Product details
Overview
5KP17AHE3_A/C from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection with 5000 W peak pulse power (10/1000 μs), 17.0 V stand-off voltage (VWM), and 27.6 V clamping voltage (VC) at 181 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the 5KP17AHE3_A/C datasheet, 5KP17AHE3_A/C pinout, 5KP17AHE3_A/C application, or 5KP17AHE3_A/C equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, low incremental surge resistance, and P600 mechanical robustness for high-reliability board-level surge suppression.
Technical Context
This TVS diode uses a glass passivated P600 chip junction to achieve fast response time (<1 ns) and excellent clamping performance under repetitive 10/1000 μs transients at 0.01 % duty cycle. Its unidirectional structure provides low forward voltage (3.5 V at 100 A) and enables crowbar-circuit replacement in DC power rail protection.
Thermal design relies on lead temperature derating: power dissipation drops from 8.0 W at TL = 75 °C to zero at TL = 175 °C. The device meets JESD 22-B106 solder dip (275 °C, 10 s) and JESD 201 class 2 whisker test (HE3 suffix), confirming suitability for automotive reflow and long-term reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17.0 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system working voltage margin. |
| VBR min/max | 18.9 V / 20.9 V at 5.0 mA - Breakdown threshold range defining turn-on consistency across production lots. |
| VC @ IPPM | 27.6 V at 181 A - Clamped voltage during 10/1000 μs surge; determines protected circuit's maximum transient stress. |
| PPPM | 5000 W - Peak pulse power handling capability; defines survivability against lightning or inductive switch-off surges. |
| IFSM | 500 A - 8.3 ms half-sine surge current rating; supports fuse/breaker coordination without device failure. |
| TJ max | 175 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17A | Lower peak power (600 W), SMC package, same VWM (17 V), higher VC (27.7 V) | Not rated for AEC-Q101; limited to commercial-grade consumer/industrial use | Select when space-constrained layouts require smaller footprint and surge energy is ≤600 W. |
| 1.5KE18A | Same P600 package, lower peak power (1500 W), identical VWM/VBR, higher VC (30.0 V) | Lacks AEC-Q101 qualification and JESD 201 class 2 whisker rating | Choose for cost-sensitive non-automotive applications where 1500 W surge capacity suffices. |
Compared with SMBJ17A and 1.5KE18A, the 5KP17AHE3_A/C delivers 3.3× and 3.3× higher peak pulse power respectively, maintains tighter VC tolerance, and is the only option qualified for automotive under-hood deployment with validated long-term whisker resistance.

FAQ
What is the clamping voltage of the 5KP17AHE3_A/C under maximum surge conditions?
The 5KP17AHE3_A/C clamps to 27.6 V at its rated peak pulse current of 181 A (10/1000 μs waveform). This value is measured per JEDEC standards and represents the maximum voltage seen by downstream circuitry during a full-rated transient event. The clamping performance remains stable across temperature and lifetime when mounted per Vishay's thermal guidelines.
Is the 5KP17AHE3_A/C suitable for automotive applications?
Yes, the 5KP17AHE3_A/C is AEC-Q101 qualified and meets JESD 201 class 2 whisker resistance requirements, making it suitable for under-hood automotive modules including engine control units, body controllers, and ADAS power supplies. Its 175 °C max junction temperature and robust P600 package support harsh thermal environments.
What does the "HE3_A/C" suffix indicate in 5KP17AHE3_A/C?
The "HE3" denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 class 2 whisker resistance. "_A/C" specifies the revision code (A) and preferred packaging code (C), indicating 800-unit reels on 13″ diameter paper tape per Vishay's ordering matrix. The full part number 5KP17AHE3_A/C uniquely identifies this qualified variant.
How does the 5KP17AHE3_A/C compare to standard 1.5 kW TVS diodes like 1.5KE17A?
The 5KP17AHE3_A/C delivers 5000 W peak pulse power-more than three times that of 1.5KE17A (1500 W)-while maintaining comparable VWM (17.0 V) and lower clamping voltage (27.6 V vs. 30.0 V). It also adds AEC-Q101 qualification and class 2 whisker resistance, which 1.5KE17A lacks. These attributes make 5KP17AHE3_A/C appropriate for higher-energy, mission-critical protection.
Can the 5KP17AHE3_A/C be used in AC line applications?
No, the 5KP17AHE3_A/C is unidirectional and rated only for DC applications. Its cathode-marked polarity and lack of bidirectional symmetry prevent safe use on AC mains or transformer secondaries. For AC line protection, bidirectional TVS devices such as 5KP17CA must be selected instead.
