Product details
Overview
P6KE100-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 95.0 V to 105 V breakdown voltage (VBR), 85.5 V maximum standoff voltage (VWM), 137 V clamping voltage at 4.4 A peak pulse current, 600 W peak pulse power rating (10/1000 μs waveform), and operates across –55 °C to +175 °C junction temperature range - deployed in automotive power supply inputs and industrial sensor interface circuits.
For engineers reviewing the P6KE100-E3/73 datasheet, P6KE100-E3/73 pinout, P6KE100-E3/73 application, or P6KE100-E3/73 equivalent, this page delivers verified electrical parameters, DO-204AC package details, clamping behavior under surge conditions, thermal resistance data, and validated alternative parts for ESD/surge protection design-in.
Technical Context
The P6KE100-E3/73 implements an avalanche breakdown mechanism in a glass-passivated silicon junction, enabling sub-nanosecond response to transients. Its unidirectional polarity uses a cathode band marking and exhibits 3.5 V forward voltage at 50 A, with 100 A non-repetitive surge capability (8.3 ms half-sine).
Thermal performance is defined by 20 °C/W junction-to-lead resistance and 75 °C/W junction-to-ambient resistance, supporting operation up to 175 °C. The device complies with AEC-Q101 for automotive-grade reliability and meets UL 94 V-0 flammability requirements in its molded epoxy DO-204AC housing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 95.0 V / 105 V - ensures reliable conduction onset above normal operating voltage while avoiding false triggering |
| VWM | 85.5 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 137 V at 4.4 A - clamped voltage during 10/1000 μs transient, limiting downstream stress |
| PPPM | 600 W - peak surge power handling capacity under standardized lightning/surge waveform |
| IFSM | 100 A - single half-sine surge current rating (8.3 ms), critical for inductive load switching events |
| TJ max. | +175 °C - enables use in under-hood automotive and high-temperature industrial environments |
| RθJL | 20 °C/W - low thermal resistance supports effective heat transfer to PCB copper or heatsinked leads |

|---|---|
Use Scenario: 12 V battery-fed ECUs exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Primary clamping element placed between power rail and ground, absorbing >90 % of surge energy before reaching downstream regulators.

Use Scenario: 4–20 mA current loop sensors in factory automation subject to ESD and cable-induced surges. IC Role / Device Role / Timing Role: Bidirectional protection (with series resistor) on analog input pins of ADC front-end or isolation amplifier. Use Value: Clamps transients to <140 V within nanoseconds, preserving 16-bit measurement accuracy and preventing latch-up in precision op-amps. |
| Telecom DC Power Feeds | Consumer Appliance Motor Drive Inputs |
Use Scenario: PoE-powered network switches with 48 V DC input susceptible to lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: First-stage TVS on main DC input before DC/DC converter, coordinated with MOV and fuse. Use Value: Withstands 600 W pulses without degradation, maintaining <1 μA leakage at 41 V nominal, ensuring no standby power loss. |
Use Scenario: Brushed DC motor control boards in washing machines experiencing commutation spikes up to 200 V. IC Role / Device Role / Timing Role: Unidirectional clamp across motor terminals or H-bridge supply rail to suppress inductive kickback. Use Value: Absorbs 100 A surge (8.3 ms) without failure, enabling compliance with IEC 60335-1 motor surge immunity requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | DO-214AA package (smaller footprint), 100 V VWM, 160 V VC @ 3.8 A, same 600 W rating | Preferred where board space is constrained; higher clamping voltage reduces margin for 100 V-rated downstream ICs | Select SMBJ100A when layout density is critical and clamping headroom ≥60 V is acceptable |
| 1.5KE100A | Same DO-204AC package, identical VBR/VWM/VC specs, but rated for 1.5 kW peak power (10/1000 μs) | Suitable for higher-energy surge environments (e.g., outdoor telecom); larger thermal mass requires longer lead lengths for derating | Choose 1.5KE100A when system-level surge testing exceeds IEC 61000-4-5 Level 4 |
Compared with SMBJ100A and 1.5KE100A, the P6KE100-E3/73 offers optimal balance of proven automotive qualification, industry-standard DO-15 mounting compatibility, and cost-effective 600 W surge handling - making it ideal for volume production in mid-tier industrial and automotive modules where AEC-Q101 compliance and legacy board layouts are mandatory.

FAQ
What is the clamping voltage of the P6KE100-E3/73 under standard surge conditions?
The P6KE100-E3/73 has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 4.4 A using the 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that downstream components see no more than 137 V during transient events - a critical parameter for protecting 100 V-rated capacitors and 150 V MOSFETs. The P6KE100-E3/73 maintains this clamping performance across its full operating temperature range.
Is the P6KE100-E3/73 suitable for automotive applications?
Yes, the P6KE100-E3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and infotainment power supplies. Its –55 °C to +175 °C operating junction temperature range, glass-passivated junction, and DO-204AC construction meet stringent automotive reliability requirements. The P6KE100-E3/73 is commonly deployed in 12 V and 24 V vehicle subsystems to suppress load dump and ISO 7637-2 transients.
How does the P6KE100-E3/73 differ from bi-directional TVS diodes like P6KE100CA?
The P6KE100-E3/73 is unidirectional and features a cathode band marking; it conducts only in reverse bias above VBR, with forward voltage ~3.5 V at 50 A. In contrast, P6KE100CA is bi-directional, symmetric in both polarities, and lacks polarity marking. The P6KE100-E3/73 is used on DC rails where polarity is fixed, while P6KE100CA suits AC-coupled or floating signal lines. Their VBR and VC values differ slightly due to internal structure.
What is the thermal resistance of the P6KE100-E3/73, and how does it affect PCB layout?
The P6KE100-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. To maintain safe operation under repetitive surges, PCB layout must provide adequate copper area on both leads - minimum 100 mm² per lead recommended. Short, wide traces and thermal vias improve heat dissipation. The P6KE100-E3/73's thermal profile directly impacts its ability to sustain multiple 600 W pulses without exceeding 175 °C junction temperature.
Does the P6KE100-E3/73 comply with RoHS and halogen-free standards?
Yes, the P6KE100-E3/73 carries the "E3" suffix indicating full RoHS compliance per Directive 2011/65/EU and halogen-free status per JEDEC JS709A. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the UL 94 V-0 epoxy molding compound contains no brominated flame retardants. These certifications are documented in Vishay's material declarations and apply to all units shipped under the P6KE100-E3/73 part number.
