Product details
Overview
5KP13A-E3/51 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal paths. It features a 13.0 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 5.0 mA, 21.5 V clamping voltage (VC) at 233 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs). It is used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the 5KP13A-E3/51 datasheet, 5KP13A-E3/51 pinout, 5KP13A-E3/51 application, or 5KP13A-E3/51 equivalent, key selection criteria include clamping voltage margin relative to protected device VDS/VCC, peak pulse current capability under system-level surge waveforms, thermal derating above 25 °C, and AEC-Q101 qualification status for automotive deployment.
Technical Context
This TVS diode employs a glass-passivated P600 package with a unidirectional junction optimized for fast response (<1 ns) to transients induced by inductive load switching or lightning surges. Its low incremental surge resistance ensures minimal voltage overshoot during 10/1000 μs waveform events.
The device operates within –55 °C to +175 °C junction temperature range and supports repetitive surge duty cycles up to 0.01 %, with 8.0 W steady-state power dissipation on an infinite heatsink at 75 °C lead temperature. It meets JESD 22-B106 solderability and JESD 201 class 1A whisker testing requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13.0 V - Maximum continuous reverse operating voltage before conduction begins; sets upper limit for normal circuit operation. |
| VBR min/max | 14.4 V / 15.9 V at 5.0 mA - Confirmed breakdown threshold range; ensures reliable turn-on before protected device overvoltage. |
| VC @ IPPM | 21.5 V at 233 A - Clamped voltage during 5000 W transient; defines worst-case stress on downstream components. |
| PPPM | 5000 W (10/1000 μs) - Peak surge energy handling capacity; validates suitability for IEC 61000-4-5 Level 4 compliance designs. |
| TJ max | +175 °C - Maximum junction temperature; enables use in under-hood automotive environments with minimal thermal margin loss. |
| Polarity | Unidirectional - Cathode marked by color band; requires correct orientation in series with positive rail or across DC bus. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC standard. |
Pinout & Package
5KP13A-E3/51 is housed in a P600 axial-leaded package with matte tin-plated leads. The cathode is identified by a colored band on one end; the opposite end is the anode. Leads are compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Current entry point during forward conduction; connected to lower-potential side of protected circuit | Must be tied to ground or negative rail when protecting positive supply lines; determines polarity-specific placement. |
| Cathode (banded end) | Current exit point during reverse avalanche; connected to higher-potential side of protected circuit | Placed on input/power rail side; clamps transients by shunting surge current to ground through this terminal. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables robust protection against severe lightning-induced surges without degradation in automotive and industrial mains-connected systems. |
| AEC-Q101 qualification | Validates long-term reliability under automotive thermal, vibration, and humidity stress profiles-no additional qualification required for Tier 1 programs. |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes overvoltage exposure to sensitive downstream ICs while maintaining sufficient margin above VWM to avoid false triggering. |
| P600 glass-passivated junction | Provides stable electrical characteristics over lifetime and immunity to moisture ingress-critical for outdoor or under-hood applications. |
| 175 °C max junction temperature | Supports operation in high-ambient environments such as engine control units and industrial motor drives without thermal shutdown. |
Applications
| Automotive Power Supply Protection | Industrial DC Bus Clamping |

IC Role / Device Role / Timing Role: Final-line TVS positioned immediately before connector to suppress conducted noise entering host device. Use Value: Withstands 5000 W pulses without parameter shift, enabling single-device protection architecture instead of cascaded TVS+capacitor solutions. |
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 SMAJ13A | Lower PPPM (400 W vs. 5000 W); SMA package (surface-mount); 13.0 V VWM; 21.5 V VC @ 17.4 A | Suitable only for low-energy board-level ESD, not for system-level lightning or load dump. | Select 5KP13A-E3/51 when surge current exceeds 100 A or when axial-leaded through-hole mounting is required. |
| ON Semiconductor 1.5KE13A | Same VWM (13 V), but lower PPPM (1500 W); DO-201 package; 21.2 V VC @ 71 A; not AEC-Q101 qualified | Lacks automotive qualification and thermal robustness for under-hood deployment. | Choose 5KP13A-E3/51 for AEC-Q101-compliant designs requiring >3× peak power handling and extended temperature operation. |
Compared with SMAJ13A and 1.5KE13A, the 5KP13A-E3/51 delivers 3.3× and 3.3× higher peak pulse power respectively, maintains AEC-Q101 qualification, and supports sustained operation up to +175 °C-making it the only option among the three validated for automotive load dump and industrial 24 V DC bus protection.

FAQ
What is the maximum clamping voltage of the 5KP13A-E3/51 under full-rated surge conditions?
The 5KP13A-E3/51 exhibits a maximum clamping voltage (VC) of 21.5 V when subjected to its rated peak pulse current of 233 A (10/1000 μs waveform). This value is measured and guaranteed per JEDEC registered test conditions in the Vishay datasheet document 88308, ensuring predictable overvoltage limiting during real-world transients.
Is the 5KP13A-E3/51 suitable for automotive applications?
Yes, the 5KP13A-E3/51 is AEC-Q101 qualified and explicitly rated for automotive use. Its –55 °C to +175 °C operating junction temperature range, robust P600 package, and validated performance under load dump and ISO 7637-2 pulse conditions make it appropriate for engine control units, body electronics, and ADAS power domains.
What does the "E3/51" suffix indicate in 5KP13A-E3/51?
The "E3" denotes RoHS-compliant, commercial-grade termination meeting JESD 201 class 1A whisker testing, while "/51" specifies the preferred packaging code: 500-piece bulk pack in ammo pack format. This differs from tape-and-reel variants like /54, and confirms lead finish, environmental compliance, and delivery mode per Vishay ordering information.
How does the 5KP13A-E3/51 compare to bidirectional TVS diodes?
The 5KP13A-E3/51 is unidirectional and intended for DC line protection where polarity is fixed-such as 12 V or 24 V power rails. Unlike bidirectional types, it blocks reverse leakage more effectively below VWM and offers tighter clamping symmetry in forward conduction, but cannot protect AC signals or floating buses without external biasing.
Can the 5KP13A-E3/51 replace older 1.5KE-series TVS diodes?
No direct replacement: the 5KP13A-E3/51 delivers 3.3× higher peak pulse power (5000 W vs. 1500 W) and uses a larger P600 package versus DO-201. While both share 13 V VWM, PCB layout, thermal management, and surge coordination must be re-evaluated-especially for sustained surge repetition or elevated ambient temperatures.
