Product details
Overview
P4KE100C-E3/73 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features a 85.5 V stand-off voltage (VWM), 95–105 V breakdown voltage (VBR) at 1 mA test current, 137 V maximum clamping voltage at 2.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P4KE100C-E3/73 datasheet, P4KE100C-E3/73 pinout, P4KE100C-E3/73 application, or P4KE100C-E3/73 equivalent, key selection criteria include bidirectional clamping capability, DO-41 leaded package compatibility, AEC-Q101 qualification status, 175 °C maximum junction temperature, and suitability for automotive sensor line protection against inductive switching surges.
Technical Context
This device operates as a voltage-clamping protector in bidirectional configurations, responding to transient overvoltages in either polarity without requiring external polarity management. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, enabling consistent clamping performance across repetitive 10/1000 μs pulses at 0.01% duty cycle.
The P4KE100C-E3/73 exhibits a temperature coefficient of breakdown voltage of +0.106 %/°C and maintains ≤1.0 μA reverse leakage at VWM, supporting reliable operation in industrial and automotive environments where thermal drift and leakage sensitivity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 85.5 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR min/max | 95 V / 105 V at 1 mA - Confirmed breakdown range ensuring predictable turn-on during transients; supports design margining. |
| VC @ IPPM | 137 V at 2.9 A - Clamped voltage under standardized 10/1000 μs surge; determines protected circuit's maximum stress level. |
| PPPM | 400 W - Peak pulse power handling with 10/1000 μs waveform; enables robust suppression of common ESD and load-dump events. |
| TJ max | +175 °C - Maximum junction temperature rating; allows operation in under-hood automotive and high-ambient industrial settings. |
| RθJL | 66 °C/W - Junction-to-lead thermal resistance; informs heatsinking requirements when mounted on PCB with standard lead length. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive electronics, including temperature cycling, HTRB, and surge endurance. |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy body with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. No polarity marking - bidirectional functionality eliminates cathode/anode distinction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked) | Transient conduction path | Both terminals conduct equally during positive or negative transients; no DC bias polarity dependency. |
| Leads (anode & cathode) | Thermal and electrical interface | Provide mechanical mounting, heat dissipation path (RθJL = 66 °C/W), and low-inductance connection to PCB traces. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR over time and temperature, minimizing parameter drift in long-life automotive applications. |
| 400 W peak pulse power (10/1000 μs) | Handles typical ISO 7637-2 Load Dump Pulse 5a (up to 130 V, 100 ms) with margin when combined with upstream impedance. |
| AEC-Q101 qualification | Validates reliability for automotive use cases including engine control units, body electronics, and ADAS sensor interfaces. |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed modules in consumer, industrial, and automotive enclosures. |

IC Role / Device Role / Timing Role: Standoff protector on input terminal block, conducting only during >85.5 V events to prevent latch-up or damage to optocoupler input stages. Use Value: Enables compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) up to 1 kV/42 Ω when used with series impedance. |
| Telecom Line Interface | Consumer Power Adapter Input |

Use Value: Provides cost-effective, RoHS-compliant (E3 suffix) protection without requiring active control or additional biasing circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Surface-mount SMB package (vs. through-hole DO-41); same 100 V VWM, 137 V VC, but 600 W PPPM rating. | Better suited for high-density PCBs and automated assembly; lacks AEC-Q101 qualification in standard grade. | Select SMBJ100CA when board space is constrained and higher pulse power margin is required; verify layout thermal relief for SMB footprint. |
| 1.5KE100CA | Higher 1500 W PPPM rating, same DO-41 package and 100 V VWM; larger case volume and higher VF (5.0 V). | Preferred for severe surge environments (e.g., industrial motor drives) where 400 W is insufficient. | Choose 1.5KE100CA when system-level surge testing exceeds IEC 61000-4-5 Level 4; note increased physical size and lead spacing. |
Compared with P4KE100C-E3/73, SMBJ100CA offers superior power density and SMT compatibility but requires requalification for AEC-Q101, while 1.5KE100CA delivers triple the pulse power in the same through-hole form factor-making it ideal for legacy DO-41 designs needing enhanced ruggedness.

FAQ
What is the polarity configuration of the P4KE100C-E3/73?
The P4KE100C-E3/73 is a bidirectional TVS diode with no polarity marking on its DO-41 package. Its "C" suffix explicitly denotes bidirectional operation, meaning it clamps overvoltage transients of either polarity symmetrically across its terminals - unlike unidirectional variants (e.g., P4KE100A) that require correct anode/cathode orientation.
Does the P4KE100C-E3/73 meet automotive qualification standards?
Yes, the P4KE100C-E3/73 is AEC-Q101 qualified, as confirmed in Vishay's official documentation (Document Number: 88365, Revision: 16-Sep-2021). This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and surge endurance - validating its suitability for automotive applications such as engine control, body electronics, and ADAS sensor interfaces.
What is the maximum clamping voltage of the P4KE100C-E3/73 under surge conditions?
The P4KE100C-E3/73 has a maximum clamping voltage (VC) of 137 V at 2.9 A peak pulse current, measured using the standardized 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuits during transient events and is critical for ensuring downstream components (e.g., 100 V-rated MOSFETs or CAN transceivers) remain within safe operating limits.
How does the P4KE100C-E3/73 differ from the unidirectional P4KE100A-E3/73?
The P4KE100C-E3/73 is bidirectional with symmetrical clamping in both polarities and no cathode band marking, whereas the P4KE100A-E3/73 is unidirectional, features a cathode band, and conducts only during reverse-biased transients. Their VWM (85.5 V), VBR (95–105 V), and VC (137 V) are identical, but the "C" variant eliminates polarity-dependent layout constraints and supports AC-coupled or floating-line protection.
What is the thermal resistance specification for the P4KE100C-E3/73?
The P4KE100C-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, measured with standard lead length (10 mm). This parameter governs how effectively heat generated during surge events transfers from the silicon junction to the PCB copper or heatsink via the leads - essential for estimating safe repetition rates and verifying thermal performance in high-ambient environments like automotive under-hood locations.
