Product details
Overview
5KP30A-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 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 5KP30A-E3/54 datasheet, 5KP30A-E3/54 pinout, 5KP30A-E3/54 application, or 5KP30A-E3/54 equivalent, this device is selected for robust overvoltage protection in automotive power supplies, industrial motor drives, and telecom DC input stages where fast response (<1 ns), low clamping ratio, and AEC-Q101 qualification are critical.
Technical Context
The 5KP30A-E3/54 employs a glass-passivated P600 junction optimized for non-repetitive surge handling up to 5000 W. Its unidirectional polarity enables use in DC-biased circuits requiring cathode-to-rail configuration, with clamping action triggered only during reverse overvoltage events.
It operates within -55 °C to +175 °C junction temperature range and supports 500 A peak forward surge current (IFSM) at 8.3 ms half-sine. Thermal derating follows a defined curve above 25 °C ambient, requiring appropriate PCB copper area or heatsinking for sustained power dissipation beyond 8.0 W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 30.0 V - Maximum continuous reverse voltage before leakage exceeds 2 μA; defines safe operating DC bias level. |
| VBR (Breakdown Voltage) | 33.3–36.8 V at 5 mA - Confirmed avalanche initiation range; ensures predictable turn-on under transients. |
| VC (Clamping Voltage) | 48.4 V at 103 A - Peak voltage seen by protected circuit during 10/1000 μs surge; limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 5000 W - Energy-handling capacity for single 10/1000 μs surges; validates suitability for lightning and inductive-switching threats. |
| IFSM (Surge Current) | 500 A at 8.3 ms - Withstands short-duration forward surges without failure; supports crowbar-replacement designs. |
| TJ max. | +175 °C - Enables operation in under-hood automotive or high-temperature industrial enclosures without thermal shutdown. |
| Polarity | Unidirectional - Requires cathode connection to higher-potential rail; not suitable for AC or bidirectional line protection. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 rated; cathode indicated by color band. Lead finish complies with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lower-potential node; carries full surge current during clamping. |
| Cathode | High-side surge input terminal | Marked by color band; connected to protected line; voltage clamps relative to anode when exceeded. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan. |
| 5000 W peak pulse power | Handles IEC 61000-4-5 Level 4 (4 kV) surges without degradation when properly mounted on ≥1 in² copper area. |
| Fast response time | <1 ns turn-on delay ensures clamping occurs before sensitive ICs experience overvoltage damage. |
| Low incremental surge resistance | Minimizes voltage overshoot during rapid di/dt events; improves clamping consistency across surge amplitudes. |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance; suitable for lead-free reflow and long-term storage stability. |
Applications
| Automotive Power Supply Protection | Industrial Motor Drive DC Bus |
|---|---|
Use Scenario: Protecting 24 V battery-fed ECUs against load dump (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role / Timing Role: Primary TVS clamp on main input rail, placed upstream of DC/DC converters and microcontrollers. Use Value: Clamps to 48.4 V at 103 A, limiting voltage stress below 50 V threshold of most 3.3 V/5 V regulators and CAN transceivers. |
Use Scenario: Safeguarding IGBT gate drivers and bus capacitors from switching-induced voltage spikes in 400 V DC drives. IC Role / Device Role / Timing Role: Parallel-mounted across DC link to absorb inductive kickback energy during IGBT turn-off. Use Value: Absorbs 5000 W pulses without thermal runaway, enabling fuse coordination and eliminating need for crowbar SCR circuits. |
| Telecom DC Input Stage | Consumer Power Adapter Output |
Use Scenario: Securing PoE-powered equipment inputs against induced surges from outdoor cabling and lightning coupling. IC Role / Device Role / Timing Role: Secondary-level TVS after primary MOV, providing precise clamping for IEEE 802.3bt-compliant 57 V systems. Use Value: 30 V VWM allows clean operation at nominal 57 V with margin; 48.4 V VC prevents latch-up in Ethernet PHYs and PMICs. |
Use Scenario: Overvoltage suppression on 12 V/19 V outputs of laptop adapters exposed to accidental mains coupling or capacitor discharge. IC Role / Device Role / Timing Role: Final-stage protection before USB-C PD controllers and battery management ICs. Use Value: Unidirectional configuration avoids reverse conduction losses; 175 °C TJ max supports compact enclosure thermal design. |
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, 43.5 V VC at 92.6 A | Suitable for lower-energy surges; limited to PCB space-constrained consumer designs | Select 5KP30A-E3/54 when >1000 W surge capability or automotive qualification is required. |
| ON Semiconductor 1.5KE30A | Same VWM/VBR range but 1500 W PPPM, DO-201 package, 49.9 V VC at 30.1 A | Lower energy handling; used in legacy industrial controls with existing DO-201 footprints | Choose 5KP30A-E3/54 for new designs needing 3.3× higher surge margin and AEC-Q101 compliance. |
Compared with SMAJ30A and 1.5KE30A, the 5KP30A-E3/54 delivers 3.3× and 3.3× higher peak pulse power respectively, maintains tighter clamping (48.4 V vs. 43.5 V/49.9 V), and is the only AEC-Q101-qualified option-making it the preferred choice for automotive and high-reliability industrial deployments.

FAQ
What is the clamping voltage of the 5KP30A-E3/54 under standard test conditions?
The 5KP30A-E3/54 has a maximum clamping voltage (VC) of 48.4 V when subjected to a 10/1000 μs waveform with 103 A peak pulse current. This value is measured per JEDEC standards and reflects the actual voltage imposed on protected circuitry during surge events, ensuring compatibility with 48 V-rated components and interfaces.
Is the 5KP30A-E3/54 qualified for automotive applications?
Yes, the 5KP30A-E3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing. This makes the 5KP30A-E3/54 suitable for under-hood and body-control module applications where reliability under thermal and electrical stress is mandatory.
What does the "E3/54" suffix indicate in 5KP30A-E3/54?
The "E3" suffix denotes RoHS-compliant matte tin plating meeting JESD 201 Class 1A whisker resistance, while "/54" specifies the preferred packaging code: 13-inch diameter paper tape and reel containing 800 units. This packaging format supports automated SMT placement and ensures consistent moisture sensitivity level (MSL) handling.
Can the 5KP30A-E3/54 be used in bidirectional protection circuits?
No, the 5KP30A-E3/54 is unidirectional only, with polarity marked by a cathode band. It conducts only during reverse-biased overvoltage events. For AC or bidirectional line protection, a pair of 5KP30A-E3/54 devices in series-opposing configuration-or a dedicated bidirectional TVS like 5KP30CA-is required.
What thermal considerations apply when mounting the 5KP30A-E3/54?
The 5KP30A-E3/54 dissipates up to 8.0 W on an infinite heatsink at TL = 75 °C, but derates linearly above 25 °C ambient. Effective thermal management requires ≥1 in² (6.5 cm²) of 2 oz copper on the anode/cathode pads, and adherence to the power derating curve in Figure 5 to avoid exceeding 175 °C junction temperature during repeated surges.
