Product details
Overview
5KP30HE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, rated for 30 V stand-off voltage (VWM), 33.3–36.8 V breakdown (VBR), and 5000 W peak pulse power (10/1000 µs). It clamps transients to ≤48.4 V at 103 A, with AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the 5KP30HE3/54 datasheet, 5KP30HE3/54 pinout, 5KP30HE3/54 application, or 5KP30HE3/54 equivalent, this device is selected for high-energy surge suppression in DC power rails, MOSFET gate protection, and sensor interface lines where fast response (<1 ns), low clamping ratio, and robust 175 °C junction operation are required.
Technical Context
The 5KP30HE3/54 uses a glass-passivated P600 chip junction optimized for uni-directional clamping of positive-going transients on grounded-rail configurations. Its 10/1000 µs waveform rating supports repetitive surge events at 0.01 % duty cycle, with thermal derating above 25 °C per Fig. 2.
Clamping performance is defined by VC = 48.4 V at IPPM = 103 A, yielding a clamping ratio (VC/VWM) of 1.61 - critical for ensuring downstream ICs remain below absolute maximum ratings during lightning or inductive-switching events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30 V - Maximum continuous reverse operating voltage before conduction begins; sets safe DC rail margin. |
| VBR (min/max) | 33.3 V / 36.8 V at 5.0 mA - Confirmed breakdown range ensures reliable turn-on without premature leakage. |
| VC @ IPPM | 48.4 V at 103 A - Clamped voltage under full 5 kW surge; determines protected circuit's worst-case overvoltage exposure. |
| PPPM | 5000 W (10/1000 µs) - Peak transient energy handling capacity; enables replacement of crowbar circuits in PSU outputs. |
| TJ max. | 175 °C - Enables operation in under-hood automotive environments and high-ambient industrial enclosures. |
| Polarity | Uni-directional - Requires cathode-to-rail orientation; not suitable for bidirectional AC line protection without external circuitry. |
| Qualification | AEC-Q101 qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD. |
Pinout & Package
Package: P600 molded epoxy body (9.5 mm × 8.6 mm × 3.4 mm), RoHS-compliant matte tin-plated leads, UL 94 V-0 rated compound. Cathode denoted by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current sink path | Connected to protected line; conducts surge current to ground when V > VBR. |
| Cathode | Reference node / Ground return | Must be tied to system ground plane; defines clamping reference point and polarity direction. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power | Supports single-event lightning surges (IEC 61000-4-5 Level 4) on 24 V/48 V DC systems without failure. |
| Fast response time (<1 ns) | Clamps transients before sensitive logic or analog circuitry experiences overvoltage stress. |
| Low incremental surge resistance | Minimizes voltage overshoot during rapid di/dt events, improving clamping predictability. |
| AEC-Q101 qualification | Validates long-term reliability in automotive powertrain and ADAS modules subject to thermal shock and vibration. |
| 175 °C max junction temperature | Permits placement near heat-generating components (e.g., MOSFETs, inductors) without thermal derating penalties. |
Applications
| Automotive Power Rail Protection | Industrial DC Motor Drive Outputs |
|---|---|
Use Scenario: Suppressing load-dump transients (up to 120 V, 400 ms) on 12 V/24 V vehicle battery rails. IC Role / Device Role / Timing Role: Uni-directional TVS placed between battery feed and ECUs, clamping excess voltage within nanoseconds. Use Value: Prevents latch-up or permanent damage to microcontrollers and CAN transceivers during alternator regulation faults. | Use Scenario: Protecting IGBT gate drivers and feedback sensors from flyback spikes generated by brushed/BLDC motor commutation. IC Role / Device Role / Timing Role: Clamp diode across motor terminals or driver supply rail, absorbing inductive kickback energy. Use Value: Eliminates need for snubber RC networks while maintaining <100 ns response and 5 kW surge capability. |
| Telecom DC Power Feeds | Renewable Energy Inverter DC Links |
Use Scenario: Guarding PoE-powered equipment inputs against induced surges from nearby lightning strikes on outdoor cabling. IC Role / Device Role / Timing Role: Primary surge clamp on 48 V DC input stage, coordinated with upstream GDT or MOV. Use Value: Limits let-through voltage to <50 V, preserving IEEE 802.3af/at compliance and preventing PHY IC damage. | Use Scenario: Safeguarding high-voltage DC bus (300–800 V) pre-charge circuits and capacitor banks in solar inverters. IC Role / Device Role / Timing Role: Secondary-level TVS on auxiliary control rails (e.g., 24 V bias supply), not main DC link. Use Value: Provides localized protection for gate drivers and isolation amplifiers without compromising main-link efficiency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30AHE3/52 | Lower PPPM (600 W), same VWM (30 V), DO-214AA package, smaller footprint | Not rated for AEC-Q101; limited to commercial/industrial use | Select when space-constrained PCB layout prioritizes size over 5 kW surge handling. |
| 5KP33HE3/54 | Higher VWM (33 V), VBR 36.7–40.6 V, VC = 53.3 V at 93.8 A - 10 % higher clamping voltage | Same P600 package and AEC-Q101 qualification; used where 33 V nominal rail requires tighter margin | Choose when system nominal voltage is 33 V and clamping headroom must exceed 5 V without exceeding 55 V. |
Compared with SMBJ30AHE3/52, the 5KP30HE3/54 delivers 8.3× higher surge power and automotive qualification; versus 5KP33HE3/54, it offers lower clamping voltage (48.4 V vs. 53.3 V) at the cost of reduced standoff margin - critical for 30 V rail designs requiring strict overvoltage containment.

FAQ
What is the clamping voltage of the 5KP30HE3/54 under full-rated surge current?
The 5KP30HE3/54 clamps to a maximum of 48.4 V when subjected to its peak pulse current of 103 A (10/1000 µs waveform). This value is measured and guaranteed per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during transient events.
Is the 5KP30HE3/54 suitable for bidirectional surge protection?
No - the 5KP30HE3/54 is a unidirectional TVS diode, designed only for clamping positive transients relative to ground. For bidirectional protection (e.g., AC lines or differential data buses), a dedicated bidirectional part such as 5KP30CAHE3/54 must be used instead of the 5KP30HE3/54.
Does the 5KP30HE3/54 require a heatsink for normal operation?
No heatsink is required for transient suppression duty, as energy dissipation is brief and non-repetitive. However, for repeated surges or elevated ambient temperatures (>75 °C), PCB copper area and thermal vias should be used per Fig. 5 derating curve - the 5KP30HE3/54 is rated for 8.0 W continuous dissipation on an infinite heatsink at TL = 75 °C.
What does the "HE3" suffix indicate in 5KP30HE3/54?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes the automotive-grade version from the commercial "E3" variant (e.g., 5KP30A-E3/54), confirming enhanced reliability testing for automotive applications.
Can the 5KP30HE3/54 replace a fuse or circuit breaker in overcurrent protection?
No - the 5KP30HE3/54 is a voltage-clamping device, not a current-interrupting element. It works alongside fuses and breakers by limiting overvoltage during surge events, allowing downstream protection devices time to operate. Per Vishay application notes, it may replace crowbar circuits but not primary overcurrent protection.
