Product details
Overview
5KP36-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping on power rails and signal lines. It features 5000 W peak pulse power (10/1000 μs), 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR at 5.0 mA), and clamps to ≤58.1 V at 86.1 A peak pulse current - used to protect MOSFETs, ICs, and sensor interfaces in automotive power supplies.
For engineers reviewing the 5KP36-E3/54 datasheet, 5KP36-E3/54 pinout, 5KP36-E3/54 application, or 5KP36-E3/54 equivalent, this page delivers verified electrical specs, thermal derating behavior, AEC-Q101 qualification status, RoHS compliance (E3 suffix), and real-world clamping performance under repetitive transients - critical for industrial power supply overvoltage protection and automotive ECU design.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp with glass-passivated P600 junction, optimized for fast response (<1 ns) and low incremental surge resistance. Its 175 °C maximum junction temperature and 8.0 W steady-state power dissipation support operation in thermally constrained environments when mounted on adequate heatsink area.
The device meets JEDEC registered electrical characteristics per ANSI/IEEE C62.35, with 0.104 %/°C temperature coefficient of VBR, 2.0 μA max reverse leakage at VWM, and 3.5 V forward voltage at 100 A - enabling reliable crowbar replacement in switching power supply output stages without latch-up risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before clamping begins; sets safe margin below system nominal rail (e.g., 36 V for 42 V automotive systems) |
| VBR (min/max) | 40.0 V / 44.2 V at 5.0 mA - defines precise avalanche onset range; ensures consistent triggering across production lots |
| VC @ IPPM | ≤58.1 V at 86.1 A - clamped voltage during 10/1000 μs surge; limits downstream component stress to safe levels |
| PPPM | 5000 W - peak pulse power handling capability; sustains high-energy lightning or load-dump transients without failure |
| TJ max | 175 °C - enables operation in under-hood automotive environments and industrial enclosures without thermal shutdown |
| IFSM | 600 A - non-repetitive forward surge rating (8.3 ms half-sine); supports fault-current withstand during short-circuit events |
| Leakage @ VWM | ≤2.0 μA - negligible standby power loss; avoids battery drain in always-on automotive modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ36A | DO-214AC package; 400 W peak power; 36 V VWM; 58.1 V VC @ 6.8 A | Lower surge capacity; suited for board-level signal-line protection, not main power rail clamping | Select when space-constrained PCB layout requires SMD mounting and surge energy is ≤400 W |
| ON Semiconductor 1.5KE36A | DO-201AD package; 1500 W peak power; same VWM/VC but 25.5 A IPPM | Limited to medium-energy transients; lacks AEC-Q101 qualification and P600 thermal mass | Choose for cost-sensitive industrial controls where automotive qualification and 5 kW rating are unnecessary |
Compared with SMAJ36A and 1.5KE36A, the 5KP36-E3/54 delivers 3.3× and 3.3× higher peak pulse power respectively, plus AEC-Q101 validation and P600 thermal robustness - making it the only option among the three qualified for under-hood automotive load-dump protection.

FAQ
What is the maximum clamping voltage of the 5KP36-E3/54 under a 10/1000 μs surge?
The 5KP36-E3/54 clamps to a maximum of 58.1 V when subjected to its rated 86.1 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is guaranteed per JEDEC test conditions and represents the upper limit of voltage seen by downstream circuitry during worst-case surge events - critical for ensuring compatibility with 60 V-rated components in 36 V systems.
Is the 5KP36-E3/54 qualified for automotive applications?
Yes, the 5KP36-E3/54 carries the E3 suffix indicating RoHS compliance and commercial-grade qualification. While the base E3 variant is not AEC-Q101 certified, the HE3 variant (e.g., 5KP36HE3/54) is explicitly AEC-Q101 qualified per the Vishay datasheet. For automotive use, specify the HE3 version to ensure full qualification for under-hood environments.
What does the "/54" suffix mean in 5KP36-E3/54?
The "/54" suffix in 5KP36-E3/54 denotes the preferred package code per Vishay's ordering nomenclature, specifying 13-inch diameter paper tape and reel packaging with a base quantity of 800 devices per reel. It has no effect on electrical or thermal specifications - only on logistics and assembly handling.
Can the 5KP36-E3/54 replace a 1.5KE36A in an existing design?
No direct drop-in replacement is recommended. Although both share 36 V VWM, the 5KP36-E3/54 has 5000 W peak power and P600 through-hole package, whereas the 1.5KE36A offers only 1500 W and uses DO-201AD. Substituting requires PCB footprint change, thermal redesign, and verification of surge energy margins - especially for automotive load-dump scenarios where 5KP36-E3/54's higher rating is essential.
What is the reverse leakage current of the 5KP36-E3/54 at its stand-off voltage?
The 5KP36-E3/54 exhibits a maximum reverse leakage current (ID) of 2.0 μA at its 36 V stand-off voltage (VWM) and 25 °C ambient temperature. This ultra-low leakage ensures minimal power loss in always-on automotive modules and avoids false triggering in high-impedance sensor bias networks - confirmed in the Vishay 88308 datasheet Table "ELECTRICAL CHARACTERISTICS".
