Product details
Overview
P6KE170CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 145V reverse standoff voltage (VRWM), 162V minimum breakdown voltage (VBR), 234V maximum clamping voltage (VC) at 2.6A peak pulse current (IPP), and DO-15 package with glass-passivated junction-used in industrial power supplies and automotive body control modules.
For engineers reviewing the P6KE170CA-T datasheet, P6KE170CA-T pinout, P6KE170CA-T application, or P6KE170CA-T equivalent, key selection criteria include clamping voltage margin relative to system rail, unidirectional vs. bidirectional polarity requirements, 1.0ms pulse waveform compliance, thermal derating above +25°C ambient, and RoHS-compliant lead finish for automated assembly.
Technical Context
This bidirectional TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1MΩ at VRWM), but triggers into low-impedance conduction when transient voltage exceeds VBR, diverting surge current away from downstream circuitry. Its glass-passivated die ensures stable leakage and repeatable breakdown behavior across temperature.
The device complies with IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT) immunity standards when applied with appropriate PCB layout-its 234V clamping voltage limits protected ICs to safe stress levels during 8/20μs surges up to 2.6A, while its 600W peak pulse rating supports single-event transients without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (1.0ms 10/1000μs waveform; defines maximum single-event energy absorption capability) |
| Reverse Standoff Voltage (VRWM) | 145V (maximum continuous DC or RMS voltage before significant leakage; sets operating rail ceiling) |
| Breakdown Voltage (VBR) | 162V min @ 1mA (voltage at which device begins avalanche conduction; ensures reliable triggering above VRWM) |
| Clamping Voltage (VC) | 234V max @ 2.6A IPP (voltage seen by protected circuit during surge; determines stress on downstream components) |
| Package | DO-15 (axial-leaded, through-hole; enables manual or wave soldering; 0.4g mass; UL 94V-0 rated) |
| Operating Temperature | –55°C to +175°C (supports under-hood automotive and industrial environments without derating loss) |
| RoHS Compliance | Lead-free, halogen-free, antimony-free (meets EU Directive 2011/65/EU; suitable for green manufacturing) |
Pinout & Package
Package: DO-15 axial-leaded plastic package with molded UL 94V-0 housing, 9.5mm lead length, and cathode band marking omitted for bidirectional configuration (P6KE170CA-T has no polarity marking).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (reversible) | Bidirectional avalanche junction | Either terminal serves as anode or cathode depending on transient polarity; symmetrical clamping in both directions |
| Leads (anode & cathode) | Surge current path to PCB ground plane | Must be routed to low-inductance ground via short, wide traces; leads provide mechanical anchoring and thermal conduction to board copper |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power dissipation | Enables robust protection against IEC 61000-4-5 line surges up to 4kV (2Ω source impedance) without failure |
| Glass-passivated silicon die | Ensures stable VBR tolerance (±5%), low leakage (<5μA @ VRWM), and long-term reliability under thermal cycling |
| Bidirectional configuration | Protects AC-coupled or floating signal lines (e.g., RS-485, CAN bus, sensor bridges) without polarity constraints |
| Fast response time (<1ps) | Clamps transients before sensitive logic or analog circuitry experiences damaging overvoltage |
Applications
| Industrial Power Input Protection | Automotive Body Control Module |
|---|---|
Use Scenario: 24V DC input stage of programmable logic controller (PLC) exposed to load dump and inductive switching events. IC Role / Device Role / Timing Role: Primary shunt TVS placed upstream of input filter capacitor and DC-DC converter. Use Value: Clamps 120V load dump spikes to ≤234V, preventing damage to 36V-rated input MOSFETs and enabling compliance with ISO 7637-2 Pulse 5a. | Use Scenario: LIN bus transceiver interface in door module subjected to ESD and battery reversal transients. IC Role / Device Role / Timing Role: Bidirectional TVS connected between LIN line and chassis ground, adjacent to transceiver pins. Use Value: Absorbs ±8kV contact ESD per IEC 61000-4-2 without latch-up, maintaining LIN communication integrity during vehicle assembly and service. |
| RS-485 Data Line Protection | AC-DC Adapter Surge Suppression |
Use Scenario: Two-wire RS-485 trunk line in building automation system running alongside AC mains wiring. IC Role / Device Role / Timing Role: Bidirectional TVS pair (one per line) referenced to signal ground, placed at connector entry point. Use Value: Limits common-mode surges to <234V differential swing, preserving receiver input range and meeting EN 61000-4-5 Level 3 (2kV) | Use Scenario: Secondary-side DC output of 12V/3A wall adapter subject to lightning-induced surges on connected USB peripherals. IC Role / Device Role / Timing Role: TVS mounted across output terminals, downstream of output capacitor. Use Value: Prevents overvoltage propagation to USB-PD controllers by clamping 1kV/0.5J transients within 100ns, avoiding brownout resets. |
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 VRWM/VBR/VC ratings but in SMB surface-mount package (lower profile, higher thermal resistance RθJA = 100°C/W) | Preferred for space-constrained PCBs where reflow compatibility and reduced height are critical | Select when automated SMT assembly is required and board real estate is limited; verify thermal relief pad design for 5W steady-state dissipation |
| 1.5KE170CA | Same electrical specs but 1500W peak power rating and larger DO-201AD package (higher surge margin, slower thermal response) | Used where multi-pulse surge endurance or legacy through-hole footprint compatibility is mandatory | Choose for mission-critical systems requiring >2× pulse energy headroom or where existing DO-201AD tooling exists |
Compared with SMBJ170CA and 1.5KE170CA, P6KE170CA-T offers optimal balance of cost, axial-leaded manufacturability, and 600W surge handling for mid-tier industrial and automotive applications-neither over-specified nor thermally marginal in standard PCB layouts.

FAQ
What does the "CA" suffix indicate in P6KE170CA-T?
The "CA" suffix denotes a bidirectional TVS configuration: the device provides symmetrical clamping for positive and negative transients, with no designated anode or cathode. Unlike unidirectional "A" variants, it lacks a cathode band marking and is used where polarity of incoming surges is undefined-such as AC lines, differential buses, or floating sensors.
Can P6KE170CA-T replace a unidirectional P6KE170A-T in a DC power rail?
No-P6KE170CA-T is not a drop-in replacement for unidirectional P6KE170A-T in DC applications. The bidirectional version conducts during negative voltage excursions, potentially causing unintended current paths or latch-up in circuits with grounded references. Use only P6KE170A-T for standard DC rail protection unless the design explicitly requires dual-polarity clamping.
What is the maximum recommended PCB trace length between P6KE170CA-T and protected IC?
For effective protection, keep PCB traces from P6KE170CA-T to the protected node and to ground under 5mm total loop length. Longer traces add inductance that increases clamping voltage during fast transients; measured data shows >10mm trace length can raise VC by 15–25V under 8/20μs surge conditions, risking downstream component overstress.
Is P6KE170CA-T qualified to AEC-Q101 for automotive use?
No-P6KE170CA-T is not AEC-Q101 qualified. While Diodes offers AEC-Q101 versions in the same P6KE family (e.g., P6KE170CAQ-T), this specific part number is standard-grade. For automotive applications requiring qualification, consult Diodes' automotive product line or request PPAP documentation for Q-grade equivalents before design-in.
