Product details
Overview
5KP17A-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping on power rails and signal lines. It features 5000 W peak pulse power (10/1000 μs), 17.0 V stand-off voltage (VWM), 27.6 V maximum clamping voltage at 181 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the 5KP17A-E3/54 datasheet, 5KP17A-E3/54 pinout, 5KP17A-E3/54 application, or 5KP17A-E3/54 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDS/VCC, IPPM derating above 25 °C, unidirectional polarity alignment with DC rail topology, and P600 thermal pad layout compatibility for 8.0 W continuous dissipation.
Technical Context
This TVS operates as a voltage-clamped crowbar element during transients - avalanche breakdown initiates at VBR = 18.9–20.9 V (5 mA test current), clamping to ≤27.6 V at 181 A. Its P600 glass-passivated junction enables low incremental surge resistance and sub-nanosecond response time, critical for protecting MOSFETs and ICs against lightning-induced surges and inductive switching spikes.
Thermal design relies on lead temperature (TL) derating: power dissipation drops from 8.0 W at TL = 75 °C to zero at TL = 175 °C. The device sustains 500 A non-repetitive forward surge (8.3 ms half-sine) and exhibits +0.097 %/°C VBR temperature coefficient - enabling predictable clamping across -55 to +175 °C junction range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17.0 V - Maximum continuous reverse voltage before leakage exceeds 2.0 μA; sets upper limit for DC rail operation without conduction. |
| VBR @ 5 mA | 18.9–20.9 V - Breakdown onset range; ensures reliable turn-on before downstream component overvoltage thresholds. |
| VC @ IPPM | 27.6 V - Clamped voltage at 181 A peak pulse; defines worst-case stress on protected load during 10/1000 μs surge. |
| PPPM | 5000 W - Peak pulse power handling per JEDEC 10/1000 μs waveform; supports single-event lightning strike suppression. |
| TJ max. | +175 °C - Maximum junction temperature; enables placement near hot-switching nodes with adequate heatsinking. |
| Polarity | Unidirectional - Cathode marked by band; suitable only for DC-biased rails where reverse conduction must be blocked. |
Pinout & Package
Package: P600 molded epoxy case with glass-passivated chip junction; UL 94 V-0 rated; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker testing (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; carries full surge current during clamping event. |
| Cathode | High-side connection point | Marked by color band; ties to protected line (e.g., 12 V rail); avalanche conduction occurs cathode-to-anode. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood applications including engine control units and body electronics. |
| 5000 W peak pulse power | Withstands IEC 61000-4-5 Level 4 (4 kV line-earth) surges without degradation when properly mounted. |
| Low clamping ratio (VC/VWM = 1.62) | Minimizes overvoltage margin required between protected IC's absolute maximum rating and VWM. |
| Fast response time (<1 ns) | Activates before transient energy couples into sensitive circuitry, preventing latch-up or gate oxide damage. |
| P600 thermal mass | Enables 8.0 W continuous power dissipation at TL = 75 °C - supports sustained fault conditions in industrial power supplies. |
Applications
| Automotive Power Rail Protection | Industrial DC Power Supply Output |
|---|---|

Use Scenario: Protecting 12 V battery-fed ECUs from load dump transients (ISO 7637-2 Pulse 5a, up to 120 V/100 ms). IC Role / Device Role / Timing Role: Unidirectional TVS clamps overvoltage to ≤27.6 V within nanoseconds, preserving MCU, CAN transceivers, and sensor interfaces. Use Value: Prevents permanent damage during alternator field collapse events while maintaining system reset capability after fuse clearing. |
Use Scenario: Safeguarding 24 V output of industrial SMPS against inductive kickback from solenoid drivers and motor controllers. IC Role / Device Role / Timing Role: Acts as primary overvoltage clamp in parallel with output capacitor, absorbing 5000 W surges without requiring crowbar SCR/fuse coordination. Use Value: Eliminates need for complex active shutdown circuits, reducing BOM count and enabling rapid recovery after transient clearance. |
| Telecom Line Interface Protection | Consumer Appliance Motor Drive Stage |
|

IC Role / Device Role / Timing Role: Mounted at connector entry point; clamps common-mode transients to protect PHY layer ICs and isolation barriers. Use Value: Maintains data integrity during Category C (10/700 μs) telecom surges while meeting IEC 61000-4-5 immunity requirements. |
Use Scenario: Suppressing back-EMF spikes generated by brushed DC motors in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Placed across motor terminals to shunt inductive energy away from H-bridge MOSFETs and gate drivers. Use Value: Extends MOSFET lifetime by limiting VDS overshoot to 27.6 V, avoiding avalanche fatigue and thermal runaway. |
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 PPPM (600 W), SMC package, same VWM (17 V), higher VC (27.7 V) | Not suitable for IEC 61000-4-5 Level 4; limited to board-level ESD and lower-energy transients. | Select SMBJ17A only for space-constrained consumer designs where 5000 W surge capacity is unnecessary. |
| 5KP17CA-E3/54 | Same PPPM, VWM, and package, but bidirectional (±17 V symmetric clamping) | Required for AC-coupled or floating signal lines (e.g., audio, differential sensors); unsuitable for polarized DC rails. | Choose 5KP17CA-E3/54 when protecting balanced interfaces or systems with undefined voltage polarity during fault conditions. |
Compared with SMBJ17A and 5KP17CA-E3/54, the 5KP17A-E3/54 uniquely delivers automotive-grade 5000 W unidirectional clamping in P600 - making it optimal for high-reliability DC power rail protection where polarity is fixed and surge energy exceeds 1 kV·A.

FAQ
What is the clamping voltage of the 5KP17A-E3/54 under maximum rated surge current?
The 5KP17A-E3/54 clamps to a maximum of 27.6 V when subjected to its rated peak pulse current of 181 A (10/1000 μs waveform). This value is measured at the device terminals under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during a full-power transient event. Designers must ensure downstream components' absolute maximum ratings exceed this clamping voltage with margin.
Is the 5KP17A-E3/54 suitable for automotive applications?
Yes, the 5KP17A-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its operating junction temperature range of -55 °C to +175 °C, robust P600 package, and validated surge performance make it appropriate for engine control units, body control modules, and ADAS power domains where ISO 7637-2 and IEC 61000-4-5 compliance is required.
How does the unidirectional polarity of the 5KP17A-E3/54 affect circuit placement?
The 5KP17A-E3/54 is unidirectional and must be oriented with its cathode (marked by color band) toward the positive side of a DC rail. It conducts only during positive overvoltage events and blocks reverse voltage - making it incompatible with AC or bidirectional signal lines. Incorrect orientation results in no clamping action during positive transients and possible failure due to reverse breakdown.
What thermal considerations apply to the 5KP17A-E3/54 in continuous operation?
The 5KP17A-E3/54 dissipates up to 8.0 W when lead temperature (TL) is maintained at 75 °C, with linear derating to zero at 175 °C. PCB layout must provide sufficient copper area on both anode and cathode pads for heat conduction, and mounting surface thermal resistance must be calculated to ensure TL stays within spec during sustained fault conditions or repetitive surges.
Can the 5KP17A-E3/54 replace older 5KP17A variants with different suffixes?
The 5KP17A-E3/54 is RoHS-compliant and meets JESD 201 Class 1A whisker testing; it replaces legacy 5KP17A parts with E3 suffix in commercial-grade applications. However, it is not a direct substitute for HE3-suffix variants (AEC-Q101 qualified with Class 2 whisker rating) unless automotive qualification is not required. Always verify packaging (P600), electrical specs, and compliance documentation before cross-referencing.
