Product details
Overview
5KP30-E3/54 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 50 mA, 48.4 V clamping voltage (VC) at 103 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs). It is widely used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the 5KP30-E3/54 datasheet, 5KP30-E3/54 pinout, 5KP30-E3/54 application, or 5KP30-E3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, P600 mechanical dimensions, clamping performance under standardized surge waveforms, and direct alternatives with documented voltage and power differences.
Technical Context
This TVS diode operates as a voltage-clamping overvoltage protector - it remains high-impedance below VWM (30 V), then rapidly avalanches above VBR to limit transient energy. Its P600 glass-passivated junction enables stable 5000 W surge handling with low incremental surge resistance and sub-nanosecond response time.
The device is rated for -55 °C to +175 °C junction temperature, supports 600 A non-repetitive forward surge (IFSM), and exhibits 0.103 %/°C VBR temperature coefficient. Its unidirectional polarity (cathode-banded) and 2.0 μA max reverse leakage at VWM make it suitable for DC-biased rail protection where reverse conduction must be blocked.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin. |
| VBR (min/max) | 33.3 V / 36.8 V at 50 mA - guaranteed avalanche onset range; ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | 48.4 V at 103 A (10/1000 μs) - clamped voltage during worst-case surge; determines protected circuit's maximum stress level. |
| PPPM | 5000 W - peak transient power dissipation capability; validates suitability for IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | ≤2.0 μA - ultra-low reverse leakage at rated stand-off; minimizes standby power loss in battery-powered systems. |
| TJ max. | +175 °C - extended thermal rating enabling use in under-hood automotive or high-ambient industrial environments. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness. |
Pinout & Package
P600 package: axial-leaded, molded epoxy body with matte tin-plated leads; meets UL 94 V-0 flammability; cathode indicated by color band; RoHS-compliant (E3 suffix); 2.776 g unit weight; supplied in 13" paper tape and reel (800 pcs per reel, code 54).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode | Current exit terminal during clamping; marked with band | Connected to higher-potential side (e.g., +30 V rail); avalanche conduction occurs when cathode-to-anode voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables single-device protection against severe lightning-induced surges per IEC 61000-4-5 without external crowbar circuitry. |
| AEC-Q101 qualification | Validates long-term reliability in automotive power modules, engine control units, and ADAS sensor power inputs. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during fast transients, reducing risk of downstream IC latch-up or gate oxide damage. |
| 175 °C max junction temperature | Supports operation in high-temperature enclosures (e.g., under-hood ECUs) without derating or heatsinking. |
| UL 94 V-0 molded epoxy case | Provides flame-retardant mechanical encapsulation essential for safety-critical industrial and transportation systems. |
Applications
| Automotive Power Rail Protection | Industrial DC Power Supply Output |

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 PPPM (400 W), smaller SMA package, same 30 V VWM and unidirectional polarity. | Not suitable for IEC 61000-4-5 Level 4; limited to board-level ESD/EFT only. | Select when space-constrained PCB layout demands SMD mounting and surge energy is ≤400 W. |
| ON Semiconductor 1.5KE30A | Same 30 V VWM and P600 package, but lower PPPM (1500 W) and higher VC (49.9 V at 30.1 A). | Cannot handle repeated 5 kA surges; requires parallel devices for equivalent energy absorption. | Choose if cost sensitivity outweighs surge margin, and system testing confirms 1500 W suffices. |
Compared with 5KP30-E3/54, SMAJ30A offers compact SMD integration but sacrifices >85 % surge power capacity, while 1.5KE30A retains axial form factor yet delivers only 30 % of the peak pulse energy handling - making 5KP30-E3/54 the sole option for high-reliability 5 kW-class protection in automotive and industrial power systems.

FAQ
What is the clamping voltage of the 5KP30-E3/54 under standard surge conditions?
The 5KP30-E3/54 has a maximum clamping voltage (VC) of 48.4 V when subjected to a 10/1000 μs waveform with a peak pulse current (IPPM) of 103 A. This value is measured per JEDEC standards and guarantees that protected circuits will not experience voltages exceeding 48.4 V during such transients, ensuring compatibility with 36 V-rated components. The 5KP30-E3/54 maintains this performance across its full operating temperature range.
Is the 5KP30-E3/54 suitable for automotive applications?
Yes, the 5KP30-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS power domains. Its 175 °C maximum junction temperature, robust P600 package, and validated performance under temperature cycling and humidity testing meet automotive reliability requirements. The 5KP30-E3/54 is explicitly referenced in Vishay's automotive-grade TVS documentation.
What does the "E3/54" suffix mean in 5KP30-E3/54?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "54" denotes the preferred package code for 13-inch paper tape and reel packaging containing 800 units. This ordering format aligns with Vishay's standardized part numbering for P600 TVS diodes and ensures correct material compliance and logistics handling for the 5KP30-E3/54.
How does the 5KP30-E3/54 differ from the 5KP30A variant?
The 5KP30-E3/54 is the RoHS-compliant, tape-and-reel packaged version of the 5KP30A base device. Electrically and thermally identical, the 5KP30-E3/54 adds JESD 201 Class 1A whisker resistance and conforms to UL 94 V-0 flammability - critical for high-reliability production. The "HE3" variant would indicate AEC-Q101 qualification, whereas "E3" denotes commercial grade; both share identical 5KP30-E3/54 VWM, VBR, and VC specs.
Can the 5KP30-E3/54 be used in bidirectional configurations?
No, the 5KP30-E3/54 is strictly unidirectional, with polarity marked by a cathode band. It conducts only when cathode voltage exceeds anode voltage by ≥VBR - making it unsuitable for AC line or bidirectional signal protection. For symmetrical surge suppression, two 5KP30-E3/54 devices must be connected in series opposition, or a dedicated bidirectional TVS like 5KP30CA should be selected instead.
