Product details
Overview
5KP11A-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 11.0 V stand-off voltage (VWM), 12.2–13.5 V breakdown voltage (VBR) at 5.0 mA, and clamps to ≤18.2 V at 275 A peak pulse current (10/1000 μs), delivering 5000 W peak pulse power.
For engineers reviewing the 5KP11A-E3/73 datasheet, 5KP11A-E3/73 pinout, 5KP11A-E3/73 application, or 5KP11A-E3/73 equivalent, this device is selected for high-energy surge suppression in automotive power supplies, industrial motor drives, and telecom DC-DC converter outputs where fast response (<1 ns), low clamping ratio, and AEC-Q101 qualification are required.
Technical Context
This TVS diode operates as a voltage-clamped crowbar element in parallel with protected circuitry, triggering into avalanche conduction when reverse voltage exceeds VBR. Its glass-passivated P600 junction enables stable 5000 W surge handling under 10/1000 μs waveform with 0.01% duty cycle.
It exhibits 10 μA max reverse leakage at 11.0 V, 3.5 V forward voltage at 100 A, and thermal derating down to zero power at 175 °C junction temperature. The cathode band denotes polarity, and matte tin-plated leads comply with J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11.0 V - Maximum continuous reverse operating voltage before significant leakage begins; sets upper limit for normal DC rail operation. |
| VBR (min/max) | 12.2 V / 13.5 V at 5.0 mA - Confirmed avalanche onset range; ensures reliable triggering above system nominal voltage. |
| VC @ IPPM | ≤18.2 V at 275 A - Clamped voltage during full-rated 5000 W transient; determines maximum stress on downstream ICs. |
| PPPM | 5000 W - Peak pulse power rating with 10/1000 μs waveform; defines single-event surge energy absorption capability. |
| IFSM | 600 A - Non-repetitive forward surge current (8.3 ms half-sine); supports crowbar-style fault clearing without fuse blow delay. |
| TJ max | +175 °C - Maximum junction temperature; enables use in under-hood automotive and high-ambient industrial environments. |
| Package | P600 - Axial-leaded, molded epoxy case rated UL 94 V-0; provides mechanical robustness and thermal path via leadframe. |
Pinout & Package
P600 package: axial-leaded, cylindrical epoxy body with cathode band marking; leads are matte tin-plated, solderable per J-STD-002; body meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A | Lower peak power (600 W), SMC package, same VWM/VBR tolerance but higher VC/IPPM ratio (20.0 V @ 30 A). | Best suited for PCB space-constrained, lower-energy applications like USB port or sensor interface protection-not for load dump. | Select SMBJ11A only when surge energy is ≤600 W and board layout prohibits axial P600 mounting. |
| 1.5KE11A | Same P600 package and 5000 W rating, but older JEDEC-standard part with wider VBR tolerance (12.2–14.6 V) and no AEC-Q101 qualification. | Acceptable for industrial/commercial use where automotive qualification is not mandated; lacks automotive traceability. | Choose 1.5KE11A if AEC-Q101 is unnecessary and legacy BOM compatibility is prioritized over modern reliability testing. |
Compared with SMBJ11A and 1.5KE11A, the 5KP11A-E3/73 delivers superior surge robustness in automotive-grade form factor-its tighter VBR spread, lower clamping voltage, and AEC-Q101 validation make it the preferred choice for safety-critical 12 V systems requiring long-term field reliability.

FAQ
What is the maximum clamping voltage of the 5KP11A-E3/73 under full-rated surge conditions?
The 5KP11A-E3/73 clamps to a maximum of 18.2 V when subjected to its rated 275 A peak pulse current (10/1000 μs waveform). This value is measured per JEDEC test conditions and represents the highest voltage seen across the device during worst-case transient events. It directly determines the peak stress imposed on downstream components, making it a critical parameter for system-level overvoltage margin analysis in the 5KP11A-E3/73 design.
Is the 5KP11A-E3/73 suitable for automotive applications?
Yes, the 5KP11A-E3/73 is AEC-Q101 qualified and explicitly rated for automotive under-hood use, including engine control modules and body electronics exposed to ISO 7637-2 load dump transients. Its P600 package, 175 °C max junction temperature, and RoHS-compliant E3 termination meet automotive manufacturing and reliability requirements. The 5KP11A-E3/73 data sheet confirms qualification per AEC-Q101 test conditions.
How does the 5KP11A-E3/73 differ from the 1.5KE11A in practical design use?
The 5KP11A-E3/73 offers tighter VBR tolerance (12.2–13.5 V vs. 12.2–14.6 V), lower clamping voltage (18.2 V vs. ~19.5 V), and formal AEC-Q101 qualification-unlike the legacy 1.5KE11A. Both share P600 packaging and 5000 W rating, but the 5KP11A-E3/73 provides improved consistency and automotive traceability. For new designs targeting automotive or high-reliability industrial use, the 5KP11A-E3/73 is the recommended replacement.
What is the reverse leakage current specification for the 5KP11A-E3/73 at its stand-off voltage?
At its 11.0 V stand-off voltage (VWM), the 5KP11A-E3/73 exhibits a maximum reverse leakage current (ID) of 10 μA at 25 °C. This low leakage ensures minimal standby power loss and avoids false triggering in precision voltage monitoring circuits. The value is confirmed in the "ELECTRICAL CHARACTERISTICS" table of the Vishay 88308 datasheet for the 5KP11A-E3/73 device.
Can the 5KP11A-E3/73 be used in bidirectional configurations?
No, the 5KP11A-E3/73 is unidirectional only, as stated in the Vishay datasheet "FEATURES" section. It conducts in reverse avalanche mode above VBR but blocks forward current beyond its 3.5 V forward voltage at 100 A. For bidirectional protection, two 5KP11A-E3/73 devices must be connected in series opposition-or a dedicated bidirectional TVS such as the 5KP11CA should be selected instead.
