Product details
Overview
5KP90AHE3_A/C from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 90 V stand-off voltage (VWM), 100–111 V breakdown range (VBR), 146 V maximum clamping voltage at 34.2 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs). It is AEC-Q101 qualified and used to protect MOSFETs and ICs against lightning-induced surges in automotive power supplies.
For engineers reviewing the 5KP90AHE3_A/C datasheet, 5KP90AHE3_A/C pinout, 5KP90AHE3_A/C application, or 5KP90AHE3_A/C equivalent, key selection criteria include clamping voltage margin relative to protected device's absolute maximum rating, unidirectional polarity compatibility with DC bias schemes, thermal derating above 25 °C, and P600 mechanical mounting requirements for high-energy transient dissipation.
Technical Context
The 5KP90AHE3_A/C operates as a silicon avalanche diode that enters controlled reverse conduction when transient voltage exceeds its breakdown threshold (VBR = 100–111 V at 5 mA). Its low incremental surge resistance ensures stable clamping under high-current transients up to 34.2 A (10/1000 μs).
It is rated for non-repetitive operation at 0.01 % duty cycle and requires heatsinking for sustained power dissipation-8.0 W on infinite heatsink at TL = 75 °C. Junction temperature must remain within –55 °C to +175 °C, with thermal derating beginning above TA = 25 °C per published curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 90 V - Maximum continuous reverse voltage before significant leakage; sets upper limit for normal operating DC rail voltage. |
| VBR (Breakdown Voltage) | 100–111 V at 5 mA - Confirmed avalanche onset range; defines minimum transient threshold for clamping activation. |
| VC (Clamping Voltage) | 146 V at IPPM = 34.2 A - Peak voltage seen by protected circuit during worst-case 10/1000 μs surge; determines required voltage headroom. |
| PPPM (Peak Pulse Power) | 5000 W (10/1000 μs) - Energy-handling capacity for single transient events; validates suitability for lightning-level surges. |
| IFSM (Surge Current) | 500 A (8.3 ms half-sine) - Withstands short-duration overcurrent without failure; supports crowbar-circuit replacement use cases. |
| TJ max. | +175 °C - Maximum junction temperature; enables operation in under-hood automotive environments with proper PCB copper area. |
| Polarity | Unidirectional - Cathode marked by band; intended for DC-biased applications where reverse conduction is acceptable during fault. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; meets UL 94 V-0 flammability rating and JESD 22-B102 solderability. Cathode indicated by color band. Lead finish complies with JESD 201 Class 2 whisker test (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected circuit (e.g., ground or return path); conducts during forward surge events. |
| Cathode | Reverse-biased clamping terminal | Connected to higher-potential side (e.g., +12 V rail); initiates avalanche conduction when transient exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing-enables use in engine control units and body electronics. |
| 5000 W peak pulse power (10/1000 μs) | Handles IEC 61000-4-5 Level 4 surges (4 kV line-to-earth) without degradation when properly mounted on ≥1 in² copper pour. |
| Low clamping ratio (VC/VBR ≈ 1.32) | Minimizes overvoltage stress on downstream components-critical for protecting 100 V-rated MOSFETs and gate drivers. |
| P600 glass-passivated junction | Ensures stable VBR tolerance and long-term parameter stability under thermal cycling and humidity exposure. |
| Unidirectional configuration | Optimized for DC power rail protection where reverse conduction during fault is acceptable and forward surge immunity is required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90A | Lower PPPM (600 W), smaller SMB package, same VWM/VBR range, bidirectional option available | Not suitable for IEC 61000-4-5 Level 4; limited to board-level ESD and low-energy switching noise | Select 5KP90AHE3_A/C when >1 kW surge energy or automotive AEC-Q101 compliance is required. |
| 1.5KE91A | Same P600 package and 5000 W rating, but older 1.5KE series; VBR = 101–112 V, VC = 146 V, no AEC-Q101 qualification | Lacks automotive qualification and updated thermal performance data; not recommended for new automotive designs | Choose 5KP90AHE3_A/C for production programs requiring documented AEC-Q101 evidence and extended temperature validation. |
Compared with SMBJ90A and 1.5KE91A, the 5KP90AHE3_A/C provides verified AEC-Q101 qualification, tighter VBR tolerance (100–111 V vs. 101–112 V), and guaranteed 5000 W pulse power with defined 10/1000 μs waveform compliance-making it the preferred choice for mission-critical automotive and industrial surge protection.

FAQ
What is the clamping voltage of the 5KP90AHE3_A/C at its rated peak pulse current?
The 5KP90AHE3_A/C has a maximum clamping voltage (VC) of 146 V when subjected to its rated peak pulse current (IPPM) of 34.2 A using the standard 10/1000 μs waveform. This value is measured under JEDEC conditions and represents the highest voltage the protected circuit will experience during a worst-case transient event. The 5KP90AHE3_A/C maintains this clamping performance across its specified operating temperature range.
Is the 5KP90AHE3_A/C suitable for automotive applications?
Yes, the 5KP90AHE3_A/C is AEC-Q101 qualified and explicitly rated for automotive use. Its construction-including P600 package with glass-passivated junction, matte tin-plated leads meeting JESD 201 Class 2 whisker resistance, and operation from –55 °C to +175 °C-supports deployment in engine control units, body control modules, and ADAS power supplies. The 5KP90AHE3_A/C appears in Vishay's official AEC-Q101 qualified product list with full test report documentation.
How does the 5KP90AHE3_A/C differ from the 5KP90A-E3 variant?
The 5KP90AHE3_A/C differs from the 5KP90A-E3 primarily in qualification and packaging: the "H" denotes AEC-Q101 qualification, while "E3" alone indicates commercial-grade RoHS compliance only. The "_A/C" suffix specifies tape-and-reel packaging in 13-inch diameter reels with 800-unit base quantity and C-coded packaging. The 5KP90AHE3_A/C also meets JESD 201 Class 2 whisker testing, whereas standard E3 meets Class 1A.
What is the maximum operating temperature for the 5KP90AHE3_A/C junction?
The maximum junction temperature (TJ max.) for the 5KP90AHE3_A/C is +175 °C. This rating allows reliable operation in high-ambient environments such as under-hood automotive locations or enclosed industrial enclosures. Thermal design must account for power dissipation derating above 25 °C ambient, as shown in Figure 2 of the datasheet, and ensure adequate PCB copper area or heatsinking to maintain TJ ≤ 175 °C during transient events. The 5KP90AHE3_A/C retains full specification compliance up to this limit.
Can the 5KP90AHE3_A/C be used in bidirectional protection circuits?
No, the 5KP90AHE3_A/C is unidirectional only, as confirmed in the "Polarity" section of the datasheet and indicated by the cathode band marking. It conducts in reverse during overvoltage events but blocks forward current above ~3.5 V. For bidirectional AC or symmetrical DC protection, a separate pair of unidirectional devices or a dedicated bidirectional TVS (e.g., 5KP90CA) must be used. Using the 5KP90AHE3_A/C in bidirectional configurations risks forward conduction failure or inadequate clamping.
