Product details
Overview
P4KE100C-E3/54 from Vishay General Semiconductor is a bidirectional TransZORB® transient voltage suppressor (TVS) diode designed for clamping inductive and lightning-induced surges on signal and power lines. It features a 100 V breakdown voltage (VBR min/max = 95.0–105 V), 85.5 V standoff voltage (VWM), 137 V maximum clamping voltage (VC) at 2.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, sensor interfaces, and automotive control modules.
For engineers reviewing the P4KE100C-E3/54 datasheet, P4KE100C-E3/54 pinout, P4KE100C-E3/54 application, or P4KE100C-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 package compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 66 °C/W), and low leakage (<1 µA at VWM) in harsh ambient environments.
Technical Context
This device operates as a voltage-clamping protection element in both polarities, leveraging an avalanche breakdown mechanism to divert transient energy away from sensitive downstream circuitry. Its bidirectional symmetry ensures identical electrical behavior regardless of polarity, eliminating need for orientation-specific layout placement.
The P4KE100C-E3/54 delivers stable clamping performance across -55 °C to +175 °C junction temperature range, with 0.106 %/°C temperature coefficient of VBR and 1.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C - enabling reliable operation in under-hood automotive and industrial motor drive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 95.0 V / 105 V - defines guaranteed avalanche conduction onset window under 1 mA test current |
| VWM | 85.5 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 137 V at 2.9 A - clamped voltage during 10/1000 µs surge, limiting stress on protected ICs |
| PPPM | 400 W - peak transient power handling capacity without degradation under standard waveform |
| IFSM | Not applicable - bidirectional type has no forward surge rating; only unidirectional variants specify 40 A |
| TJ max | +175 °C - enables deployment in high-temperature engine compartments and industrial enclosures |
| RθJL | 66 °C/W - thermal resistance from junction to lead, critical for PCB copper pour design and power derating |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy body with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102 solderability standards. No polarity marking - bidirectional construction eliminates cathode/anode distinction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path terminal | Either lead conducts surge current equally in either direction; no orientation required during placement |
| Leads (both) | Thermal and mechanical interface | Provide primary heat conduction path to PCB copper; RθJL = 66 °C/W assumes 10 mm lead length |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable VBR tolerance and long-term reliability under humidity and thermal cycling |
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTOL, TC, and UHAST |
| 400 W 10/1000 µs pulse rating | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly decoupled and routed |
| UL 94 V-0 molding compound | Meets flammability safety requirement for enclosed industrial and transportation equipment |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns response time) |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Bidirectional clamping TVS placed at power entry point before DC/DC converter input. Use Value: Clamps surges up to 137 V while maintaining <1 µA leakage at 85.5 V, preserving low-quiescent-current design. |
Use Scenario: Shielding analog front-end of pressure/temperature sensors in PLC I/O modules from ESD and inductive kickback. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor on differential signal pair (e.g., RS-485 bus lines). Use Value: Symmetric clamping prevents signal inversion during bipolar transients; DO-41 footprint allows manual rework and automated placement. |
| Consumer Appliance Motor Drive Protection | Telecom Power Supply Input Protection |
Use Scenario: Safeguarding BLDC motor controller gate drivers from back-EMF spikes during commutation. IC Role / Device Role / Timing Role: Parallel-connected TVS across half-bridge supply rails to clamp inductive energy recirculation. Use Value: 175 °C max junction temperature supports operation near heatsinks; 66 °C/W RθJL enables thermal coupling to copper pour. |
Use Scenario: Front-end surge suppression on AC/DC adapter inputs subjected to lightning-induced line surges. IC Role / Device Role / Timing Role: Primary-level TVS in conjunction with MOV and fuse for coordinated overvoltage protection. Use Value: 400 W peak pulse rating handles repetitive 10/1000 µs events per IEC 61000-4-5; RoHS-compliant E3 suffix meets global compliance mandates. |
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. axial DO-41); same VBR range and 600 W PPPM | Requires PCB redesign for SMT assembly; higher power rating suits higher-energy surge environments | Select when board space is constrained and automated SMT production is preferred over through-hole |
| 1.5KE100CA | Higher 1500 W PPPM, same DO-41 package but larger body (DO-201AE); VC = 156 V at 9.4 A | Delivers greater surge margin but increases VC by 19 V - may exceed protected IC's absolute max rating | Choose only if system-level testing confirms 156 V clamping remains within safe operating area of downstream components |
Compared with SMBJ100CA and 1.5KE100CA, the P4KE100C-E3/54 offers optimal balance of proven through-hole manufacturability, AEC-Q101 qualification, and precise 137 V clamping - making it ideal for cost-sensitive, thermally demanding, and automotive-grade designs where layout flexibility and qualification traceability are prioritized.

FAQ
What is the polarity configuration of P4KE100C-E3/54?
The P4KE100C-E3/54 is a bidirectional TVS diode with symmetrical avalanche characteristics in both directions. Unlike unidirectional variants (e.g., P4KE100A), it has no cathode marking and functions identically regardless of terminal orientation - simplifying layout and eliminating polarity-check steps during assembly.
Does P4KE100C-E3/54 meet automotive qualification standards?
Yes, the P4KE100C-E3/54 carries the HE3 suffix variant (P4KE100CHE3/54) that is AEC-Q101 qualified. While the E3/54 version is commercial-grade, its construction - glass-passivated junction, UL 94 V-0 epoxy, and 175 °C TJ rating - aligns with automotive thermal and reliability requirements when validated per application.
What is the maximum clamping voltage of P4KE100C-E3/54 under surge conditions?
The P4KE100C-E3/54 exhibits a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 2.9 A using the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88365 and defines the upper voltage limit imposed on protected circuitry during transient events.
Can P4KE100C-E3/54 be used in place of unidirectional P4KE100A?
No - P4KE100C-E3/54 and P4KE100A serve distinct circuit roles. The "C" suffix denotes bidirectional operation, while "A" indicates unidirectional. Substituting one for the other risks improper clamping during reverse-polarity transients or unintended forward conduction; design intent and schematic symbol must match the device's polarity specification.
What packaging format is supplied for P4KE100C-E3/54?
P4KE100C-E3/54 is supplied in 13-inch diameter paper tape and reel packaging with a base quantity of 5,500 units per reel (package code 54). The E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance, supporting lead-free reflow and wave soldering processes.
