Product details
Overview
P4KE11HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit-level ESD and surge protection. It features 11.6 V maximum breakdown voltage (VBR), 9.40 V stand-off voltage (VWM), 15.6 V clamping voltage at 25.6 A peak pulse current, 400 W peak pulse power rating (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P4KE11HE3/54 datasheet, P4KE11HE3/54 pinout, P4KE11HE3/54 application, or P4KE11HE3/54 equivalent, this device is selected for robust overvoltage protection on DC power rails and low-speed signal lines where fast response (<1 ns), low clamping ratio (1.66×VWM), and stable thermal performance up to 175 °C junction temperature are required.
Technical Context
This TVS operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to transients and stable clamping under repetitive 0.01% duty cycle pulses. Its unidirectional polarity-marked by cathode band-supports DC-biased protection paths without reverse conduction during normal operation.
The device delivers 400 W peak pulse power per 10/1000 μs waveform, with 1.5 W steady-state power dissipation on infinite heatsink and 40 A non-repetitive forward surge capability (8.3 ms half-sine). Thermal resistance is 66 °C/W junction-to-lead, supporting reliable operation in compact PCB layouts with minimal copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (max) | 11.6 V - Ensures reliable avalanche conduction above system operating voltage without premature triggering |
| VWM | 9.40 V - Maximum continuous reverse working voltage; sets upper limit for safe DC bias operation |
| VC @ IPPM | 15.6 V - Clamping voltage at 25.6 A peak pulse; defines worst-case voltage seen by protected IC during surge |
| PPPM | 400 W - Peak pulse power handling for 10/1000 μs waveform; determines survivability against lightning/inductive spikes |
| TJ max | 175 °C - Maximum junction temperature; enables use in under-hood automotive or high-ambient industrial environments |
| IFSM | 40 A - Non-repetitive forward surge rating (8.3 ms); supports protection of downstream rectifiers or MOSFETs |
| RθJL | 66 °C/W - Junction-to-lead thermal resistance; informs heatsinking requirements for sustained pulse repetition |
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. Cathode indicated by color band; anode is unmarked lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked lead) | Forward current entry / transient return path | Connected to ground or low-impedance return node in unidirectional clamp configuration |
| Cathode (banded lead) | Reverse-biased protection node | Connected to protected line (e.g., +12 V rail); conducts avalanche current when VLINE exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, low-leakage (5.0 μA max at VWM) avalanche behavior across -55 °C to +175 °C |
| AEC-Q101 qualified | Validated for automotive applications including engine control units, body electronics, and infotainment power rails |
| 400 W peak pulse power (10/1000 μs) | Withstands ISO 7637-2 Pulse 1 (inductive switch-off) and IEC 61000-4-5 Level 3 surges without degradation |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD contact discharge >15 kV) |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance; suitable for high-reliability solder reflow and long-life deployments |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply lines in engine control modules from load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS clamping transient energy before it reaches MCU power pins or LDO inputs. Use Value: Limits clamped voltage to 15.6 V during 25.6 A surge, preventing latch-up or permanent damage to 16 V-rated components. |
Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA loop drivers) in factory automation sensors. IC Role / Device Role / Timing Role: Fast-response shunt element absorbing ESD events from cable coupling or human contact. Use Value: Sub-1 ns response ensures clamping occurs before sensitive op-amps or ADC references exceed absolute maximum ratings. |
| Consumer Device USB Port Protection | Telecom Line Card Surge Suppression |
Use Scenario: Secondary-level protection on VBUS line of USB 2.0 host ports in set-top boxes and smart displays. IC Role / Device Role / Timing Role: Standby-mode suppressor holding off 9.4 V nominal bus while clamping 15 kV HBM ESD events. Use Value: 5.0 μA max leakage at 9.4 V avoids loading USB suspend current budget; DO-41 allows manual rework on legacy designs. |
Use Scenario: Front-end protection on low-voltage DC feeds powering remote PHY devices in DSLAM line cards. IC Role / Device Role / Timing Role: Primary surge limiter on -48 V telecom supply, coordinated with upstream GDTs for staged protection. Use Value: 175 °C max junction temperature supports operation in sealed, fanless enclosures with ambient up to 85 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | DO-214AA package; 10 V VWM, 17.0 V VC @ 23.5 A; 600 W PPPM | Surface-mount footprint; higher clamping voltage but greater power handling | Select SMBJ10A when board space is constrained and SMT assembly is preferred; verify layout thermal relief for 66 °C/W RθJA. |
| P4KE10HE3/54 | Lower VBR range (9.5–10.5 V); 8.55 V VWM; 14.5 V VC @ 27.6 A | Narrower margin between VWM and typical 12 V rail; tighter clamping but higher risk of leakage at elevated temperature | Choose P4KE10HE3/54 only if system VDC is tightly regulated ≤10.5 V and leakage <1 μA at 85 °C is critical. |
Compared with P4KE10HE3/54, the P4KE11HE3/54 offers higher VWM margin for 12 V systems and lower temperature coefficient (0.075 %/°C vs. 0.073 %/°C), while SMBJ10A trades axial-leaded serviceability for higher surge capacity and automated assembly compatibility.

FAQ
What is the maximum clamping voltage of the P4KE11HE3/54 under rated surge conditions?
The P4KE11HE3/54 has a maximum clamping voltage (VC) of 15.6 V at its rated peak pulse current (IPPM) of 25.6 A, measured using the standard 10/1000 μs waveform. This value is guaranteed per Vishay document 88365 and defines the upper voltage limit imposed on protected circuitry during transient events. The P4KE11HE3/54 maintains this clamping performance across its full operating temperature range.
Is the P4KE11HE3/54 suitable for automotive applications?
Yes, the P4KE11HE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, glass-passivated junction, and HE3 suffix (JESD 201 Class 2 whisker resistance) meet stringent automotive reliability requirements. The P4KE11HE3/54 is commonly deployed in engine control units, body control modules, and infotainment power supplies.
How does the P4KE11HE3/54 differ from the P4KE11A variant?
The P4KE11HE3/54 is the AEC-Q101 qualified, RoHS-compliant version with HE3 suffix, whereas P4KE11A is the commercial-grade variant. Both share identical electrical characteristics (VBR, VWM, VC, PPPM), but the P4KE11HE3/54 undergoes additional stress testing per AEC-Q101 and uses whisker-resistant plating. The P4KE11HE3/54 is the recommended choice for automotive and industrial applications requiring certified reliability.
What is the reverse leakage current specification for the P4KE11HE3/54 at its stand-off voltage?
At its 9.40 V stand-off voltage (VWM) and 25 °C ambient temperature, the P4KE11HE3/54 exhibits a maximum reverse leakage current (ID) of 5.0 μA. This low leakage ensures minimal power loss in standby mode and avoids interference with high-impedance sensing circuits. Leakage remains within specification up to 85 °C, with gradual increase governed by the device's temperature coefficient.
Can the P4KE11HE3/54 be used in bidirectional configurations?
No, the P4KE11HE3/54 is a unidirectional TVS diode, identified by its cathode band marking. Bidirectional operation requires a CA-suffixed part such as P4KE11CA. Using the P4KE11HE3/54 in reverse-biased AC applications would result in forward conduction and potential failure. For bidirectional protection, select the correctly designated variant-not the P4KE11HE3/54.
