Product details
Overview
5KP16A-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 16.0 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR) at 5.0 mA, 5000 W peak pulse power (10/1000 μs), and clamps transients to ≤26.0 V at 192 A peak pulse current - deployed in automotive power supplies and industrial sensor interfaces.
For engineers reviewing the 5KP16A-E3/51 datasheet, 5KP16A-E3/51 pinout, 5KP16A-E3/51 application, or 5KP16A-E3/51 equivalent, this page delivers verified electrical parameters, P600 package details, AEC-Q101 qualification status, clamping performance under surge conditions, and direct alternative part comparisons for overvoltage protection design validation.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, activated when reverse voltage exceeds VBR (17.8–19.7 V), diverting surge current away from protected circuitry while maintaining low dynamic impedance. Its glass-passivated P600 junction enables stable operation up to 175 °C junction temperature and supports repetitive 0.01% duty cycle surges.
Designed for DC rail protection, it replaces crowbar circuits by withstanding 5000 W pulses without failure, allowing upstream fuses or breakers time to clear faults. The 2.0 μA max reverse leakage at 16.0 V ensures minimal standby power loss in always-on systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 16.0 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 17.8–19.7 V at 5.0 mA - Avalanche onset range; ensures reliable triggering above normal operating voltage. |
| VC (Clamping Voltage) | ≤26.0 V at 192 A (10/1000 μs) - Peak voltage seen by protected IC during worst-case surge; limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 5000 W - Energy-handling capacity per transient; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity designs. |
| IPPM (Peak Pulse Current) | 192 A - Maximum non-repetitive surge current the device safely clamps; determines minimum fuse/breaker coordination. |
| TJmax | 175 °C - Maximum junction temperature; enables use in under-hood automotive environments and high-ambient industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; suitable for ASIL-B system protection. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; RoHS-compliant, UL 94 V-0 rated; cathode denoted by color band. Lead finish meets J-STD-002 and JESD 22-B102 solderability standards; qualified per JESD 201 Class 1A whisker test (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path / Surge return path | Connected to ground or low-impedance return; completes clamping loop during transient events. |
| Cathode | Protected line connection / High-side clamp node | Connected to the line being protected (e.g., 12 V battery rail); 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. |
| Low clamping ratio (VC/VBR ≈ 1.35) | Minimizes overvoltage overshoot during fast transients, reducing risk of latch-up or gate oxide damage in protected MOSFETs and ICs. |
| AEC-Q101 qualification | Validates robustness across automotive temperature (-55 °C to +175 °C), vibration, and humidity stress profiles for engine control and ADAS modules. |
| Uni-directional polarity only | Simplifies layout and selection for DC applications where reverse polarity protection is handled separately; avoids ambiguity in bidirectional clamping behavior. |
| 175 °C maximum junction temperature | Supports placement near heat-generating components (e.g., power converters) without derating, improving system-level thermal management flexibility. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Lower peak power (600 W), smaller SMB package, same VWM (16 V), higher VC (26.0 V → 28.8 V at 21.2 A) | Targeted at board-level signal line protection, not high-energy DC rail clamping | Select SMBJ16A only for space-constrained, lower-energy applications where 5000 W capability is unnecessary. |
| 1.5KE16A | Same P600 package, lower peak power (1500 W), identical VWM/VBR, higher VC (28.0 V at 53.5 A) | Legacy industrial use; lacks AEC-Q101 qualification and modern surge endurance | Choose 1.5KE16A only for cost-sensitive, non-automotive applications with moderate surge exposure. |
Compared with SMBJ16A and 1.5KE16A, the 5KP16A-E3/51 delivers 3.3× higher peak pulse power than 1.5KE16A and 8.3× more than SMBJ16A - enabling single-device compliance with IEC 61000-4-5 Level 4 in high-reliability automotive and industrial power systems.

FAQ
What is the clamping voltage of the 5KP16A-E3/51 under a 10/1000 μs surge?
The 5KP16A-E3/51 clamps to a maximum of 26.0 V when subjected to its rated peak pulse current of 192 A using the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and reflects worst-case voltage seen by protected circuitry during surge events, ensuring compatibility with 24 V system components.
Is the 5KP16A-E3/51 suitable for automotive applications?
Yes, the 5KP16A-E3/51 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C, making it suitable for under-hood and chassis-mounted automotive applications including engine control units, body control modules, and ADAS power supplies where load dump and ISO 7637-2 pulse immunity are required.
What does the "E3/51" suffix indicate in 5KP16A-E3/51?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "/51" specifies the packaging configuration - 51 indicates 800-piece tape-and-reel delivery in 13-inch diameter reels, per Vishay's ordering convention for P600 devices.
How does the 5KP16A-E3/51 differ from bidirectional TVS diodes?
The 5KP16A-E3/51 is unidirectional only, meaning it functions as a reverse-biased Zener clamp for DC lines with defined polarity. Unlike bidirectional variants, it does not conduct in forward bias beyond ~3.5 V, making it inappropriate for AC line protection but optimal for stable DC rail clamping with minimal leakage.
Can the 5KP16A-E3/51 replace older 1.5KE-series TVS diodes?
The 5KP16A-E3/51 offers significantly higher surge capability (5000 W vs. 1500 W for 1.5KE16A) and tighter clamping (26.0 V vs. 28.0 V), but is not a drop-in replacement due to differences in thermal dissipation and PCB footprint requirements. Layout review and thermal validation are required before substitution.
