Product details
Overview
5KP150AHE3_A/C from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection. It features 150 V stand-off voltage (VWM), 167–185 V breakdown voltage (VBR), 5000 W peak pulse power (10/1000 μs), 243 V clamping voltage at 20.6 A, and AEC-Q101 qualification - used to protect automotive power supplies and industrial sensor signal lines against lightning and inductive switching transients.
For engineers reviewing the 5KP150AHE3_A/C datasheet, 5KP150AHE3_A/C pinout, 5KP150AHE3_A/C application, or 5KP150AHE3_A/C equivalent, key selection criteria include clamping performance under 10/1000 μs surges, unidirectional polarity requirement, P600 thermal derating behavior, AEC-Q101 compliance for automotive use, and compatibility with 13" tape-and-reel automated assembly.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device during overvoltage events, leveraging a glass-passivated P600 chip junction for low incremental surge resistance and fast response. Its unidirectional structure enables reverse-biased clamping only, with 3.5 V forward voltage at 100 A and 500 A non-repetitive surge current rating.
The device is thermally rated for TJ = −55 °C to +175 °C, with power dissipation derated linearly above TA = 25 °C and lead temperature (TL) limited to 75 °C for 8.0 W continuous operation. It meets JESD 201 class 2 whisker testing (HE3 suffix) and UL 94 V-0 flammability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 150 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 167 V / 185 V at 5 mA - ensures reliable breakdown within defined tolerance band |
| VC @ IPPM | 243 V at 20.6 A - clamping voltage limits downstream component stress during 10/1000 μs surge |

Applications
| Automotive Power Supply Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs and ADAS modules from load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed across input rails to clamp surges >150 V while maintaining normal operation below VWM. Use Value: Clamps to 243 V at 20.6 A, limiting stress on upstream fuses and downstream DC-DC converters during ISO 7637-2 Pulse 5a events. | Use Scenario: Shielding analog outputs (e.g., 4–20 mA, 0–10 V) of pressure/temperature sensors in factory automation systems. IC Role / Device Role / Timing Role: Low-leakage (≤2 μA at 150 V) TVS mounted at connector interface to absorb ESD and cable discharge events. Use Value: 243 V clamping prevents latch-up or damage to precision op-amps and ADC front-ends during field-induced transients. |
| Telecom DC Power Feeds | Switching Power Supply Output Clamping |
Use Scenario: Safeguarding -48 V telecom rectifier outputs against lightning-induced surges on outdoor plant wiring. IC Role / Device Role / Timing Role: Reverse-connected across output to clamp positive-going transients relative to return; leverages unidirectional architecture. Use Value: Withstands 5000 W pulses and maintains <2 μA leakage at −48 V, preserving system efficiency and isolation integrity. | Use Scenario: Replacing crowbar circuits on 12–48 V SMPS outputs to avoid permanent shutdown during overvoltage faults. IC Role / Device Role / Timing Role: Voltage-triggered shunt element that conducts only during overvoltage, allowing breaker/fuse coordination. Use Value: Enables system reset after transient clearance - unlike sacrificial crowbars - supporting high-availability infrastructure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150AHE3/52 | Lower PPPM (600 W), smaller SMB package, same VWM/VBR range, identical AEC-Q101 qualification | Not suitable for IEC 61000-4-5 Level 4; limited to board-level ESD and lower-energy transients | Select when space-constrained layouts or lower surge threat levels apply; requires PCB layout review for thermal relief |
| 1.5KE150A | Same VWM/VBR/VC specs, but 1.5 kW PPPM, DO-201 package, no AEC-Q101 qualification, JESD 201 class 1A whisker test | Lacks automotive qualification; not recommended for under-hood or safety-critical systems | Acceptable for commercial/industrial power supplies where AEC-Q101 is not mandated and surge energy ≤1.5 kW |
Compared with SMBJ150AHE3/52 and 1.5KE150A, the 5KP150AHE3_A/C delivers 3.3× higher surge energy handling and certified automotive reliability - making it the sole choice for high-power, mission-critical transient suppression where 5000 W clamping and AEC-Q101 validation are mandatory.

FAQ
What is the clamping voltage of the 5KP150AHE3_A/C under a 10/1000 μs surge?
The 5KP150AHE3_A/C clamps to a maximum of 243 V at its rated peak pulse current of 20.6 A under a 10/1000 μs waveform. This value is measured per JEDEC standard test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The 5KP150AHE3_A/C achieves this with a clamping ratio (VC/VBR) of approximately 1.46, indicating tight voltage control relative to its breakdown range.
Is the 5KP150AHE3_A/C suitable for automotive applications?
Yes, the 5KP150AHE3_A/C is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes JESD 201 class 2 whisker-resistant matte tin plating, UL 94 V-0 compliant molding compound, and operation up to +175 °C junction temperature - all validated per AEC-Q101 stress test requirements. The 5KP150AHE3_A/C is commonly deployed in engine control units, body control modules, and ADAS power inputs.
What does the "HE3_A/C" suffix mean in 5KP150AHE3_A/C?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified construction with JESD 201 class 2 whisker resistance; "A/C" indicates the revision code and packaging format - specifically, 13" diameter paper tape and reel with 800 units per reel. The "A" is the revision level per Vishay's internal change control, and "C" is the preferred package code per ordering documentation. This matches the official Vishay ordering example shown in Document 88308.
How does the 5KP150AHE3_A/C differ from the 5KP150A-E3/54 variant?
The 5KP150AHE3_A/C and 5KP150A-E3/54 share identical electrical specifications and P600 package, but differ in qualification and packaging: the HE3 version is AEC-Q101 qualified and uses class 2 whisker-resistant plating, whereas the E3/54 is commercial-grade (no AEC-Q101) and shipped in 54-reel packaging. Both have the same 150 V VWM and 243 V VC, but only the 5KP150AHE3_A/C is approved for automotive under-hood deployment.
Can the 5KP150AHE3_A/C be used in bidirectional configurations?
No, the 5KP150AHE3_A/C is unidirectional only, with cathode marked by a color band. It clamps only in reverse bias and conducts forward current like a standard diode. For bidirectional protection, two 5KP150AHE3_A/C devices must be connected in series opposition, or a dedicated bidirectional TVS such as the 5KP150CA should be selected - which is a distinct part number with symmetrical breakdown characteristics.
