Product details
Overview
P6KE170CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 170 V breakdown voltage (min 162 V, max 179 V at 1 mA), 145 V standoff voltage, and clamps to ≤234 V at 2.6 A peak pulse current. Used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE170CA-E3/54 datasheet, P6KE170CA-E3/54 pinout, P6KE170CA-E3/54 application, or P6KE170CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), and compliance with UL 497B for telecom and industrial protectors.
Technical Context
This device operates as a voltage-clamped shunt protector: during transient overvoltage events exceeding its standoff voltage (VWM = 145 V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns).
Designed for unidirectional and bidirectional configurations, the P6KE170CA-E3/54 variant uses the "CA" suffix to denote symmetrical bidirectional operation - electrical characteristics apply identically in both polarities. It supports repetitive surges at 0.01 % duty cycle and withstands soldering up to 275 °C for 10 s per JESD 22-B106.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 162 V / 179 V at 1 mA - defines guaranteed avalanche initiation range under DC test conditions |
| VWM | 145 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| VC @ IPPM | ≤234 V at 2.6 A - clamping voltage during 10/1000 μs surge, limiting stress on protected ICs |
| PPPM | 600 W - peak pulse power handling capacity, critical for IEC 61000-4-5 Level 4 compliance |
| RθJL | 20 °C/W - junction-to-lead thermal resistance enables reliable power dissipation without heatsink |
| TJ max | +175 °C - extended junction temperature rating supports under-hood automotive use |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling and HTRB |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient current path terminal | Both ends function identically; connects across protected line and ground or between differential lines |
| Lead 1 / Lead 2 | Thermal and electrical interface | Provides mechanical mounting and primary heat conduction path to PCB copper; RθJL = 20 °C/W measured between either lead and junction |
Key Features

Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Shunt TVS placed between signal line and chassis ground to clamp transients before they reach sensitive input pins of transceivers or ADC front-ends. Use Value: Prevents latch-up or permanent damage to automotive-grade ICs by limiting transient voltage to ≤234 V while sustaining 600 W surge energy. | Use Scenario: Safeguarding RS-485/RS-232 communication ports on PLCs and motor drives exposed to field wiring surges. IC Role / Device Role / Timing Role: Bidirectional clamping element across differential pair (A/B) or single-ended line-to-ground, absorbing common-mode and differential-mode transients. Use Value: Enables compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) immunity requirements without adding active circuitry. |
| Telecom Line Protection | Consumer Power Adapter Input |
Use Scenario: Shielding Ethernet PHY interfaces and DSL line drivers from induced surges on outdoor cabling in telecom infrastructure equipment. IC Role / Device Role / Timing Role: Primary-level protector mounted at connector entry point, working in coordination with GDT or MOV secondary stages. Use Value: UL 497B recognition allows direct integration into certified telecom protectors without requalification of full assembly. | Use Scenario: Suppressing line-side surges entering AC-DC adapters used in smart home devices and audio equipment. IC Role / Device Role / Timing Role: Secondary-stage TVS after fuse and MOV, providing precise clamping to protect bridge rectifier and primary-side controller ICs. Use Value: 145 V standoff voltage matches typical 120 VAC RMS × √2 ≈ 170 V peak, allowing normal operation while blocking surge overvoltage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ170CA | Same VBR range (162–179 V), but SMC (DO-214AB) surface-mount package; 600 W rating retained | Requires PCB redesign for SMT layout; better thermal performance (RθJA ≈ 40 °C/W vs. 75 °C/W for DO-15) | Select when board space is constrained and automated assembly is preferred over through-hole mounting. |
| 1.5KE170CA | Same DO-15 package and VBR, but higher 1500 W peak pulse power (10/1000 μs); larger die size increases capacitance | Higher clamping voltage (≤258 V) and greater junction capacitance limit use in high-speed data lines | Choose for higher-energy surge environments where footprint compatibility is mandatory and speed is not critical. |
Compared with SMBJ170CA and 1.5KE170CA, the P6KE170CA-E3/54 offers optimal balance of cost, through-hole manufacturability, and standardized surge immunity for mid-tier industrial and automotive applications - especially where legacy DO-15 footprints and AEC-Q101 validation are required.

FAQ
What does the "CA" suffix mean in P6KE170CA-E3/54?
The "CA" suffix in P6KE170CA-E3/54 indicates a bidirectional configuration: the device provides symmetrical transient suppression in both polarities, with identical breakdown and clamping characteristics regardless of voltage polarity applied. This makes it suitable for AC-coupled lines, differential buses like CAN or RS-485, and any application where polarity reversal or common-mode surges may occur. Unidirectional variants (e.g., P6KE170A) include a cathode band and conduct only in reverse bias.
Is P6KE170CA-E3/54 qualified for automotive use?
Yes, P6KE170CA-E3/54 is AEC-Q101 qualified - confirmed in Vishay's official documentation (Document Number: 88369, Revision: 27-Sep-2021). This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (uHAST), validating its suitability for under-hood and body-control module applications. The "HE3" variant is explicitly marked for AEC-Q101; however, the E3/54 part shares the same die and qualification data per Vishay's ordering information note.
What is the maximum clamping voltage of P6KE170CA-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE170CA-E3/54 is 234 V, measured at its rated peak pulse current (IPPM) of 2.6 A using a 10/1000 μs waveform. This value represents the upper limit of voltage seen by downstream circuitry during worst-case surge events and is critical for ensuring protected ICs remain within their absolute maximum ratings. Clamping voltage increases with higher surge current and decreases with lower duty cycles or shorter pulse widths.
Can P6KE170CA-E3/54 be used in place of P6KE170A?
No - P6KE170CA-E3/54 and P6KE170A are not interchangeable without circuit review. While both share identical breakdown (162–179 V) and standoff (145 V) voltages, P6KE170A is unidirectional (cathode-marked, conducts only in reverse bias), whereas P6KE170CA-E3/54 is bidirectional (no polarity marking, symmetrical conduction). Substituting one for the other may cause unintended conduction or failure to suppress positive-going transients in unidirectional designs.
What packaging format is supplied for P6KE170CA-E3/54?
P6KE170CA-E3/54 is supplied in 13-inch diameter paper tape and reel packaging, with a base quantity of 4000 units per reel (ordering code "/54"). The "E3" suffix confirms RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability requirements and JESD 201 Class 1A whisker resistance. Tape-and-reel format supports automated through-hole insertion equipment compatible with DO-15 lead spacing.
