Product details
Overview
P6KE170C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in 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, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the P6KE170C-E3/54 datasheet, P6KE170C-E3/54 pinout, P6KE170C-E3/54 application, or P6KE170C-E3/54 equivalent, key selection criteria include verified bi-directional clamping performance, DO-15 package thermal resistance (RθJA = 75 °C/W), AEC-Q101 qualification status, and compliance with UL 497B for telecom protectors.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, delivering identical clamping behavior during positive and negative transients. Its glass-passivated junction ensures stable VBR tolerance (±5 %), low incremental surge resistance, and fast response time (<1 ns) to ESD and lightning-induced surges.
The device is rated for 175 °C maximum junction temperature and supports repetitive 10/1000 µs pulses at 0.01 % duty cycle. Its thermal resistance profile (RθJL = 20 °C/W) enables reliable operation under sustained transient stress when mounted on standard PCB copper land patterns.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ170CA | Same VBR range (162–179 V) but SMB package (smaller footprint, higher RθJA = 110 °C/W) | Preferred for space-constrained designs; requires tighter thermal layout due to lower power dissipation margin | Select when board area is critical and transient energy is ≤400 W; verify thermal relief pad design per JEDEC Std. 51-3 |
| 1.5KE170CA | Higher PPPM = 1500 W, same DO-15 package, VC = 274 V at 5.5 A | Better suited for high-energy industrial surges (IEC 61000-4-5 6 kV); higher clamping voltage increases risk to sensitive loads | Choose when system-level surge testing exceeds 4 kV; accept trade-off of elevated clamping voltage for enhanced robustness |
Compared with SMBJ170CA and 1.5KE170CA, P6KE170C-E3/54 delivers optimal balance of 600 W surge capability, 234 V clamping, and AEC-Q101 qualification in the proven DO-15 form factor - making it ideal for cost-sensitive automotive and industrial designs requiring certified reliability without over-engineering.

FAQ
What is the polarity configuration of P6KE170C-E3/54?
P6KE170C-E3/54 is a bi-directional TVS diode with symmetrical conduction characteristics in both directions. Unlike uni-directional variants (e.g., P6KE170A), it has no cathode marking and functions identically for positive and negative transients - essential for protecting AC-coupled or differential signal paths where polarity reversal occurs.
Is P6KE170C-E3/54 qualified for automotive applications?
Yes, P6KE170C-E3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and ESD per JESD22-A114. This certification confirms its suitability for under-hood and cabin electronics such as body control modules and sensor signal conditioning circuits where reliability under thermal and electrical stress is mandatory.
What does the "C" suffix indicate in P6KE170C-E3/54?
The "C" in P6KE170C-E3/54 denotes bi-directional functionality. Per Vishay's naming convention, "CA" indicates bi-directional types (e.g., P6KE170CA), and the "C" here is consistent with that designation - confirming symmetrical breakdown and clamping behavior. The "E3/54" suffix specifies RoHS-compliant matte tin plating and packaging in 13″ paper tape reels of 4000 units.
How does P6KE170C-E3/54 compare to P6KE170A in circuit protection?
P6KE170C-E3/54 provides bi-directional clamping, while P6KE170A is uni-directional with a cathode band. In AC or floating signal lines, P6KE170C-E3/54 eliminates polarity-dependent installation errors and protects against both positive and negative surges without external circuitry - unlike P6KE170A, which would require back-to-back pairing for equivalent coverage.
What is the maximum clamping voltage of P6KE170C-E3/54 under rated surge conditions?
The maximum clamping voltage (VC) of P6KE170C-E3/54 is 234 V at 2.6 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per Figure 1 in the datasheet and represents the worst-case voltage imposed on protected circuitry during full-rated transient events - critical for verifying compatibility with downstream IC absolute maximum ratings.
