Product details
Overview
P4KE13HE3/54 from Vishay General Semiconductor is an AEC-Q101-qualified unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 13.7 V maximum breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 18.2 V clamping voltage (VC) at 22.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P4KE13HE3/54 datasheet, P4KE13HE3/54 pinout, P4KE13HE3/54 application, or P4KE13HE3/54 equivalent, this device is selected for automotive-grade overvoltage protection on power rails and signal lines where AEC-Q101 qualification, low clamping ratio, and robust surge handling are required.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (12.4–13.7 V), it avalanches to limit transient energy across protected circuit nodes. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1 ns), critical for safeguarding MOSFET gates and microcontroller I/O pins.
Thermal performance is defined by RθJL = 66 °C/W and RθJA = 100 °C/W, supporting operation up to +175 °C junction temperature. The device complies with JESD 201 Class 2 whisker testing and UL 94 V-0 flammability requirements, confirming suitability for high-reliability automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V - defines precise avalanche initiation window for reliable overvoltage triggering without false trips |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage rises above 1.0 μA |
| VC @ IPPM | 18.2 V at 22.0 A - clamping voltage during 10/1000 μs surge, limiting stress on downstream ICs |
| PPPM | 400 W - peak transient power dissipation capability, enabling protection against IEC 61000-4-5 Level 3 surges |
| IFSM | 40 A - non-repetitive forward surge current rating, supporting inrush tolerance in DC power inputs |
| TJ max. | +175 °C - extended junction temperature range enables under-hood automotive deployment |
| Package | DO-41 (DO-204AL) - industry-standard axial leaded package with 0.205" body diameter and 0.034" lead diameter |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; cathode indicated by color band on one end. Leads conform to J-STD-002 and JESD 22-B102 solderability standards. Maximum solder dip: 275 °C for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path / low-impedance return during clamping | Connected to ground or low-side reference; carries full surge current during transient events |
| Cathode | Reverse-biased terminal / clamping node | Connected to protected line (e.g., 12 V rail); avalanches when voltage exceeds VBR, shunting surge to ground |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics per stress test requirements |
| Glass passivated junction | Ensures stable VBR tolerance (±5 %) and low leakage drift over temperature and lifetime |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Surface-mount SMB package (3.5 mm × 4.6 mm), 600 W PPPM, VC = 21.5 V @ 24.9 A | Requires PCB redesign; better suited for high-density layouts and automated assembly | Select SMBJ13A when space-constrained designs demand SMT placement and higher surge margin is acceptable |
| 1.5KE13A | Same DO-41 package but 1500 W PPPM, VC = 21.2 V @ 70.8 A, no AEC-Q101 qualification | Lacks automotive qualification; used in industrial/commercial power supplies where qualification is not mandated | Choose 1.5KE13A only for cost-sensitive non-automotive applications requiring higher single-pulse energy absorption |
Compared with SMBJ13A and 1.5KE13A, P4KE13HE3/54 uniquely combines AEC-Q101 qualification, DO-41 through-hole compatibility, and optimized 400 W/18.2 V clamping for automotive and industrial retrofit scenarios where reliability and serviceability are prioritized over footprint size or extreme surge capacity.

FAQ
What is the breakdown voltage tolerance for P4KE13HE3/54?
The P4KE13HE3/54 has a specified breakdown voltage range of 12.4 V to 13.7 V at 1.0 mA test current, representing a ±5 % tolerance around the nominal 13 V rating. This tight VBR window ensures consistent clamping behavior across production lots and temperature ranges, critical for predictable protection in automotive power systems.
Is P4KE13HE3/54 suitable for bidirectional transient protection?
No, P4KE13HE3/54 is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the P4KE13CA variant. Using P4KE13HE3/54 in AC-coupled or symmetrical surge environments would result in forward conduction during negative half-cycles, potentially damaging the device or failing to suppress transients.
What does the "HE3/54" suffix indicate in P4KE13HE3/54?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies packaging in 13-inch paper tape and reel with 5500 units per reel. This distinguishes P4KE13HE3/54 from commercial-grade P4KE13A-E3/54 (non-AEC-Q101) and bare lead variants.
How does P4KE13HE3/54 perform under elevated ambient temperatures?
P4KE13HE3/54 derates linearly above 25 °C ambient: its 400 W peak pulse power drops to ~200 W at 100 °C case temperature per Figure 2 in the datasheet. Its +175 °C maximum junction temperature and 66 °C/W junction-to-lead thermal resistance allow sustained operation in under-hood automotive locations when mounted with adequate copper pour and lead length.
Can P4KE13HE3/54 replace P4KE13A in existing designs?
Yes, P4KE13HE3/54 is a direct functional and mechanical replacement for P4KE13A, sharing identical electrical specs, DO-41 package, and pinout. The "HE3" version adds AEC-Q101 qualification and enhanced whisker resistance-making it suitable for automotive upgrades without layout or schematic changes, provided qualification compliance is required.
