel (P6KE170CH for AEC-Q101 version) and 1,500 units per ammo box (P6KE170CA0G). Lead finish is pure tin, compliant with J-STD-002 for solderability and RoHS/IEC 61249-2-21 for halogen-free construction.
