Product details
Overview
5KP20A-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 20 V stand-off voltage (VWM), 22.2–24.5 V breakdown voltage (VBR) at 5 mA, 5000 W peak pulse power (10/1000 μs), 154 A peak pulse current (IPPM), and clamps to ≤32.4 V at rated surge. It is AEC-Q101 qualified and used in automotive power supply output protection.
For engineers reviewing the 5KP20A-E3/54 datasheet, 5KP20A-E3/54 pinout, 5KP20A-E3/54 application, or 5KP20A-E3/54 equivalent, key selection criteria include clamping voltage vs. protected device withstand level, peak pulse current capability under system-level lightning/inductive-spike stress, thermal derating above 25 °C, and compliance with AEC-Q101 for automotive deployment.
Technical Context
This TVS diode operates as a shunt-clamping overvoltage protector: it remains high-impedance below VWM (20 V), avalanches sharply at VBR (min 22.2 V), and limits transient voltage to ≤32.4 V at 154 A. Its P600 glass-passivated junction enables robust 5000 W surge handling with low incremental surge resistance and sub-nanosecond response time.
Designed for DC power rail protection-especially switching power supply outputs-it replaces crowbar circuits by sustaining high IPPM without failure while allowing upstream fuses or breakers to clear faults. Thermal performance is governed by lead temperature (TL = 75 °C max for 8.0 W dissipation) and junction temperature limits (−55 °C to +175 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 20 V - Maximum continuous reverse operating voltage before leakage exceeds 2 µA; sets upper limit of normal DC rail operation. |
| VBR @ IT=5 mA | 22.2–24.5 V - Breakdown threshold range; ensures reliable conduction onset during transients exceeding nominal rail voltage. |
| VC @ IPPM | ≤32.4 V - Clamped voltage at 154 A surge; must be below protected IC/MOSFET absolute maximum rating. |
| PPPM (10/1000 µs) | 5000 W - Peak transient energy absorption capacity; defines survivability against IEC 61000-4-5 Level 4 surges. |
| IFSM (8.3 ms) | 500 A - Non-repetitive forward surge rating; supports fault-current let-through during fuse/breaker clearing. |
| TJ max. | +175 °C - Maximum junction temperature; enables use in under-hood automotive environments with proper PCB copper area. |
| Polarity | Unidirectional - Cathode marked by band; protects against positive-going transients only; requires series blocking diode for bidirectional use. |
Pinout & Package
Package: P600 molded epoxy case with glass-passivated chip junction; RoHS-compliant matte tin-plated leads; UL 94 V-0 rated; 0.375" (9.5 mm) body length; lead diameter 0.048–0.052" (1.22–1.32 mm); intended for through-hole mounting with 275 °C solder dip (10 s max).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage return path; completes shunt path during avalanche conduction. |
| Cathode | High-side input terminal | Connected to protected line (e.g., 24 V rail); color band denotes cathode; reverse-biased during normal operation. |
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, eliminating need for multi-stage clamping networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ20A-E3/52 | Lower PPPM (600 W), smaller SMB package, same VWM (20 V), higher VC (32.4 V at 17.6 A) | Targeted for board-level signal-line protection; insufficient for 5 kV lightning surges requiring 5000 W handling | Select 5KP20A-E3/54 when system-level surge testing mandates >1 kW pulse power; choose SMBJ20A-E3/52 for space-constrained low-energy signal paths. |
| 1.5KE20A | Same VWM (20 V), lower PPPM (1500 W), DO-201 package, higher VC (34.6 V at 43.3 A) | Limited to medium-energy transients; lacks AEC-Q101 qualification and thermal robustness for automotive under-hood use | Use 1.5KE20A only in cost-sensitive commercial applications with <1.5 kW surge exposure; 5KP20A-E3/54 is required for automotive-grade 5 kW immunity. |
Compared with SMBJ20A-E3/52 and 1.5KE20A, the 5KP20A-E3/54 delivers 3.3× and 3.3× higher peak pulse power respectively, maintains identical VWM for drop-in voltage compatibility, and provides AEC-Q101 validation essential for automotive power systems-making it the sole choice for ISO 16750-2-compliant load dump protection.

FAQ
What is the clamping voltage of the 5KP20A-E3/54 at its rated peak pulse current?
The 5KP20A-E3/54 clamps to a maximum of 32.4 V when subjected to its rated peak pulse current of 154 A (10/1000 μs waveform). This value is measured across the device terminals during standardized surge testing and defines the upper voltage limit imposed on protected circuitry during transient events. The 5KP20A-E3/54 achieves this clamping performance while maintaining low incremental surge resistance, ensuring consistent protection behavior across production lots.
Is the 5KP20A-E3/54 suitable for automotive applications?
Yes, the 5KP20A-E3/54 is AEC-Q101 qualified and explicitly designed for automotive use, including engine control units, body electronics, and ADAS power modules. Its 175 °C maximum junction temperature, robust P600 package, and validated surge performance under ISO 16750-2 load dump conditions make it suitable for under-hood environments. The 5KP20A-E3/54 meets the thermal and reliability requirements mandated for automotive-grade transient suppression.
What does the "-E3/54" suffix indicate in 5KP20A-E3/54?
The "-E3" suffix denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "/54" specifies the preferred packaging code for 13-inch paper tape and reel, with a base quantity of 800 pieces per reel. This ordering format ensures traceable, standardized logistics for automated assembly. The 5KP20A-E3/54 is distinct from AEC-Q101-qualified variants (e.g., 5KP20AHE3_A), which carry additional qualification markings.
How does the 5KP20A-E3/54 differ from standard Zener diodes in surge protection?
Unlike general-purpose Zener diodes, the 5KP20A-E3/54 is optimized for high-energy transient suppression: it handles 5000 W peak pulse power (vs. typically <5 W for Zeners), exhibits faster response (<1 ns), and maintains stable clamping under extreme surge currents. Its P600 package and glass-passivated junction provide superior thermal mass and surge endurance. The 5KP20A-E3/54 is not intended for voltage regulation but exclusively for shunt-based overvoltage protection.
Can the 5KP20A-E3/54 be used in bidirectional surge protection circuits?
No, the 5KP20A-E3/54 is unidirectional only, with polarity indicated by a cathode band. For bidirectional protection, two 5KP20A-E3/54 devices must be connected in series opposition (anode-to-anode), or a dedicated bidirectional TVS such as 5KP20CA should be selected. Using a single 5KP20A-E3/54 in reverse-biased configuration will not suppress negative-going transients and may fail catastrophically if exposed to significant reverse surge energy.
