Product details
Overview
P6KE170C-E3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection on signal and power lines. It features a 170 V breakdown voltage (VBR min = 162 V, max = 179 V), 145 V stand-off voltage (VWM), 234 V clamping voltage at 2.6 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection circuits.
For engineers reviewing the P6KE170C-E3/73 datasheet, P6KE170C-E3/73 pinout, P6KE170C-E3/73 application, or P6KE170C-E3/73 equivalent, key selection criteria include its bi-directional polarity, DO-204AC (DO-15) package, AEC-Q101 qualification, low 0.108 %/°C temperature coefficient of VBR, and suitability for inductive load switching transients in harsh environments.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), but triggers into low-impedance conduction when transient voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and fast response (<1 ns), critical for protecting MOSFET gates and microcontroller I/O pins against ESD and lightning-induced surges.
The bi-directional configuration enables symmetric clamping in AC-coupled or floating signal paths without polarity constraints. Thermal resistance is characterized at RθJL = 20 °C/W (junction-to-lead), supporting reliable power dissipation up to 5.0 W on infinite heatsink at TL = 75 °C - validated per JESD 22-B106 solderability and JESD 201 class 1A whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 162 V / 179 V at 1.0 mA test current - defines precise voltage threshold for reliable clamping onset across temperature and unit variation |
| VWM | 145 V - maximum continuous working voltage before leakage exceeds 1.0 µA, ensuring no false triggering in nominal operation |
| VC @ IPPM | 234 V at 2.6 A (10/1000 µs) - limits protected circuit voltage during worst-case surge, enabling downstream component survival |
| PPPM | 600 W - peak transient energy absorption capacity, sufficient for automotive load-dump and industrial relay-coil flyback events |
| TJ max | +175 °C - extended junction temperature rating supports under-hood and high-ambient industrial deployments |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with UL 94 V-0 molded epoxy, compatible with through-hole assembly |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness per stress test plan |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy body, matte tin-plated leads. No polarity marking - bi-directional symmetry eliminates cathode/anode orientation concerns during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Bi-directional conduction allows identical clamping behavior regardless of voltage polarity - simplifies layout on differential or AC lines |
| Lead 1 | Junction-to-lead thermal path | Primary heat dissipation route; RθJL = 20 °C/W enables effective thermal management via PCB copper pour or heatsink contact |
| Lead 2 | Current return path | Completes low-inductance surge path to ground or rail; lead length ≤ 9.5 mm specified for rated IFSM performance |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance (±5 %) and long-term parameter drift <1 % over 1000 hrs at TJ = 125 °C |
| 600 W peak pulse power (10/1000 µs) | Withstands repetitive 0.01 % duty cycle surges - suitable for motor drive feedback lines subject to frequent commutation spikes |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on protected ICs; e.g., keeps 3.3 V MCU I/O below 5 V absolute max during 1 kV EFT burst |
| AEC-Q101 qualification | Validates operation across -55 °C to +175 °C, 1000-cycle temperature cycling, and 78 kV/m HBM ESD - required for automotive body control modules |
| RoHS-compliant, matte tin plating | Meets J-STD-002 solderability and JESD 201 class 1A whisker resistance - ensures reliability in lead-free reflow and long-life applications |
Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |

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, lower RθJA (50 °C/W vs. 75 °C/W) | Requires PCB redesign for SMT assembly; better suited for space-constrained designs with automated placement | Select SMBJ170CA when board real estate is limited and thermal vias can be implemented for enhanced cooling |
| 1.5KE170CA | Higher peak pulse power (1500 W), same DO-204AC package; larger chip die, higher IPPM (5.2 A vs. 2.6 A), VC = 274 V | Over-spec'd for most 600 W use cases; introduces higher clamping voltage and greater thermal mass | Choose 1.5KE170CA only when legacy systems require backward-compatible footprint with headroom for future surge severity increases |
Compared with SMBJ170CA and 1.5KE170CA, P6KE170C-E3/73 delivers optimal cost-performance balance for through-hole automotive and industrial applications where AEC-Q101 validation, proven DO-15 reliability, and precise 234 V clamping are prioritized over ultra-high power or miniaturization.

FAQ
What is the breakdown voltage tolerance for P6KE170C-E3/73?
The P6KE170C-E3/73 has a guaranteed breakdown voltage range of 162 V to 179 V at 1.0 mA test current, corresponding to a ±5 % tolerance around the nominal 170 V rating. This tight VBR spread ensures consistent clamping behavior across production lots and temperature extremes, critical for predictable system-level surge protection design using the P6KE170C-E3/73.
Is P6KE170C-E3/73 suitable for automotive applications?
Yes, P6KE170C-E3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its -55 °C to +175 °C operating range, validated temperature cycling, and HTRB performance make it appropriate for engine control units, body electronics, and sensor interfaces where the P6KE170C-E3/73 provides certified transient immunity per ISO 7637-2 and ISO 16750-2.
How does the bi-directional nature of P6KE170C-E3/73 affect its circuit placement?
The bi-directional construction of P6KE170C-E3/73 means it has no anode/cathode marking and conducts identically in both voltage polarities. This allows direct placement across AC-coupled lines, transformer secondaries, or floating differential pairs without orientation checks - simplifying assembly and eliminating risk of reverse installation that could compromise protection when using uni-directional variants like P6KE170A.
What is the maximum clamping voltage of P6KE170C-E3/73 under surge conditions?
The P6KE170C-E3/73 clamps to a maximum of 234 V when subjected to its rated 2.6 A peak pulse current (IPPM) with a 10/1000 µs waveform. This VC value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during standardized surge events - a key parameter used to verify safe operation margins for downstream components in designs using the P6KE170C-E3/73.
Does P6KE170C-E3/73 meet RoHS and lead-free assembly requirements?
Yes, P6KE170C-E3/73 carries the "E3" suffix indicating full RoHS compliance and compatibility with lead-free reflow processes. Its matte tin-plated leads meet J-STD-002 solderability standards and JESD 201 class 1A whisker resistance requirements, ensuring reliable interconnect integrity in modern manufacturing flows where the P6KE170C-E3/73 is deployed in high-volume consumer and industrial products.
