Product details
Overview
5KP13-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection of DC power rails and signal lines. It features 13 V standoff voltage (VWM), 14.4–15.9 V breakdown voltage (VBR at 5 mA), 5000 W peak pulse power (10/1000 µs), 233 A peak pulse current (IPPM), and clamps to ≤21.5 V at rated surge. It is AEC-Q101 qualified and used in automotive power supply output protection.
For engineers reviewing the 5KP13-E3/73 datasheet, 5KP13-E3/73 pinout, 5KP13-E3/73 application, or 5KP13-E3/73 equivalent, key selection criteria include unidirectional polarity, 13 V stand-off rating, 5 kW surge capability, P600 through-hole package compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode employs a glass-passivated P600 chip junction optimized for fast response (<1 ps) and low incremental surge resistance. Its unidirectional architecture provides forward conduction only during overvoltage events on the cathode-biased side, enabling crowbar-style fault handling without reverse leakage concerns at normal operating voltages.
The device operates across –55 °C to +175 °C junction temperature range and supports 8.3 ms half-sine surge waveforms up to 500 A (IFSM). Its 3.5 V forward voltage at 100 A ensures minimal conduction loss during sustained overcurrent conditions, while its 0.090 %/°C VBR temperature coefficient guarantees stable clamping across thermal extremes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 14.4 V / 15.9 V at 5 mA - Confirmed breakdown threshold for reliable overvoltage triggering |
| IPPM | 233 A at 10/1000 µs - Peak surge current it safely shunts without failure |
| VC | ≤21.5 V at IPPM - Clamped voltage protecting downstream ICs from destructive overvoltage |
| PPPM | 5000 W - Peak pulse power dissipation capacity under standardized surge waveform |
| TJ max | +175 °C - Maximum junction temperature enabling operation in under-hood automotive environments |
| Leakage (ID) | ≤2.0 µA at VWM - Negligible reverse current ensuring minimal standby power loss |
Pinout & Package
5KP13-E3/73 is housed in a P600 molded epoxy package with axial leads. The cathode is marked by a color band on the body; the anode and cathode terminals are non-polarized in layout but functionally asymmetric due to unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during clamping | Connected to protected line's lower potential side (e.g., ground or return path) |
| Cathode | Reverse-biased terminal during normal operation; surge current sink during overvoltage | Connected to protected line's higher potential side (e.g., +12 V rail); color band identifies this end |
Key Features

IC Role / Device Role / Timing Role: Final-stage TVS on regulated 5 V/12 V outputs feeding USB ports and sensor interfaces. Use Value: 2.0 µA leakage at 13 V prevents standby current drain; RoHS-compliant plating meets global consumer safety standards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Lower peak power (600 W), SMC package, same VWM (13 V), smaller footprint | Suitable for space-constrained PCBs but not for automotive load dump or industrial motor drive surges | Select SMBJ13A only if surge energy is <100 mJ and board area is critical; 5KP13-E3/73 remains required for 5 kW compliance. |
| 1.5KE13A | Same P600 package, 1500 W peak power, identical VWM/VBR, lower IPPM (103 A) | Meets basic IEC 61000-4-5 Level 3 but fails ISO 7637-2 Pulse 5a testing | Choose 1.5KE13A for cost-sensitive industrial controls where full 5 kW rating is unnecessary; 5KP13-E3/73 is mandatory for AEC-Q101 automotive designs. |
Compared with SMBJ13A and 1.5KE13A, the 5KP13-E3/73 delivers 3.3× and 3.3× higher peak pulse power respectively, enabling single-device compliance with automotive load dump and heavy industrial surge standards without parallel stacking or heatsinking.

FAQ
What is the clamping voltage of the 5KP13-E3/73 under full-rated surge conditions?
The 5KP13-E3/73 clamps to a maximum of 21.5 V when subjected to its rated 233 A peak pulse current (10/1000 µs waveform). This value is measured per JEDEC test conditions and ensures downstream components like microcontrollers or gate drivers remain within safe operating voltage limits during transient events. The clamping performance is guaranteed across the full operating temperature range.
Is the 5KP13-E3/73 suitable for bidirectional surge protection applications?
No, the 5KP13-E3/73 is strictly unidirectional and must be installed with correct polarity-cathode toward the protected voltage rail. It does not provide symmetrical clamping for AC or bipolar transients. For bidirectional protection, a separate device such as the 5KP13CA or a back-to-back configuration would be required; the 5KP13-E3/73 itself functions only in one direction.
Does the 5KP13-E3/73 meet automotive qualification standards?
Yes, the 5KP13-E3/73 is AEC-Q101 qualified, as confirmed in Vishay's official documentation (Document Number 88308, Revision 20-Nov-12). This qualification validates its reliability for use in automotive electronic control units, body modules, and powertrain systems where extended temperature operation and surge immunity are mandatory.
What is the maximum continuous power dissipation of the 5KP13-E3/73 at elevated temperatures?
The 5KP13-E3/73 has a maximum steady-state power dissipation (PD) of 8.0 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C. Derating follows the curve in Figure 5 of the datasheet: at 125 °C TL, usable PD drops to approximately 4.0 W. This rating applies only to continuous DC or low-frequency dissipation-not to transient surge events.
How does the 5KP13-E3/73 compare to standard Zener diodes in surge protection roles?
Unlike general-purpose Zener diodes, the 5KP13-E3/73 is optimized for high-energy transient suppression: it offers 5000 W peak pulse power (vs. typically <5 W for Zeners), lower dynamic impedance during surges, and guaranteed clamping performance under standardized 10/1000 µs waveforms. Its P600 package and glass-passivated junction also provide superior surge endurance compared to small-signal Zener packages.
