Product details
Overview
P6KE170-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal 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 power supply inputs, industrial sensor interfaces, and telecom line protection.
For engineers reviewing the P6KE170-E3/73 datasheet, P6KE170-E3/73 pinout, P6KE170-E3/73 application, or P6KE170-E3/73 equivalent, key selection criteria include verified clamping performance under 2.6 A surge, DO-204AC (DO-15) package compatibility with manual or wave soldering, AEC-Q101 qualification status, and thermal resistance (RθJL = 20 °C/W) for lead-mounted thermal management.
Technical Context
This TVS operates as a silicon avalanche diode with glass-passivated junction, optimized for fast response (<1 ns) to transient overvoltages induced by inductive switching or ESD events. Its unidirectional polarity uses a cathode band marking and exhibits low incremental surge resistance, enabling precise clamping without significant voltage overshoot during 10/1000 μs surges.
The device is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient per Fig. 2; its 5.0 W steady-state power dissipation (PD) applies at 75 °C lead temperature (TL), and it supports 100 A non-repetitive forward surge current (IFSM) per 8.3 ms half-sine waveform - critical for handling load-dump transients in 12 V/24 V vehicle systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 162 V / 179 V at 1.0 mA test current - defines reliable avalanche initiation threshold across production lot |
| VWM | 145 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 234 V at 2.6 A (10/1000 μs) - clamping voltage limiting downstream component stress during surge |
| PPPM | 600 W - peak transient power absorption capability without failure under standardized surge waveform |
| RθJL | 20 °C/W - thermal resistance from junction to lead, enabling direct PCB trace heat sinking without heatsink |
| TJ max | 175 °C - maximum allowable junction temperature supporting operation in under-hood automotive environments |
| IFSM | 100 A - single half-sine surge current rating (8.3 ms), validating robustness against battery load-dump events |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected circuit (e.g., ground or return path) in unidirectional configuration |
| Cathode (banded end) | Avalanche clamping terminal | Connected to higher-potential side (e.g., +12 V rail); conducts when reverse voltage exceeds VBR, shunting surge to ground |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable avalanche characteristics and long-term reliability under thermal cycling |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth) in compact DO-15 footprint |
| AEC-Q101 qualified (HE3 suffix variant) | Validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD HBM ≥ 8 kV |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage margin between clamping and protected IC's absolute maximum rating |
| Solder dip rated 275 °C for 10 s | Ensures process compatibility with lead-free reflow and wave soldering without delamination or parameter shift |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ170A-E3/52 | DO-214AA package; 170 V VBR; 231 V VC @ 2.6 A; 600 W rating; same VWM (145 V) | Surface-mount footprint replaces through-hole DO-15; requires PCB redesign but enables automated assembly | Select when transitioning from through-hole to SMT manufacturing or when board space constraints prohibit axial components |
| 1.5KE170A | Same DO-204AC package; identical VBR/VWM/VC specs; 1500 W PPPM (10/1000 μs); higher IPPM (8.2 A) | Higher surge capacity suits harsher environments (e.g., heavy-duty truck alternator load dump) | Select when system-level surge testing exceeds 600 W requirement or when legacy 1.5KE footprint must be retained |
Compared with SMBJ170A-E3/52 and 1.5KE170A, the P6KE170-E3/73 offers optimal balance of proven automotive-grade reliability in axial form factor, cost-effective through-hole assembly, and validated 600 W surge handling - making it preferred for medium-risk industrial and Tier-2 automotive applications where SMT conversion is not required and 1500 W rating is unnecessary.

FAQ
What is the maximum clamping voltage of the P6KE170-E3/73 under standard surge conditions?
The P6KE170-E3/73 has a maximum clamping voltage (VC) of 234 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 2.6 A. This value is measured per industry-standard test conditions defined in the Vishay datasheet (Document Number: 88369), and represents the upper limit of voltage seen by downstream circuitry during a full-power transient event. The P6KE170-E3/73 maintains this clamping performance consistently across its specified operating temperature range.
Is the P6KE170-E3/73 RoHS compliant and halogen-free?
Yes, the P6KE170-E3/73 carries the "E3" suffix, indicating full RoHS compliance per Directive 2011/65/EU and adherence to JEDEC JS709A halogen-free standards. Its molding compound meets UL 94 V-0 flammability rating, and matte tin-plated leads satisfy J-STD-002 solderability requirements. The P6KE170-E3/73 is certified for commercial-grade applications and may be used in consumer, industrial, and automotive contexts where material compliance is mandated.
How does the P6KE170-E3/73 differ from the P6KE170AHE3/73 variant?
The P6KE170-E3/73 is the commercial-grade version, while P6KE170AHE3/73 adds AEC-Q101 qualification for automotive use. Both share identical electrical parameters (VBR, VWM, VC, PPPM) and DO-204AC packaging, but the HE3 variant undergoes extended stress testing including high-temperature operating life (HTOL), temperature cycling (TCT), and human-body-model ESD ≥ 8 kV. The P6KE170-E3/73 remains suitable for non-automotive applications where AEC-Q101 is not required.
Can the P6KE170-E3/73 be used in bidirectional configurations?
No - the P6KE170-E3/73 is a unidirectional TVS diode, identified by its cathode band marking. Bidirectional operation requires the "CA" suffix (e.g., P6KE170CA). Using the P6KE170-E3/73 in AC or symmetrical transient environments would result in forward conduction during negative half-cycles, potentially causing failure. For bidirectional protection at 170 V standoff, specify P6KE170CA or confirm alternate part numbers with CA designation.
What is the thermal resistance and maximum junction temperature rating of the P6KE170-E3/73?
The P6KE170-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and a maximum junction temperature (TJ) of 175 °C. These values enable effective heat dissipation through PCB copper traces connected to its leads, especially under intermittent surge conditions. The device's 5.0 W steady-state power dissipation is rated at 75 °C lead temperature, and derating follows the curve in Figure 5 of the Vishay datasheet (88369). This thermal profile makes the P6KE170-E3/73 suitable for under-hood automotive and industrial environments.
