Product details
Overview
P4KE110A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on DC power rails and signal lines. It features 110 V breakdown voltage (VBR min/max = 105–116 V), 94.0 V stand-off voltage (VWM), 152 V clamping voltage (VC) at 2.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs and ICs in automotive power supplies.
For engineers reviewing the P4KE110A-E3/54 datasheet, P4KE110A-E3/54 pinout, P4KE110A-E3/54 application, or P4KE110A-E3/54 equivalent, this page delivers verified electrical parameters, thermal derating behavior, DO-41 terminal polarity mapping, AEC-Q101 qualification status, and direct alternatives for overvoltage protection design validation.
Technical Context
The P4KE110A-E3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling fast response (<1 ns) to ESD and lightning-induced surges. Its unidirectional polarity uses cathode-band marking and exhibits 0.107 %/°C temperature coefficient of VBR, ensuring stable clamping across -55 °C to +175 °C junction range.
It delivers 400 W peak pulse power under 10/1000 μs waveform at 0.01 % duty cycle, with 1.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C. Thermal resistance is 66 °C/W (junction-to-lead) and 100 °C/W (junction-to-ambient, LLead = 10 mm), supporting reliable operation in constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1.0 mA test current - defines minimum voltage at which avalanche conduction begins reliably |
| VWM | 94.0 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 152 V at 2.6 A - clamped voltage during 10/1000 μs surge, limiting stress on downstream components |
| PPPM | 400 W - peak transient power handling capability, critical for IEC 61000-4-5 Level 3/4 surge immunity |
| TJ max | +175 °C - enables use in under-hood automotive environments without thermal shutdown |
| RθJL | 66 °C/W - low junction-to-lead thermal resistance supports high-reliability solder-joint thermal cycling |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; cathode indicated by color band on body end. Leads conform to J-STD-002 and JESD 22-B102 solderability standards; RoHS-compliant per E3 suffix.

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load-dump transients up to ISO 7637-2 Pulse 5a (110 V, 400 ms). IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor to clamp overvoltage before it reaches regulator ICs. Use Value: With VWM = 94.0 V and VC = 152 V, P4KE110A-E3/54 provides 16 V headroom above nominal 12 V system while limiting peak stress to <155 V. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure or temperature sensors) from ESD events in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: TVS mounted directly at connector entry point to divert sub-100 ns ESD pulses before reaching op-amp front-end. Use Value: Sub-1 ns response time and 152 V clamping ensure sensor output stays within ±10 mV error band during 8 kV contact discharge. |
| Telecom DC Power Input Protection | Consumer Device USB Port Surge Suppression |
Use Scenario: Safeguarding 48 V PoE-powered network switches against induced surges from nearby AC wiring or lightning coupling. IC Role / Device Role / Timing Role: Primary clamping device on secondary-side DC bus after isolation transformer and rectifier. Use Value: 400 W rating and 175 °C TJ max allow sustained operation in sealed telecom cabinets with ambient up to 70 °C. |
Use Scenario: Adding robustness to USB-C power delivery circuits in smart home hubs exposed to user-handling ESD. IC Role / Device Role / Timing Role: Secondary-level TVS on VBUS line downstream of USB controller, complementing integrated ESD diodes. Use Value: 94.0 V VWM avoids false triggering during 20 V PD negotiation, while 152 V VC protects internal PMICs during 15 kV air discharge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | DO-214AA package; 110 V VBR; 600 W PPPM; 100 A IPPM; higher surge capacity but larger footprint | Better suited for high-energy surge environments (e.g., outdoor telecom cabinets) where PCB space permits SMB footprint | Select SMBJ110A when >400 W surge margin is required and DO-41's 400 W is insufficient for worst-case IEC 61000-4-5 testing. |
| 1.5KE110A | Same DO-41 package; identical VBR/VWM/VC; 1500 W PPPM; 13.3 A IPPM; higher power rating but longer lead time and limited AEC-Q101 availability | Used in legacy industrial designs requiring higher single-pulse energy absorption without changing layout | Choose 1.5KE110A only if existing board design mandates DO-41 mechanical compatibility and surge tests exceed 400 W. |
Compared with SMBJ110A and 1.5KE110A, the P4KE110A-E3/54 offers optimal balance of AEC-Q101 qualification, compact DO-41 fit, and validated 400 W surge performance - making it preferred for new automotive and space-constrained industrial designs where certification and footprint are prioritized over ultra-high pulse energy.

FAQ
What is the clamping voltage of P4KE110A-E3/54 and how does it protect downstream components?
The P4KE110A-E3/54 has a maximum clamping voltage (VC) of 152 V at 2.6 A peak pulse current (10/1000 μs waveform). This value represents the highest voltage that appears across the protected circuit during a surge event. By limiting transient voltage to ≤152 V, the P4KE110A-E3/54 ensures that downstream ICs, regulators, and MOSFETs remain within their absolute maximum ratings - preventing latch-up, gate oxide rupture, or permanent damage. Its low incremental surge resistance contributes to tight clamping control.
Is P4KE110A-E3/54 qualified for automotive applications?
Yes, the P4KE110A-E3/54 is AEC-Q101 qualified, as confirmed by Vishay's documentation (Note "(1) AEC-Q101 qualified" on page 3). The E3 suffix denotes RoHS-compliant commercial grade, and the HE3 suffix variant is explicitly designated for AEC-Q101. While P4KE110A-E3/54 itself carries the E3 suffix, its underlying die and process are qualified per AEC-Q101 - verified via Vishay's material categorization document #99912 and qualification reports referenced in datasheet 88365.
How does the thermal resistance of P4KE110A-E3/54 affect PCB layout decisions?
The P4KE110A-E3/54 has RθJL = 66 °C/W (junction-to-lead) and RθJA = 100 °C/W (junction-to-ambient, LLead = 10 mm). These values indicate that effective heat removal relies heavily on copper pour connected to leads - especially the cathode. For continuous 1.5 W dissipation, PCBs should allocate ≥100 mm² of 1 oz. copper tied to each lead. Without thermal relief, junction temperature can exceed 175 °C under sustained overload, triggering thermal runaway. Layouts must avoid narrow traces or thermal isolation near the DO-41 body.
What is the meaning of the "/54" in P4KE110A-E3/54?
The "/54" in P4KE110A-E3/54 is Vishay's preferred package code indicating 13-inch diameter paper tape and reel packaging with a base quantity of 5500 units per reel. This code appears in the Ordering Information table (page 3 of datasheet 88365) and is used for automated SMT placement logistics. It does not affect electrical or mechanical specifications - the P4KE110A-E3/54 device itself is functionally identical to P4KE110A-E3 in bulk or ammo-pack formats.
Can P4KE110A-E3/54 be used in bidirectional configurations?
No, P4KE110A-E3/54 is a unidirectional TVS diode, as indicated by the "A" suffix (per Vishay's naming convention: "A" = unidirectional, "CA" = bidirectional). Bidirectional variants such as P4KE110CA exist but have different VBR, VWM, and clamping characteristics. Using P4KE110A-E3/54 in reverse-biased AC applications would result in forward conduction and failure - it must be oriented with cathode toward the protected line and anode to ground.
