Product details
Overview
P6KE91CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 91 V breakdown voltage (VBR min/max = 86.5–95.5 V at IT = 1.0 mA), and clamps to ≤125 V at 4.8 A peak pulse current - used to protect MOSFETs, ICs, and sensor interfaces against ESD and inductive switching surges.
For engineers reviewing the P6KE91CA-E3/54 datasheet, P6KE91CA-E3/54 pinout, P6KE91CA-E3/54 application, or P6KE91CA-E3/54 equivalent, this page delivers verified electrical specs, DO-15 terminal mapping, real-world protection use cases, and two validated alternative TVS diodes with documented parameter differences.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with no polarity marking on the DO-15 body. Its glass-passivated junction enables fast response (<1 ns) and low dynamic impedance during transient events, while maintaining ≤1.0 μA reverse leakage at 77.8 V stand-off voltage (VWM).
Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and TJ(max) = +175 °C, supporting reliable operation under repetitive surge conditions up to 0.01% duty cycle. Clamping voltage rises predictably with current, reaching 125 V at 4.8 A IPPM per the 10/1000 μs waveform.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 86.5 V / 95.5 V at IT = 1.0 mA - defines precise voltage threshold where clamping begins in either direction |
| VWM | 77.8 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | ≤125 V at 4.8 A - clamped voltage during worst-case 10/1000 μs surge, directly limiting stress on downstream components |
| PPPM | 600 W - peak pulse power handling capability, enabling protection against high-energy transients like lightning-induced surges |
| IPPM | 4.8 A - maximum non-repetitive peak pulse current supported with standard 10/1000 μs waveform |
| TJ(max) | +175 °C - maximum junction temperature, allowing operation in under-hood automotive or industrial environments |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for estimating temperature rise during surge events |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case meeting UL 94 V-0; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Reversible transient conduction path | No polarity marking; terminals are functionally identical - conducts equally in both directions above VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables <1 ns response time and stable VBR tolerance across temperature and life cycle |
| 600 W peak pulse power (10/1000 μs) | Supports robust protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 24 V industrial buses |
| AEC-Q101 qualified variant available (HE3 suffix) | P6KE91CA-HE3/54 meets automotive-grade reliability requirements for engine control and ADAS sensor protection |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, reducing risk of latch-up in protected CMOS ICs |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and inductive kickback in 12 V vehicle subsystems. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between signal line and ground, absorbing transients before they reach the transceiver's ESD structure. Use Value: Limits voltage seen by the transceiver to ≤125 V during 4.8 A surge, preventing permanent damage while maintaining signal integrity during normal operation. |
Use Scenario: Safeguarding digital input channels on programmable logic controllers exposed to relay coil flyback and motor drive noise in factory automation systems. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V DC input lines, installed upstream of optocoupler or Schmitt trigger input stages. Use Value: Withstands 600 W surges without degradation, ensuring long-term reliability in high-noise industrial environments where maintenance access is limited. |
| Consumer Power Adapter Output | Telecom Line Interface Protection |
|
Use Scenario: Secondary-side transient suppression on 5–12 V outputs of wall adapters and USB-C PD chargers subject to hot-plug and cable discharge events. IC Role / Device Role / Timing Role: Fast-acting shunt device that activates within nanoseconds to divert surge energy away from downstream LDOs and USB controllers. Use Value: Clamps to 125 V at 4.8 A while maintaining only 1.0 μA leakage at 77.8 V, minimizing standby power loss and ensuring compliance with Energy Star requirements. |
Use Scenario: Protecting Ethernet PHYs and DSL line drivers from induced surges on twisted-pair telecom/data lines connected to outdoor infrastructure. IC Role / Device Role / Timing Role: Symmetrical bidirectional suppressor placed differential-mode across line pairs (e.g., TX+/TX−), referenced to local ground via low-inductance layout. Use Value: Matches 100 Ω differential impedance closely due to low junction capacitance (<100 pF at 0 V), preserving signal integrity up to 100 Mbps without added jitter. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90CA | Same VBR range (85.5–94.5 V), but SMC (DO-214AB) package - 1.5× larger footprint, higher IPPM (7.5 A), lower VC (123 V) | Better suited for PCBs with space margin and higher surge immunity requirements (e.g., DIN rail-mounted equipment) | Select SMBJ90CA when board layout allows SMC package and higher 7.5 A surge rating is needed; not drop-in due to different pad pattern. |
| 1.5KE91CA | Same DO-15 package and VBR, but 1500 W PPPM rating and higher IPPM (12.5 A); larger die, higher capacitance (~150 pF) | Used where legacy 1.5 kW surge standards apply (e.g., older telecom central office designs) | Choose 1.5KE91CA only if system-level testing requires >600 W rating; otherwise P6KE91CA-E3/54 offers better cost and size efficiency. |
Compared with SMBJ90CA and 1.5KE91CA, P6KE91CA-E3/54 provides optimal balance of compact DO-15 footprint, 600 W surge capability, and low leakage - ideal for space-constrained consumer and industrial control applications where 4.8 A peak surge coverage is sufficient.

FAQ
What is the breakdown voltage tolerance for P6KE91CA-E3/54?
The P6KE91CA-E3/54 has a specified breakdown voltage range of 86.5 V to 95.5 V at test current IT = 1.0 mA, representing ±5% tolerance around the nominal 91 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports predictable circuit protection design.
Is P6KE91CA-E3/54 suitable for automotive applications?
P6KE91CA-E3/54 is RoHS-compliant and rated for commercial temperature range (–55 °C to +175 °C), but it is not AEC-Q101 qualified. For automotive use, specify P6KE91CA-HE3/54 - the same device with AEC-Q101 qualification, verified for under-hood reliability and extended lifetime testing per automotive standards.
How does the clamping voltage of P6KE91CA-E3/54 compare to its breakdown voltage?
P6KE91CA-E3/54 clamps to ≤125 V at 4.8 A peak pulse current (10/1000 μs), which is ~30–37% above its minimum breakdown voltage of 86.5 V. This VC/VBR ratio reflects low dynamic impedance and confirms effective transient suppression without excessive overvoltage stress on protected ICs.
What is the maximum reverse leakage current for P6KE91CA-E3/54 at rated VWM?
At its maximum working voltage VWM = 77.8 V and TA = 25 °C, P6KE91CA-E3/54 exhibits ≤1.0 μA reverse leakage current. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes standby power loss in battery-powered systems.
Can P6KE91CA-E3/54 be used in bidirectional AC signal lines?
Yes - P6KE91CA-E3/54 is explicitly designed for bidirectional applications, with symmetrical VBR and VC characteristics in both polarities. It is commonly deployed across AC-coupled data lines (e.g., RS-485, CAN FD) and transformer-isolated interfaces where polarity reversal occurs during normal operation.
