Product details
Overview
5KP36-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on DC 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 transients to ≤58.1 V at 86.1 A peak pulse current - used in automotive power supply output protection and industrial sensor interface circuits.
For engineers reviewing the 5KP36-E3/73 datasheet, 5KP36-E3/73 pinout, 5KP36-E3/73 application, or 5KP36-E3/73 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, low incremental surge resistance, and compatibility with 275 °C solder dip per JESD 22-B106 - critical for reliability in automotive and industrial overvoltage environments.
Technical Context
This TVS diode operates as a voltage-clamping device in parallel with protected circuitry, entering avalanche conduction when reverse voltage exceeds VBR. Its P600 glass-passivated chip junction enables fast response time (<1 ns) and stable clamping under repetitive 0.01% duty cycle surges.
It is rated for 5000 W peak pulse power (10/1000 μs waveform), 8.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C, and withstands 500 A non-repetitive forward surge current (8.3 ms half-sine). The cathode is marked by a color band on the molded epoxy body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 40.0 V / 44.2 V at 5.0 mA - ensures reliable avalanche initiation within tight tolerance for predictable protection threshold |
| VC @ IPPM | ≤58.1 V at 86.1 A - defines worst-case clamped voltage seen by downstream ICs during surge |
| PPPM | 5000 W - supports high-energy transients such as load dump or inductive switching without failure |
| TJ max | +175 °C - enables operation in under-hood automotive and high-temperature industrial environments |
| Polarity | Unidirectional - protects against reverse-polarity transients only; requires correct orientation in circuit |
| Package | P600 - axial-leaded, RoHS-compliant molded epoxy case meeting UL 94 V-0 flammability rating |
Pinout & Package
P600 package: axial-leaded, molded epoxy body with cathode indicated by color band. Matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards. Solder dip rated up to 275 °C for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lower potential node; completes clamping path during reverse surge |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., +12 V rail); color band identifies this end for correct PCB placement |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical stress testing |
| 5000 W peak pulse power | Withstands severe transients like ISO 7637-2 Pulse 5a (load dump) without degradation |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for sensitive ICs |
| Fast response time | Sub-nanosecond turn-on ensures clamping occurs before downstream MOSFETs or controllers are damaged |
| UL 94 V-0 molding compound | Self-extinguishing encapsulation prevents fire propagation in fault conditions |
Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump transients (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed across input rail, conducting only during overvoltage events. Use Value: Limits rail voltage to ≤58.1 V during 5000 W surges, preventing damage to LDOs, microcontrollers, and CAN transceivers. | Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and inductive coupling in factory automation systems. IC Role / Device Role / Timing Role: Parallel-connected transient shunt on signal line, activated within nanoseconds of voltage excursion. Use Value: Clamps fast ESD pulses (IEC 61000-4-2) to safe levels while maintaining signal integrity due to low capacitance and leakage (<2 μA at 36 V). |
| Switching Power Supply Output Clamp | Telecom DC Feeder Protection |
Use Scenario: Replacing crowbar circuits on 36 V output of telecom DC-DC converters to avoid permanent shutdown during overvoltage. IC Role / Device Role / Timing Role: Self-resetting overvoltage clamp that conducts only during fault, allowing system recovery after fuse/breaker reset. Use Value: Enables automatic resumption of operation post-transient, unlike SCR-based crowbars requiring manual intervention. | Use Scenario: Safeguarding central office power feeders (−48 V DC) against lightning-induced surges on outside plant wiring. IC Role / Device Role / Timing Role: Primary surge suppression stage mounted at equipment entry point, upstream of secondary protectors. Use Value: Absorbs multi-kW surges with minimal voltage rise, preserving uptime of VoIP gateways and DSLAM line cards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A-E3/52 | Lower peak pulse power (600 W), smaller SMB package, same VWM (36 V) and VC (58.1 V) | Targeted at board-level signal-line protection rather than bulk power rail clamping | Select when space-constrained layouts or lower-energy transients (e.g., IEC 61000-4-5 Level 3) apply |
| 1.5KE36A | Same P600 package and 36 V VWM, but lower PPPM (1500 W) and higher VC (60.0 V) | Legacy design with reduced surge margin; not AEC-Q101 qualified | Acceptable for cost-sensitive industrial use where automotive qualification is unnecessary |
Compared with SMBJ36A-E3/52 and 1.5KE36A, the 5KP36-E3/73 delivers 3.3× higher surge energy handling and automotive-grade validation - essential for protecting high-current power domains where single-event robustness directly impacts field failure rates.

FAQ
What is the maximum clamping voltage of the 5KP36-E3/73 under surge conditions?
The 5KP36-E3/73 has a maximum clamping voltage (VC) of 58.1 V when subjected to its rated peak pulse current of 86.1 A (10/1000 μs waveform). This value is measured at the device terminals and represents the worst-case voltage imposed on protected circuitry during a full-rated transient event - critical for verifying safe operating margins of downstream components like microcontrollers or power MOSFETs.
Is the 5KP36-E3/73 suitable for automotive applications?
Yes, the 5KP36-E3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, robust P600 package, and ability to withstand load dump transients (ISO 7637-2 Pulse 5a) make it appropriate for engine control units, body control modules, and ADAS power supplies - provided layout follows Vishay's recommended thermal mounting guidelines.
Does the 5KP36-E3/73 have bidirectional polarity?
No, the 5KP36-E3/73 is unidirectional only, as confirmed in the Vishay datasheet. It conducts during reverse-biased overvoltage events and blocks forward current up to its specified IFSM. For AC or bipolar transient protection, a separate bidirectional TVS (e.g., 5KP36CA) or back-to-back configuration would be required - the 5KP36-E3/73 must be oriented with its cathode toward the protected line.
What is the standoff voltage (VWM) and why does it matter for the 5KP36-E3/73?
The 5KP36-E3/73 has a standoff voltage (VWM) of 36 V - the maximum continuous DC or RMS voltage it can block without significant leakage. This parameter ensures the device remains non-conductive during normal operation, minimizing power loss and avoiding false triggering. Selecting VWM ≥110% of nominal system voltage (e.g., 36 V for a 33 V rail) prevents premature conduction while retaining sufficient margin for transients.
How does the P600 package of the 5KP36-E3/73 support thermal management?
The P600 package of the 5KP36-E3/73 features axial leads and a molded epoxy body optimized for high-power dissipation. With 8.0 W power dissipation capability on an infinite heatsink at 75 °C lead temperature, it relies on PCB copper area and lead length for heat spreading. Vishay recommends ≥10 mm² of 2 oz copper per lead and minimum 8 mm lead length to achieve rated derating - critical for sustaining repeated surge events without thermal runaway.
