Product details
Overview
5KP90HE3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection of DC power rails and signal lines. It features 5000 W peak pulse power (10/1000 µs), 90 V stand-off voltage (VWM), 100–111 V breakdown voltage (VBR), clamping voltage of 146 V at 34.2 A peak current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the 5KP90HE3/73 datasheet, 5KP90HE3/73 pinout, 5KP90HE3/73 application, or 5KP90HE3/73 equivalent, this device is selected for robust overvoltage protection in switching power supplies, automotive ECUs, industrial motor drives, and telecom line interfaces where fast response (<1 ns), low clamping ratio, and high surge current tolerance are critical.
Technical Context
The 5KP90HE3/73 employs a glass-passivated P600 junction optimized for uni-directional clamping, with a 10/1000 µs waveform rating per JEDEC standards. Its 175 °C maximum junction temperature and 8.0 W steady-state power dissipation enable operation in thermally constrained environments without active cooling.
It delivers 34.2 A peak pulse current (IPPM) at 146 V clamping voltage (VC) with <0.1% duty cycle, and exhibits 2.0 µA max reverse leakage at 90 V. The device's 0.110 %/°C VBR temperature coefficient ensures stable breakdown behavior across automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 90 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 12 V/24 V/48 V systems. |
| VBR @ IT = 5.0 mA | 100–111 V - Breakdown voltage range confirming reliable turn-on during transients above nominal supply. |
| VC @ IPPM = 34.2 A | 146 V - Clamped voltage under 5000 W surge; limits downstream IC stress to safe levels during lightning or ESD events. |
| PPPM | 5000 W - Peak pulse power handling capability with 10/1000 µs waveform; suitable for IEC 61000-4-5 Level 4 surges. |
| IFSM | 600 A - Non-repetitive forward surge current rating (8.3 ms half-sine); supports crowbar-style fault clearing in power supplies. |
| TJ Range | −55 °C to +175 °C - Full automotive-grade operating and storage temperature range; validated per AEC-Q101. |
| Package | P600 - Axial-leaded, molded epoxy case (9.5 mm length, 5.4 mm diameter) with UL 94 V-0 flammability rating. |
Pinout & Package
P600 package: axial-leaded, cylindrical epoxy body with cathode band marking; leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102; RoHS-compliant and AEC-Q101 qualified (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in uni-directional clamp configuration. |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 24 V rail); color band identifies this end for correct PCB orientation. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 µs) | Enables single-device protection against severe surges (e.g., ISO 7637-2 Pulse 5a) without parallel stacking. |
| AEC-Q101 qualification | Validated for automotive under-hood and ECU applications requiring zero defect rates and extended temperature cycling. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for sensitive MOSFET gates and MCU I/O. |
| Glass-passivated P600 junction | Ensures long-term stability and low leakage (<2 µA) after repeated surge events, critical for battery-backed systems. |
| UL 94 V-0 molding compound | Provides flame-retardant housing essential for industrial and transportation equipment compliance. |
Applications
| Automotive Power Distribution | Industrial Motor Drive DC Bus |
|---|---|
Use Scenario: Protection of 24 V battery-fed control modules against load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Uni-directional TVS placed between battery rail and ground to clamp transients up to 120 V. Use Value: Withstands 5000 W surges while limiting clamped voltage to 146 V, preventing damage to CAN transceivers and microcontrollers. |

IC Role / Device Role / Timing Role: DC bus clamp on 300–400 V intermediate circuit to absorb regenerative energy spikes. Use Value: Fast sub-nanosecond response and 600 A IFSM rating allow it to replace crowbar circuits and enable fuse coordination. |
| Telecom Line Interface | Switching Power Supply Output |
Use Scenario: Secondary-side surge protection on PoE-powered Ethernet ports (IEEE 802.3af/at) against induced lightning surges. IC Role / Device Role / Timing Role: Uni-directional clamp on 48 V DC output line, referenced to common-mode ground. Use Value: 146 V clamping voltage ensures protected PHY ICs remain within absolute maximum ratings during 10/1000 µs surges. |
Use Scenario: Overvoltage suppression on the regulated output of 12 V/24 V AC-DC adapters used in medical and test equipment. IC Role / Device Role / Timing Role: Final-stage TVS placed immediately after output filter capacitor to suppress switching noise and fault transients. Use Value: 90 V VWM provides 20% headroom above nominal 75 V max output, enabling fail-safe shutdown without nuisance tripping. |
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 SMAJ90A | Lower peak power (400 W), SMA package (surface-mount), 90 V VWM, 146 V VC at 16.7 A. | Suitable for space-constrained PCBs but lacks AEC-Q101 qualification and cannot handle 5000 W surges. | Select when board area is limited and surge energy is ≤400 W; not recommended for automotive or industrial mains-connected systems. |
| ON Semiconductor 1.5KE91A | Same P600 package, 91 V VWM, 5000 W rating, but only commercial-grade (not AEC-Q101 qualified); higher VC (150 V). | Acceptable for industrial controls but excluded from automotive OEM BOMs requiring AEC-Q101 evidence. | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated; verify thermal derating at TL > 75 °C. |
Compared with SMAJ90A and 1.5KE91A, the 5KP90HE3/73 uniquely combines AEC-Q101 qualification, 5000 W capability, and P600 axial form factor-making it the only option for high-energy, automotive-grade, through-hole surge protection without redesigning layout or compromising reliability.

FAQ
What is the clamping voltage of the 5KP90HE3/73 under maximum surge conditions?
The 5KP90HE3/73 clamps to 146 V at its rated peak pulse current of 34.2 A (10/1000 µs waveform). This value is measured per JEDEC standards and represents the maximum voltage seen by downstream components during a full 5000 W transient event. The 5KP90HE3/73 maintains this clamping performance across its full operating temperature range, with minimal drift due to its 0.110 %/°C VBR coefficient.
Is the 5KP90HE3/73 suitable for automotive applications?
Yes, the 5KP90HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its −55 °C to +175 °C junction temperature range, robust P600 package, and validation against mechanical shock, temperature cycling, and humidity testing meet OEM requirements. The HE3 suffix denotes AEC-Q101 compliance, distinguishing it from commercial-grade variants like 5KP90A-E3/73.
How does the 5KP90HE3/73 differ from the 5KP90A-E3/73?
The 5KP90HE3/73 is AEC-Q101 qualified and meets JESD 201 Class 2 whisker resistance, while the 5KP90A-E3/73 is commercial-grade (JESD 201 Class 1A). Both share identical electrical specs (VWM = 90 V, VC = 146 V), but only the HE3 version carries automotive qualification documentation and undergoes additional stress testing. The 5KP90HE3/73 is required for Tier 1 automotive BOMs.
Can the 5KP90HE3/73 be used in bidirectional configurations?
No, the 5KP90HE3/73 is strictly unidirectional, as confirmed in the Vishay datasheet. It conducts only in forward bias and clamps in reverse bias. For bidirectional protection, two 5KP90HE3/73 devices must be connected in series opposition, or a dedicated bidirectional part such as 5KP90CA should be selected-though that variant is not AEC-Q101 qualified.
What is the maximum allowable lead temperature during soldering for the 5KP90HE3/73?
The 5KP90HE3/73 supports solder dip at 275 °C maximum for 10 seconds per JESD 22-B106. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for solderability. Reflow profiles must stay within this limit to avoid delamination or junction degradation; exceeding 275 °C risks compromising the glass-passivated chip junction integrity of the 5KP90HE3/73.
