Product details

Overview

5KP16A-E3/54 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 mA, 5000 W peak pulse power (10/1000 μs), 192 A peak pulse current (IPPM), and clamps to ≤26.0 V at rated current - used in automotive power supply input stages and industrial motor drive DC bus protection.

For engineers reviewing the 5KP16A-E3/54 datasheet, 5KP16A-E3/54 pinout, 5KP16A-E3/54 application, or 5KP16A-E3/54 equivalent, key selection criteria include unidirectional polarity, P600 package thermal performance, clamping voltage margin vs. protected IC V_DS(max), AEC-Q101 qualification status, and 175 °C maximum junction temperature handling under repetitive surge conditions.

Technical Context

This TVS diode operates as a shunt-clamping device triggered by reverse-biased avalanche breakdown above V_BR. Its glass-passivated P600 junction enables low incremental surge resistance (typ. <0.1 Ω) and sub-nanosecond response time, critical for suppressing fast transients from inductive switching or ESD events.

It is rated for non-repetitive 10/1000 μs waveform surges up to 5000 W with 0.01% duty cycle, derated linearly above 25 °C ambient per Fig. 2, and supports 500 A 8.3 ms half-sine forward surge current - enabling crowbar-circuit replacement in 24 V/48 V industrial power supplies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	16.0 V - Maximum continuous reverse operating voltage before leakage exceeds 2.0 μA; sets upper limit for protected circuit DC rail.
V_BR @ I_T = 5 mA	17.8–19.7 V - Breakdown threshold range defining reliable avalanche initiation; ensures consistent clamping onset across production lot.
V_C @ I_PPM	≤26.0 V - Clamped voltage at 192 A peak pulse; must remain below protected MOSFET or controller V_DS(max) with safety margin.
P_PPM	5000 W - Peak pulse power handling (10/1000 μs); determines survivability against lightning-induced surges per IEC 61000-4-5 Level 4.
T_J(max)	+175 °C - Maximum junction temperature; allows operation in under-hood automotive environments without thermal shutdown.
Polarity	Unidirectional - Cathode-band marked; blocks forward conduction until V_F ≈ 3.5 V at 100 A, enabling DC-bus placement without rectification.
Package	P600 - Axial-leaded, UL 94 V-0 molded epoxy case; provides mechanical robustness and thermal path to PCB copper for >8 W steady-state dissipation at T_L = 75 °C.

Pinout & Package

P600 package: axial-leaded, cylindrical epoxy body with cathode band marking; leads are matte tin-plated, solderable per J-STD-002, rated for 275 °C / 10 s solder dip.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Low-side reference node	Connected to system ground or low-voltage rail; carries full surge return current during clamping event.
Cathode	Protected line interface	Connected to line being protected (e.g., 24 V supply input); avalanche breakdown occurs when voltage exceeds V_BR.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - suitable for engine control unit (ECU) power inputs.
5000 W peak pulse power (10/1000 μs)	Withstands IEC 61000-4-5 combination wave surges up to 4 kV open-circuit / 2 kA short-circuit without degradation.
Clamping ratio V_C/V_BR ≈ 1.35	Low overvoltage margin ensures protected ICs experience minimal over-stress during transient suppression - critical for 3.3 V/5 V logic interfaces.
175 °C max junction temperature	Enables mounting on thermally constrained PCB areas near power converters without derating penalties in high-ambient environments.
Unidirectional polarity only	Simplifies layout in DC systems; eliminates need for series blocking diodes required by bidirectional TVS in single-polarity rails.

Applications

Automotive Power Input Protection	Industrial Motor Drive DC Bus
Use Scenario: 24 V battery-fed ECU power entry subjected to load-dump transients (ISO 7637-2 Pulse 5a, up to 60 V/100 ms).

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, 16 V V_WM, 25.0 V V_C @ 24.7 A - 8× lower IPPM than 5KP16A-E3/54.	Targeted at board-level signal line protection (USB, RS-485), not DC power bus surge absorption.	Select SMBJ16A only when surge energy is limited to <100 mJ and PCB space is constrained; insufficient for IEC 61000-4-5 Level 4.
1.5KE16A	Same P600 package, 16 V V_WM, but lower PPPM (1500 W), 100 A IPPM, and higher V_C (25.6 V) - legacy series with reduced surge margin.	Legacy industrial equipment where footprint compatibility is mandatory but surge test compliance has been downgraded.	Choose 1.5KE16A only for cost-sensitive replacements in non-certified designs; lacks AEC-Q101 qualification and fails IEC 61000-4-5 Level 4 margin.

Compared with SMBJ16A and 1.5KE16A, the 5KP16A-E3/54 delivers 3.3× higher peak power and AEC-Q101 validation - making it the sole option among the three qualified for automotive power rail protection requiring sustained 5 kV surge immunity.

FAQ

What is the maximum clamping voltage of the 5KP16A-E3/54 during a 10/1000 μs surge?

The 5KP16A-E3/54 clamps to a maximum of 26.0 V when subjected to its rated peak pulse current of 192 A (10/1000 μs waveform). This value is guaranteed across temperature and process variation per Vishay Document 88308, ensuring protected circuitry remains within safe overvoltage limits during surge events.

Is the 5KP16A-E3/54 suitable for automotive applications?

Yes, the 5KP16A-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, robust P600 package, and validated surge endurance make it appropriate for ECU power input protection and body control module applications per ISO 7637-2 and ISO 16750-2 standards.

Does the 5KP16A-E3/54 have bidirectional polarity?

No, the 5KP16A-E3/54 is unidirectional only, with a cathode band marking the protected line terminal. It conducts in reverse avalanche mode above V_BR but blocks forward current up to 3.5 V at 100 A - making it ideal for DC power rail protection where polarity is fixed and negative transients are not expected.

What is the thermal derating behavior of the 5KP16A-E3/54 above 25 °C ambient?

The 5KP16A-E3/54 follows linear thermal derating per Figure 2 in Vishay Document 88308: peak pulse power decreases by approximately 0.5% per °C above 25 °C ambient. At 100 °C, its PPPM drops to ~3750 W, and at 150 °C, it falls to ~2500 W - requiring layout attention to heatsinking in high-temperature enclosures.

How does the 5KP16A-E3/54 compare to standard Zener diodes for surge protection?

Unlike standard Zener diodes, the 5KP16A-E3/54 is optimized for high-energy transient suppression: it offers 5000 W peak pulse power, low incremental resistance (<0.1 Ω), and sub-nanosecond response - whereas Zeners typically handle <5 W pulses and exhibit higher dynamic impedance, leading to excessive clamping voltage overshoot during fast surges.
