Product details
Overview
5KP54-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection with 5000 W peak pulse power (10/1000 μs), 54 V stand-off voltage (VWM), and 87.1 V maximum clamping voltage (VC) at 57.4 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the 5KP54-E3/73 datasheet, 5KP54-E3/73 pinout, 5KP54-E3/73 application, or 5KP54-E3/73 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, low incremental surge resistance, and compatibility with 13" tape-and-reel delivery for automated assembly.
Technical Context
The 5KP54-E3/73 employs a glass-passivated P600 chip junction optimized for fast response to transients induced by inductive load switching or lightning surges. Its unidirectional architecture provides reverse-biased clamping only, with breakdown voltage (VBR) specified at 60.0–66.3 V and test current of 50 mA.
It operates within -55 °C to +175 °C junction temperature range and supports repetitive surge duty cycles up to 0.01 %, with thermal derating above 25 °C per Fig. 2. The device meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 1A whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Applications
| Automotive Power Rail Protection | Industrial DC Power Supply Output |
|---|---|
Use Scenario: Protecting 48 V/54 V battery-fed ECUs against load dump transients per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges above 54 V. Use Value: Withstands 5000 W pulses and 600 A surge current while limiting clamped voltage to 87.1 V-within safe margin for 100 V-rated MOSFETs and controllers. | Use Scenario: Safeguarding output stage of 54 V telecom or factory automation DC-DC converter. IC Role / Device Role / Timing Role: Primary overvoltage suppression element parallel to output capacitor, triggered by inductive kickback or feedback loop failure. Use Value: Fast <1 ns response ensures clamping before downstream LDOs or microcontrollers experience latch-up or gate oxide rupture. |
| Sensor Signal Line Protection | MOSFET Gate Driver Protection |
Use Scenario: Shielding CAN or LIN bus transceivers and analog sensor inputs in harsh industrial environments. IC Role / Device Role / Timing Role: Low-leakage (≤2 μA at 54 V) unidirectional TVS placed at connector entry point to shunt ESD and cable discharge events. Use Value: 54 V VWM allows full system operation without false triggering; 87.1 V VC prevents damage to 70 V-rated transceiver inputs. | Use Scenario: Preventing gate oxide failure in high-side N-channel MOSFET drivers subjected to Miller-induced voltage spikes. IC Role / Device Role / Timing Role: Clamp diode connected between gate and source, suppressing dv/dt-induced overshoot exceeding 54 V threshold. Use Value: Low incremental surge resistance ensures minimal voltage overshoot during fast turn-off transients, preserving gate reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ54A-E3/52 | Lower peak power (600 W), smaller SMB package, same VWM (54 V), higher VC (93.6 V) | Not suitable for load dump; limited to board-level ESD and low-energy transients | Select when space-constrained and surge energy is ≤600 W |
| 1.5KE56A | Same P600 package, 56 V VWM, 5000 W rating, but non-AEC-Q101 and higher VC (93.6 V) | Lacks automotive qualification; used in commercial/industrial power supplies only | Select when AEC-Q101 is not required and 56 V standoff suffices |
Compared with SMBJ54A-E3/52 and 1.5KE56A, the 5KP54-E3/73 delivers superior surge robustness (5000 W), automotive-grade reliability (AEC-Q101), and tighter clamping (87.1 V), making it optimal for high-risk 54 V systems where failure modes demand highest immunity.

FAQ
What is the clamping voltage of the 5KP54-E3/73 under maximum rated surge current?
The 5KP54-E3/73 clamps to a maximum of 87.1 V when subjected to its rated peak pulse current of 57.4 A (10/1000 μs waveform). This value is measured per JEDEC standards and guarantees protection margin for 100 V-rated downstream components. The 5KP54-E3/73 achieves this with low incremental surge resistance, ensuring predictable voltage limiting during transient events.
Is the 5KP54-E3/73 suitable for automotive applications?
Yes, the 5KP54-E3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, robust P600 package, and compliance with load dump standards (ISO 7637-2) make it appropriate for engine control units, ADAS power rails, and body electronics. The 5KP54-E3/73 meets JESD 201 Class 1A whisker testing and RoHS requirements.
What does the "E3/73" suffix indicate in 5KP54-E3/73?
The "E3" denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "73" specifies the preferred packaging code for 13-inch paper tape and reel, with 800 units per reel. This differs from /54 (also 800/reel) and confirms the 5KP54-E3/73 is supplied in standard surface-mount compatible format for automated placement. The 5KP54-E3/73 ordering code ensures traceable, production-ready logistics.
How does the 5KP54-E3/73 compare to bidirectional TVS diodes?
The 5KP54-E3/73 is unidirectional only, meaning it clamps reverse-voltage transients on a 54 V line but conducts forward current like a rectifier above ~3.5 V. Bidirectional variants (e.g., 5KP54CA) protect AC or dual-polarity signals but sacrifice ~10 % clamping efficiency. The 5KP54-E3/73 is preferred for DC power rails where polarity is fixed and forward conduction must be avoided-its design ensures no unintended forward path in normal operation.
What thermal considerations apply when using the 5KP54-E3/73 in high-power surge scenarios?
The 5KP54-E3/73 has a 8.0 W steady-state power dissipation rating on an infinite heatsink at 75 °C lead temperature (TL), with linear derating above 25 °C ambient. For repeated surges, thermal mass and PCB copper area are critical: minimum 1 in² (6.5 cm²) of 2 oz copper per side recommended. The 5KP54-E3/73's 175 °C TJ max allows short-term surge heating, but sustained operation requires adherence to Fig. 5 derating curves to avoid parametric shift or failure.
