Product details
Overview
P6KE110HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of 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 3.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE110HE3/54 datasheet, P6KE110HE3/54 pinout, P6KE110HE3/54 application, or P6KE110HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, low incremental surge resistance, fast response time, and compatibility with 13" paper tape & reel delivery for automated SMT assembly.
Technical Context
The P6KE110HE3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering precise bi-polar clamping behavior only in reverse-biased mode (uni-directional polarity). Its thermal resistance is 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient), enabling reliable operation under transient surges up to 100 A IFSM (8.3 ms half-sine).
It exhibits a 0.107 %/°C temperature coefficient of VBR, ensuring stable breakdown voltage across -55 °C to +175 °C operating range. The device meets UL 497B recognition (QVGQ2) and complies with JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 2 whisker testing due to its HE3 suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1.0 mA test current - defines guaranteed avalanche initiation window for predictable clamping onset |
| VWM | 94.0 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 152 V at 3.9 A (10/1000 µs) - peak clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 600 W - surge energy handling capacity per single 10/1000 µs pulse, derated above 25 °C ambient |
| IFSM | 100 A - non-repetitive forward surge current rating (8.3 ms half-sine), critical for input rectifier-stage protection |
| TJ max | +175 °C - enables use in under-hood automotive and high-temperature industrial environments without thermal shutdown |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance supports efficient heat transfer to PCB copper pour or heatsinked lead |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case with matte tin-plated leads. Cathode indicated by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during forward surge events up to 100 A |
| Cathode | Avalanche clamping terminal | Connected to protected line (e.g., 12 V rail); initiates avalanche breakdown when reverse voltage exceeds 105 V |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per stress test plan |
| Glass passivated junction | Ensures stable VBR tolerance and long-term leakage stability vs. metallization degradation or moisture ingress |
| 600 W peak pulse power (10/1000 µs) | Withstands EN 61000-4-5 Level 4 (4 kV) surge events on 50 Ω source impedance without degradation |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on downstream components - e.g., keeps 12 V rail below 152 V during transients |
| UL 497B recognized (QVGQ2) | Approved for use in telecom and industrial signal-line protectors without additional system-level certification burden |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: 12 V battery-fed ECU power input subjected to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Primary shunt clamp placed upstream of DC/DC converter input to limit transient voltage to <152 V. Use Value: Prevents destruction of input MOSFETs and controller ICs during 120 V/200 ms load dump events. |
Use Scenario: 4–20 mA current loop interface exposed to field wiring induced surges in factory automation. IC Role / Device Role / Timing Role: Uni-directional TVS connected between loop+ and ground to clamp reverse polarity and surge transients. Use Value: Maintains loop integrity by limiting voltage across transmitter IC to ≤152 V during 1 kV/500 Ω surge (IEC 61000-4-5). |
| Consumer PSU DC Output Protection | Telecom Line Card Surge Suppression |
|
Use Scenario: +5 V and +3.3 V outputs of AC/DC adapter subject to capacitive discharge and ESD coupling. IC Role / Device Role / Timing Role: Secondary-side TVS mounted directly at connector to suppress fast-rising transients before reaching load ICs. Use Value: Clamps sub-100 ns ESD events to <152 V, protecting USB PHYs and PMICs without adding capacitance to regulated rail. |
Use Scenario: TIP/RING lines of VoIP gateway exposed to lightning-induced surges on PSTN trunk lines. IC Role / Device Role / Timing Role: Paired uni-directional TVS devices (P6KE110HE3/54 + P6KE110A) used in series with gas discharge tube for hybrid protection. Use Value: Provides low-clamp, fast-response stage that handles initial surge rise time before GDT fires, reducing let-through voltage. |
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-E3/52 (Vishay) | Same VBR (105–116 V) but SMB package (surface-mount), 600 W rating, lower IPPM (3.7 A), higher VC (179 V) | Requires PCB re-layout; better suited for space-constrained board-level designs vs. through-hole legacy systems | Select when automated SMT assembly and smaller footprint are prioritized over lead-forming flexibility |
| 1.5KE110A (ON Semiconductor) | Same DO-204AC package, identical VBR/VWM/VC specs, but commercial-grade only (not AEC-Q101 qualified), no HE3 whisker rating | Lacks automotive qualification and enhanced plating; suitable for industrial/commercial but not automotive OEM designs | Select for cost-sensitive non-automotive applications where AEC-Q101 and JESD 201 Class 2 are not required |
Compared with SMBJ110A-E3/52 and 1.5KE110A, the P6KE110HE3/54 uniquely combines AEC-Q101 qualification, DO-204AC through-hole compatibility, and JESD 201 Class 2 whisker resistance - making it the preferred choice for automotive Tier-1 suppliers requiring traceable, high-reliability through-hole TVS devices.

FAQ
What does the 'HE3' suffix indicate in P6KE110HE3/54?
The 'HE3' suffix in P6KE110HE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. This distinguishes it from standard 'E3' variants (commercial grade only) and confirms suitability for automotive applications requiring extended reliability validation and enhanced lead finish durability under thermal cycling.
Is P6KE110HE3/54 uni-directional or bi-directional?
P6KE110HE3/54 is a uni-directional TVS diode, as confirmed by its part number ending in 'A' (not 'CA') and specification of forward voltage (VF = 5.0 V at 50 A). It protects against reverse-polarity connection and positive-going transients on DC lines, with cathode marked by a color band on the DO-204AC package body.
What is the clamping voltage of P6KE110HE3/54 and how is it measured?
The clamping voltage of P6KE110HE3/54 is 152 V, measured at 3.9 A peak pulse current using a 10/1000 µs waveform per IEC 61000-4-5. This value represents the maximum voltage imposed on the protected circuit during standardized surge testing and is validated per Figure 1 and Table on page 2 of Vishay document 88369.
Can P6KE110HE3/54 be used in place of P6KE110A?
Yes - P6KE110HE3/54 is a direct replacement for P6KE110A with identical electrical specifications (VBR, VWM, VC, PPPM), same DO-204AC package, and compatible pinout. The 'HE3' version adds AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, making it suitable for automotive use where P6KE110A is limited to commercial applications.
What is the maximum operating temperature for P6KE110HE3/54?
The maximum operating junction temperature for P6KE110HE3/54 is +175 °C, as specified in the Thermal Characteristics table of Vishay document 88369. This allows deployment in high-temperature environments such as engine control units, motor drives, and industrial power converters without thermal derating concerns up to rated power limits.
