Product details
Overview
5KP36A-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal paths. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR) at 5.0 mA, 5000 W peak pulse power (10/1000 μs), and clamps transients to ≤58.1 V at 86.1 A. It is used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the 5KP36A-E3/73 datasheet, 5KP36A-E3/73 pinout, 5KP36A-E3/73 application, or 5KP36A-E3/73 equivalent, key selection criteria include clamping voltage margin vs. protected device VDS/VCC, unidirectional polarity requirement, P600 package thermal limits, and AEC-Q101 qualification for automotive under-hood use.
Technical Context
This TVS operates as a voltage-clamping overvoltage protection device, triggered when reverse voltage exceeds its breakdown threshold (VBR). Its glass-passivated P600 junction enables low incremental surge resistance and sub-nanosecond response time, ensuring fast suppression of lightning- and switching-induced transients.
It is rated for 5000 W peak pulse power (10/1000 μs waveform, 0.01% duty cycle), with derating above 25 °C per Fig. 2, and supports 600 A non-repetitive forward surge current (8.3 ms half-sine). The device is RoHS-compliant (E3 suffix), JESD201 Class 1A whisker-tested, and UL 94 V-0 molded.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 40.0 V / 44.2 V at 5.0 mA - Ensures reliable turn-on margin above VWM with 5% tolerance |
| VC @ IPPM | ≤58.1 V at 86.1 A - Clamping voltage defines maximum stress on downstream components |
| PPPM | 5000 W (10/1000 μs) - Withstands high-energy surges without failure; requires heatsinking above 25 °C |
| IFSM | 600 A (8.3 ms half-sine) - Supports single-event overcurrent events like load dump |
| TJ range | –55 °C to +175 °C - Enables operation in under-hood automotive and industrial environments |
| Package | P600 - Axial-leaded, 9.5 mm body length, UL 94 V-0 epoxy, suitable for through-hole PCB mounting |
Pinout & Package
The 5KP36A-E3/73 is a two-terminal axial-leaded device in the P600 package. The cathode is marked by a color band on the body; the anode is the unmarked lead. No internal pin numbering applies - terminals are functionally defined as Anode and Cathode only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to ground or low-side return path; establishes reference for clamping action |
| Cathode | Clamping output / Surge sink node | Connected to protected line (e.g., 36 V rail); conducts surge current to ground during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including temperature cycling, humidity, and mechanical shock |
| 5000 W peak pulse rating | Provides robust protection against ISO 7637-2 Pulse 5a (load dump) and IEC 61000-4-5 Level 4 surges |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage margin needed between protected IC's absolute max rating and VBR |
| Matte tin-plated leads | Ensures solderability per J-STD-002 and JESD 22-B102, compatible with lead-free reflow and wave processes |
| UL 94 V-0 molding compound | Prevents flame propagation in high-power fault conditions, meeting safety standards for industrial equipment |

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 | Lower peak power (400 W), SMA package (surface-mount), 36 V VWM, 58.1 V VC at 6.9 A | Not suitable for 5 kA-level surges; limited to board-level ESD and low-energy transients | Select when space-constrained PCB layout demands SMT and surge energy is <100 mJ |
| ON Semiconductor 1.5KE36A | Same 36 V VWM, but lower PPPM (1500 W), DO-201 package, 58.1 V VC at 25.8 A | Lacks AEC-Q101 qualification; not recommended for automotive under-hood deployment | Choose for cost-sensitive industrial controls where AEC-Q101 is not mandated |
Compared with SMAJ36A and 1.5KE36A, the 5KP36A-E3/73 delivers 3.3× higher surge capacity than 1.5KE36A and 12.5× more than SMAJ36A, while providing automotive-grade reliability and thermal robustness in the P600 through-hole package.

FAQ
What is the clamping voltage of the 5KP36A-E3/73 under maximum rated surge current?
The 5KP36A-E3/73 clamps to a maximum of 58.1 V when subjected to its rated peak pulse current of 86.1 A (10/1000 μs waveform). This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during a surge event. The 5KP36A-E3/73 maintains this clamping performance across its full operating temperature range when properly mounted.
Is the 5KP36A-E3/73 suitable for automotive applications?
Yes, the 5KP36A-E3/73 is AEC-Q101 qualified and rated for junction temperatures from –55 °C to +175 °C, making it suitable for under-hood automotive applications such as engine control units, body control modules, and ADAS power supplies. Its P600 package provides mechanical robustness and thermal mass required for sustained surge handling in harsh environments. The 5KP36A-E3/73 meets automotive load dump immunity requirements per ISO 7637-2.
What does the "E3/73" suffix indicate in 5KP36A-E3/73?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads and JESD201 Class 1A whisker resistance. The "/73" indicates packaging in 73" diameter tape-and-reel format with 800 units per reel. This differs from /54 (13" reel) and confirms the 5KP36A-E3/73 is supplied in industry-standard automated assembly packaging. The 5KP36A-E3/73 retains all electrical and thermal specifications regardless of reel size.
How does the 5KP36A-E3/73 compare to bidirectional TVS diodes?
The 5KP36A-E3/73 is unidirectional only, meaning it protects against positive transients on the cathode side relative to anode (ground), and blocks normal forward voltage. Bidirectional variants (e.g., 5KP36CA) would conduct in both directions and are used for AC line or data-line protection. For 36 V DC rail protection, the 5KP36A-E3/73 offers lower leakage and tighter VBR tolerance than bidirectional equivalents. The 5KP36A-E3/73 is not interchangeable with CA-suffixed parts without circuit redesign.
Can the 5KP36A-E3/73 be used in parallel for higher surge current handling?
No - the 5KP36A-E3/73 should not be paralleled without external current-sharing resistors or matched dynamic impedance, as minor VBR variations (±5%) cause uneven current division and potential thermal runaway. Vishay specifies single-device operation only. For higher surge ratings, select a higher-voltage 5KP part with lower IPPM (e.g., 5KP40A) or consult Vishay's application note AN1002 for derating guidance. The 5KP36A-E3/73 is validated for standalone use per datasheet conditions.
