Product details
Overview
P6KE110A-E3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 105 V to 116 V breakdown voltage (VBR), 94.0 V maximum standoff voltage (VWM), 152 V clamping voltage at 3.9 A peak pulse current (VC @ IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive engine control units, industrial PLC I/O modules, and telecom power supply inputs.
For engineers reviewing the P6KE110A-E3/73 datasheet, P6KE110A-E3/73 pinout, P6KE110A-E3/73 application, or P6KE110A-E3/73 equivalent, key selection criteria include verified unidirectional polarity, DO-15 package thermal resistance (RθJL = 20 °C/W), 175 °C max junction temperature, and compliance with AEC-Q101 for automotive-grade reliability.
Technical Context
The P6KE110A-E3/73 operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to clamp transient overvoltages before sensitive downstream circuitry is damaged. Its unidirectional configuration provides reverse-biased protection only, with cathode marked by color band and forward voltage drop of 3.5 V at 50 A.
It is rated for 600 W peak pulse power under 10/1000 μs waveform at 0.01% duty cycle, derated linearly above 25 °C ambient per Fig. 2, and supports repetitive surge events within thermal limits defined by RθJA = 75 °C/W and RθJL = 20 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V to 116 V - ensures reliable avalanche conduction onset across manufacturing tolerance and temperature range |
| VWM | 94.0 V - maximum continuous DC or RMS operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 152 V at 3.9 A - clamped voltage seen by protected circuit during worst-case 10/1000 μs surge |
| PPPM | 600 W - peak transient energy absorption capability without failure under standardized waveform |
| TJ max | +175 °C - enables operation in under-hood automotive or high-temperature industrial environments |
| RθJL | 20 °C/W - low thermal resistance from junction to lead supports sustained power dissipation when PCB copper acts as heatsink |
| IFSM | 100 A - non-repetitive 8.3 ms surge current rating for lightning or inductive switch-off events |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode identified by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during forward surge or bias |
| Cathode | Avalanche clamping terminal | Marked with color band; connected to protected line (e.g., +12 V rail); avalanches into conduction when reverse voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|

| 600 W peak pulse power (10/1000 μs) | Provides robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 3 surges |
| AEC-Q101 qualified | Validated for automotive applications including powertrain, body electronics, and ADAS sensor interfaces |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes overvoltage stress on downstream MOSFETs, regulators, and microcontrollers during clamping |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance and UL 94 V-0 flammability requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | Same VBR range (105–116 V), but SMC (DO-214AB) package; 600 W rating; lower RθJA (50 °C/W) | Surface-mount layout; better thermal performance on dense PCBs; not axial-leaded | Select SMBJ110A when board space is constrained and reflow assembly is used. |
| 1.5KE110A | Same DO-15 package and VBR, but 1500 W rating (10/1000 μs); higher IPPM (10.5 A); larger junction capacitance | Higher-energy surge environments (e.g., outdoor telecom cabinets); less suitable for high-speed signal lines | Choose 1.5KE110A where IEC 61000-4-5 Level 4 immunity is required and size permits. |
Compared with SMBJ110A and 1.5KE110A, the P6KE110A-E3/73 offers optimal balance of axial-leaded serviceability, AEC-Q101 qualification, and cost-effective 600 W protection - ideal for mid-tier automotive and industrial designs where leaded assembly and proven field reliability are prioritized.

FAQ
What is the breakdown voltage range specified for P6KE110A-E3/73?
The P6KE110A-E3/73 has a guaranteed breakdown voltage (VBR) range of 105 V to 116 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range reflects production tolerance and ensures consistent clamping behavior across temperature and unit-to-unit variation. The value is confirmed in Vishay's official datasheet document 88369, revision 27-Sep-2021.
Is P6KE110A-E3/73 suitable for automotive applications?
Yes, P6KE110A-E3/73 is AEC-Q101 qualified and explicitly listed in Vishay's documentation as meeting automotive reliability requirements. Its 175 °C maximum junction temperature, glass-passivated junction, and robust surge ratings make it appropriate for engine control units, body control modules, and infotainment power supplies. The E3/73 suffix denotes RoHS compliance and tape-and-reel packaging compatible with automated assembly.
What does the "A" suffix indicate in P6KE110A-E3/73?
The "A" suffix in P6KE110A-E3/73 designates a unidirectional TVS diode configuration - meaning it provides avalanche clamping only in reverse bias, with forward conduction limited to ~3.5 V at 50 A. This distinguishes it from bidirectional variants (e.g., P6KE110CA), which protect both polarities and lack cathode marking. The "A" is part of Vishay's standardized naming convention for unidirectional TRANSZORB® devices.
What is the maximum clamping voltage of P6KE110A-E3/73 under surge conditions?
The maximum clamping voltage (VC) of P6KE110A-E3/73 is 152 V at 3.9 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value represents the upper limit of voltage imposed on protected circuitry during worst-case transient events and is critical for verifying compatibility with downstream IC absolute maximum ratings. It is measured per Figure 1 and Table on page 2 of datasheet 88369.
How is thermal performance characterized for P6KE110A-E3/73?
P6KE110A-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. These values define its ability to dissipate surge energy without exceeding 175 °C junction temperature. Effective heat sinking via PCB copper land patterns connected to leads significantly improves sustained power handling - validated in Vishay's Fig. 5 power derating curve.
