Product details
Overview
5KP30-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping on DC power rails and signal lines. It features 30 V stand-off voltage (VWM), 33.3–36.8 V breakdown voltage (VBR) at 50 mA, 48.4 V maximum clamping voltage at 103 A peak pulse current, and 5000 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive power supplies and industrial control systems.
For engineers reviewing the 5KP30-E3/73 datasheet, 5KP30-E3/73 pinout, 5KP30-E3/73 application, or 5KP30-E3/73 equivalent, key selection criteria include its unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, low incremental surge resistance, and compatibility with J-STD-002 solderability standards for high-reliability board assembly.
Technical Context
This TVS diode operates as a voltage-clamped crowbar element during transients, leveraging a glass-passivated P600 chip junction to achieve fast response (<1 ns) and stable clamping under repetitive 0.01% duty cycle surges. Its unidirectional architecture enables integration into DC-biased circuits without reverse leakage concerns beyond 2.0 µA at 30 V.
The device sustains 103 A peak pulse current (IPPM) at 48.4 V clamping while dissipating up to 8.0 W continuously on an infinite heatsink at 75 °C lead temperature. Thermal derating follows a defined curve down to zero power at 175 °C junction temperature, supporting operation in under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 30.0 V - Maximum continuous reverse voltage before clamping begins; sets operating margin above nominal 24 V rail. |
| VBR (Breakdown Voltage) | 33.3–36.8 V at 50 mA - Confirmed avalanche onset range; ensures reliable triggering before downstream component damage. |
| VC (Clamping Voltage) | 48.4 V at 103 A - Peak voltage seen by protected circuit during 10/1000 µs surge; defines safe overvoltage ceiling. |
| PPPM (Peak Pulse Power) | 5000 W - Sustained energy absorption capability per JEDEC-standard 10/1000 µs waveform. |
| ID (Reverse Leakage) | ≤2.0 µA at 30 V - Minimal standby power loss and signal integrity impact in always-on systems. |
| TJ max | 175 °C - Enables use in high-temperature engine compartments and industrial enclosures without thermal shutdown. |
| Polarity | Unidirectional - Requires correct cathode orientation; color band denotes cathode for PCB layout verification. |
Pinout & Package
5KP30-E3/73 uses the industry-standard P600 axial-leaded package: molded epoxy body with matte tin-plated leads, UL 94 V-0 rated, 9.5 mm body length, 0.375" (9.5 mm) lead spacing, and 2.776 g unit weight. Leads are solderable per J-STD-002 and JESD 22-B102, with E3 suffix meeting JESD 201 Class 1A whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; establishes forward conduction path during positive transients. |
| Cathode | High-side surge input terminal | Marked by color band; connects to protected line (e.g., 24 V supply); conducts avalanche current to ground when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and chassis applications per stress test requirements including HTOL, TC, and UHAST. |
| 5000 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV line-earth) without degradation when properly mounted on thermal mass. |
| Fast response time | <1 ns turn-on delay ensures clamping occurs before sensitive MOSFET gate oxide or logic IC inputs experience overstress. |
| Low incremental surge resistance | Minimizes voltage overshoot during high di/dt events, improving clamping precision versus competing TVS devices. |
| RoHS-compliant & halogen-free | Meets JEDEC JS709A and EU Directive 2011/65/EU; suitable for green manufacturing and export compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ30A | Lower peak power (400 W), SMA package (surface-mount), 43.5 V clamping at 9.8 A IPPM. | Not suitable for 5000 W IEC 61000-4-5 Level 4; limited to low-energy signal-line protection. | Select only for space-constrained PCBs where surge energy is ≤500 W and clamping voltage margin allows 43.5 V. |
| ON Semiconductor 1.5KE30A | Same P600 package, 5000 W rating, but higher clamping voltage (53.3 V at 93.8 A) and no AEC-Q101 qualification. | Lacks automotive qualification; requires additional validation for under-hood deployment. | Acceptable for industrial AC/DC supplies where AEC-Q101 is not mandated and 53.3 V clamping is within system tolerance. |
Compared with SMAJ30A and 1.5KE30A, the 5KP30-E3/73 delivers superior energy handling (5000 W), lower clamping (48.4 V), and automotive-grade reliability - making it the preferred choice for high-power, safety-critical DC rail protection where thermal mass and leaded mounting are acceptable.

FAQ
What is the clamping voltage of the 5KP30-E3/73 under standard surge conditions?
The 5KP30-E3/73 exhibits a maximum clamping voltage (VC) of 48.4 V when subjected to its rated 103 A peak pulse current with a 10/1000 µs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during transient events. The 5KP30-E3/73 maintains this clamping performance across its specified operating temperature range and is validated for repetitive surge duty cycles up to 0.01%.
Is the 5KP30-E3/73 suitable for automotive applications?
Yes, the 5KP30-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 verified performance under HTOL and temperature cycling make it appropriate for protecting ECUs, body control modules, and power distribution units. The 5KP30-E3/73 meets requirements for load dump and ISO 7637-2 pulse testing when implemented with adequate PCB copper pour for thermal dissipation.
How does the 5KP30-E3/73 differ from the 5KP30A variant?
The 5KP30-E3/73 is a specific tape-and-reel packaging variant of the 5KP30A base device, with E3 denoting RoHS-compliant, commercial-grade construction and /73 indicating a 73-mm reel diameter and 800-unit quantity. Electrically and thermally, the 5KP30-E3/73 is identical to 5KP30A - same VWM (30 V), VBR (33.3–36.8 V), VC (48.4 V), and PPPM (5000 W). The 5KP30-E3/73 also shares the same P600 package outline and AEC-Q101 qualification status as the HE3 automotive-grade version.
What is the reverse leakage current specification for the 5KP30-E3/73?
The 5KP30-E3/73 has a maximum reverse leakage current (ID) of 2.0 µA at its rated stand-off voltage of 30 V and ambient temperature of 25 °C. This low leakage ensures minimal power loss in always-on systems and preserves signal integrity on protected lines. Leakage remains within specification up to 125 °C junction temperature, with typical values below 1.0 µA at room temperature - critical for battery-powered or energy-sensitive applications.
Can the 5KP30-E3/73 be used in bidirectional configurations?
No, the 5KP30-E3/73 is strictly unidirectional and must be installed with correct polarity - cathode toward the protected line and anode to ground. It does not provide symmetrical clamping for AC or bipolar transients. For bidirectional protection, two 5KP30-E3/73 devices may be connected in series opposing configuration, but this increases cost and footprint versus purpose-built bidirectional TVS devices like the 5KP30CA. The 5KP30-E3/73 datasheet explicitly states "available in uni-directional polarity only".
