Product details
Overview
5KP11A-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping on power rails and signal lines. It features 11.0 V stand-off voltage (VWM), 12.2–13.5 V breakdown voltage (VBR) at 5 mA, 18.2 V maximum clamping voltage (VC) at 275 A peak pulse current, and 5000 W peak pulse power (10/1000 μs). It is widely used to protect MOSFETs and ICs in automotive power supplies against lightning and inductive switching transients.
For engineers reviewing the 5KP11A-E3/54 datasheet, 5KP11A-E3/54 pinout, 5KP11A-E3/54 application, or 5KP11A-E3/54 equivalent, key selection criteria include clamping voltage margin vs. protected device VDS/VDD rating, peak pulse current capability under system-level surge waveforms (e.g., ISO 7637-2 Pulse 1/2b/5a), thermal derating above 25 °C, and AEC-Q101 qualification status for automotive deployment.
Technical Context
This TVS diode employs a glass-passivated P600 chip junction optimized for low incremental surge resistance and sub-nanosecond response time. Its unidirectional polarity enables DC rail protection with minimal leakage (<10 μA at 11.0 V) and stable clamping performance across -55 °C to +175 °C operating junction temperature.
The device meets JEDEC registered electrical characteristics and is rated for 500 A non-repetitive forward surge current (8.3 ms half-sine), supporting crowbar-replacement functionality in switching power supply outputs. Its P600 package supports manual or automated through-hole assembly with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11.0 V - Maximum continuous reverse working voltage before clamping begins; sets upper limit for protected circuit DC bias. |
| VBR (min/max) | 12.2 V / 13.5 V at 5 mA - Confirmed breakdown range ensures reliable turn-on without premature conduction during normal operation. |
| VC @ IPPM | 18.2 V at 275 A - Clamping voltage under 10/1000 μs surge defines worst-case overvoltage seen by downstream components. |
| PPPM | 5000 W - Peak pulse power handling capacity determines survivability against standardized lightning surges (e.g., IEC 61000-4-5). |
| TJ max. | +175 °C - Maximum junction temperature enables use in under-hood automotive environments with minimal heatsinking. |
| Polarity | Unidirectional - Suitable for DC power line protection where reverse conduction is not required; cathode marked by band. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD per AEC-Q101 Rev G. |

Package: P600 molded epoxy case with glass-passivated junction; RoHS-compliant matte tin-plated leads; 9.5 mm body length; 0.375" (9.5 mm) lead spacing; UL 94 V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to lower-potential side of protected circuit (e.g., ground or return path); enables crowbar-like shorting during overvoltage. |
| Cathode | Current exit terminal during reverse clamping | Marked by color band; connected to higher-potential rail (e.g., +12 V battery line); conducts surge current to ground when V > VBR. |
Key Features
| Feature | Design Value |

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 SMAJ11A | Lower PPPM (400 W), smaller SMA package (0.5 W PD), 18.2 V VC at 22.5 A - not suitable for 5000 W surges. | Targeted at low-energy signal-line protection (USB, RS-485), not power-rail crowbar replacement. | Select only for space-constrained, low-power applications where 5KP11A-E3/54's P600 footprint and thermal mass are unnecessary. |
| ON Semiconductor 1.5KE11A | Same VWM (11 V), but lower PPPM (1500 W), TO-204AA (DO-201AE) package, 100 °C TJ max - lacks AEC-Q101 qualification. | Used in commercial-grade power supplies; insufficient for automotive under-hood thermal and reliability requirements. | Choose only for cost-sensitive, non-automotive designs where 5KP11A-E3/54's 5000 W rating and +175 °C operation are not required. |
Compared with SMAJ11A and 1.5KE11A, the 5KP11A-E3/54 delivers 3.3× and 3.3× higher peak pulse power respectively, operates reliably at +175 °C, and carries AEC-Q101 qualification-making it the sole option among the three for automotive load-dump protection and industrial high-energy surge suppression.

FAQ
What is the clamping voltage of the 5KP11A-E3/54 under a 10/1000 μs surge?
The 5KP11A-E3/54 has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current of 275 A under a 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that downstream components see no more than 18.2 V during surge events, provided layout inductance is minimized. The 5KP11A-E3/54 maintains this clamping performance across its full operating temperature range.
Is the 5KP11A-E3/54 suitable for automotive applications?
Yes, the 5KP11A-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its +175 °C maximum junction temperature, robust P600 package, and validated performance under load dump (ISO 7637-2 Pulse 5a) make it appropriate for protecting ECUs, body control modules, and ADAS power supplies. The 5KP11A-E3/54 meets all stress test requirements defined in AEC-Q101 Rev G.
How does the 5KP11A-E3/54 differ from the 5KP11CA variant?
The 5KP11A-E3/54 is unidirectional, while the 5KP11CA is bidirectional-meaning the 5KP11CA clamps both positive and negative transients and has no polarity marking. The 5KP11A-E3/54 offers lower leakage (<10 μA at 11 V) and is intended for DC rail protection, whereas the 5KP11CA suits AC-coupled or symmetrical signal lines. Their VBR, VC, and PPPM ratings differ slightly due to internal structure; the 5KP11A-E3/54 is not interchangeable with 5KP11CA without circuit review.
What is the thermal derating behavior of the 5KP11A-E3/54 above 25 °C?
The 5KP11A-E3/54 follows a linear derating curve: its peak pulse power capability decreases from 5000 W at 25 °C to zero at +175 °C, per Figure 2 in the Vishay datasheet (Doc. #88308). At 125 °C ambient, it retains approximately 60 % of rated PPPM. This derating must be applied when sizing for repeated surge events in high-temperature enclosures. The 5KP11A-E3/54's P600 package supports heatsinking via lead-frame conduction.
Can the 5KP11A-E3/54 replace a 1.5KE11A in an existing design?
No direct replacement is recommended. While both share 11 V VWM, the 5KP11A-E3/54 delivers 5000 W peak pulse power versus 1500 W for the 1.5KE11A, uses a larger P600 package (vs. DO-201AE), and is AEC-Q101 qualified. Swapping requires PCB layout changes, thermal analysis, and revalidation of surge immunity. The 5KP11A-E3/54 is physically and electrically incompatible as a drop-in substitute for the 1.5KE11A.
