Product details
Overview
5KP30AHE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on DC power rails and signal lines. It features 30 V stand-off voltage (VWM), 33.3–36.8 V breakdown voltage (VBR) at 5 mA, 48.4 V clamping voltage (VC) at 103 A peak pulse current, and 5000 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the 5KP30AHE3/54 datasheet, 5KP30AHE3/54 pinout, 5KP30AHE3/54 application, or 5KP30AHE3/54 equivalent, key selection criteria include clamping performance under 103 A surge, AEC-Q101 qualification for automotive use, unidirectional polarity, and P600 package thermal handling per JESD 22-B106 soldering specs.
Technical Context
The 5KP30AHE3/54 operates as a silicon avalanche diode with glass-passivated P600 chip junction, enabling fast response to transients (<1 ns) and low incremental surge resistance. Its unidirectional structure provides reverse-biased clamping only - forward conduction occurs above ~3.5 V at 100 A, limiting use to DC-biased protection paths.
Rated for -55 °C to +175 °C junction temperature, it supports derated operation up to 175 °C ambient when mounted on adequate heatsinking per Fig. 5. The device meets AEC-Q101 stress testing requirements and is RoHS compliant with HE3 whisker-resistant plating (JESD 201 Class 2).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin. |
| VBR min/max | 33.3 V / 36.8 V at 5 mA - Tight breakdown tolerance ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 48.4 V at 103 A - Clamping voltage limits downstream component stress during 10/1000 μs surge. |
| PPPM | 5000 W - Peak pulse power handling capability with standard 10/1000 μs waveform at 0.01% duty cycle. |
| ID @ VWM | 2.0 μA - Low leakage preserves efficiency in high-impedance bias networks and battery-powered systems. |
| TJ max | +175 °C - Enables use in under-hood automotive environments and industrial power supplies with elevated ambient temps. |
| Polarity | Unidirectional - Cathode marked by color band; suitable for DC rail protection where reverse polarity is not expected. |
Pinout & Package
Package: P600 molded epoxy case with glass-passivated junction, UL 94 V-0 rated, matte tin-plated leads solderable per J-STD-002/JESD 22-B102, 2.776 g unit weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection in clamping configuration | Connected to ground or low-impedance return path; carries full surge current during transient. |
| Cathode | High-side connection; marked by color band | Connected to protected line (e.g., 24 V rail); reverse-biased during normal operation, avalanches during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling per JEDEC standards. |
| 5000 W peak pulse power | Withstands high-energy lightning-induced surges (IEC 61000-4-5 Level 4) without failure when properly mounted. |
| Fast response time | Sub-nanosecond avalanche turn-on minimizes voltage overshoot before clamping engages. |
| Low incremental surge resistance | Reduces dynamic impedance during clamping, improving VC consistency across varying surge amplitudes. |
| JESD 201 Class 2 whisker resistance | HE3 suffix ensures long-term reliability in high-humidity, high-temperature storage and operation. |
Applications
| Automotive Power Rail Protection | Industrial DC Power Supply Output |
|---|---|
Use Scenario: Protecting 24 V battery-fed ECUs against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp transients above 30 V. Use Value: Limits voltage seen by downstream regulators and microcontrollers to ≤48.4 V during 103 A surges, preventing latch-up or permanent damage. | Use Scenario: Safeguarding output of 36 V switching power supply feeding PLC I/O modules. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing inductive kickback from relay coils and motor drivers. Use Value: Maintains system uptime by allowing fuse/breaker coordination - clamps without shorting, enabling reset after fault clearance. |
| Telecom Line Interface Protection | Consumer Appliance Motor Drive Stage |
Use Scenario: Shielding RS-485 transceivers and Ethernet PHYs from ESD and induced surges on field wiring. IC Role / Device Role / Timing Role: Secondary-level protection after gas discharge tube (GDT), providing low-clamp backup for fast transients.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | 600 W PPPM, SMC package, lower surge current (32.4 A), same VWM/VBR range | Not rated for AEC-Q101; limited to commercial/industrial use | Select when board space is constrained and surge energy is ≤600 W. |
| 1.5KE30A | 1500 W PPPM, DO-201 package, higher VF (~4.5 V), no AEC-Q101 qualification | Limited thermal mass; unsuitable for repeated high-energy surges without heatsink | Choose for cost-sensitive, low-duty-cycle applications where 5000 W rating is unnecessary. |
Compared with SMBJ30A and 1.5KE30A, the 5KP30AHE3/54 delivers 3.3× and 3.3× higher peak pulse power respectively, supports automotive qualification, and sustains higher surge repetition due to P600 thermal mass - critical for robust front-end protection in harsh environments.

FAQ
What is the clamping voltage of the 5KP30AHE3/54 under maximum rated surge current?
The 5KP30AHE3/54 has a maximum clamping voltage (VC) of 48.4 V when subjected to its rated peak pulse current (IPPM) of 103 A using the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and guarantees that downstream circuitry will not experience voltages exceeding 48.4 V during such transient events, provided layout and grounding meet recommended practices.
Is the 5KP30AHE3/54 suitable for automotive applications?
Yes, the 5KP30AHE3/54 is AEC-Q101 qualified, meaning it has passed rigorous stress tests including high-temperature reverse bias, temperature cycling, and humidity testing required for automotive electronic components. Its P600 package, HE3 whisker-resistant plating, and -55 °C to +175 °C operating range make it appropriate for under-hood and body-control module applications.
What does the "HE3" suffix indicate in 5KP30AHE3/54?
The "HE3" suffix denotes RoHS-compliant construction with JESD 201 Class 2 whisker resistance, confirming enhanced reliability for long-term storage and operation in humid, high-temperature environments. It also indicates AEC-Q101 qualification - distinguishing it from commercial-grade "E3" variants like 5KP30A-E3/54.
Can the 5KP30AHE3/54 be used in bidirectional configurations?
No, the 5KP30AHE3/54 is unidirectional only, with cathode identified by a color band. For bidirectional protection, two devices must be connected in series opposing configuration, or a dedicated bidirectional part such as 5KP30CA should be selected - which is explicitly rated for symmetrical clamping in both polarities.
What is the maximum allowable soldering temperature for the 5KP30AHE3/54?
The 5KP30AHE3/54 supports solder dip at 275 °C maximum for 10 seconds per JESD 22-B106. Reflow profiles must comply with JEDEC J-STD-020, and lead-free reflow peak temperatures should not exceed 260 °C. Exceeding these limits risks delamination or junction damage due to thermal stress on the glass-passivated chip.
