Product details

Overview

5KP160A-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection of power rails and signal lines. It features 160 V stand-off voltage (VWM), 178–197 V breakdown voltage (VBR), 5000 W peak pulse power (10/1000 μs), 19.3 A peak pulse current (IPPM), and clamps to ≤259 V at rated surge. It is AEC-Q101 qualified and used in automotive power supply output protection.

For engineers reviewing the 5KP160A-E3/54 datasheet, 5KP160A-E3/54 pinout, 5KP160A-E3/54 application, or 5KP160A-E3/54 equivalent, key selection criteria include unidirectional polarity, P600 package thermal handling, clamping voltage vs. protected IC V_DS(max), I_PPM derating above 25 °C, and compliance with AEC-Q101 for automotive under-hood use.

Technical Context

The 5KP160A-E3/54 employs a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional structure provides robust forward conduction during overvoltage events while maintaining tight V_BR tolerance (±5.3%) and low leakage (<2.0 μA at 160 V).

Designed for crowbar-replacement operation in switching power supplies, it sustains 500 A non-repetitive forward surge (8.3 ms half-sine) and operates from –55 °C to +175 °C junction temperature. Thermal derating begins above 25 °C ambient, with full 8.0 W power dissipation only at lead temperature ≤75 °C on infinite heatsink.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	160 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC rail margin for protected circuit.
V_BR @ I_T = 5 mA	178–197 V - Breakdown voltage range at 5 mA test current; ensures reliable turn-on before downstream component overvoltage.
I_PPM (10/1000 μs)	19.3 A - Peak surge current capability; determines minimum trace width and fuse coordination for 5 kA-level transients.
V_C @ I_PPM	≤259 V - Clamped voltage at rated surge; must be below absolute maximum rating of protected MOSFET or IC.
P_PPM	5000 W - Peak pulse power rating; enables single-event suppression of lightning-induced surges per IEC 61000-4-5 Level 4.
T_J max.	+175 °C - Maximum junction temperature; supports under-hood automotive placement with minimal heatsinking.
Polarity	Unidirectional - Cathode marked by band; allows forward conduction during positive transients, not bidirectional AC line protection.

Pinout & Package

Package: P600 molded epoxy case with matte tin-plated leads; meets UL 94 V-0 flammability; RoHS compliant (E3 suffix); cathode indicated by color band.

Pin/Terminal	Circuit Role	Design Meaning

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 SMAJ160A	Same V_WM (160 V), lower P_PPM (400 W), DO-214AC package, 12.5 A I_PPM, 259 V V_C.	Lower surge capacity suits consumer-grade 12 V systems; unsuitable for automotive load dump or industrial 4 kV testing.	Select when board space is constrained and surge energy is limited to <100 mJ; verify thermal design for repeated events.
ON Semiconductor 1.5KE160A	Same V_WM (160 V), same P_PPM (5000 W), DO-201AD package, 19.3 A I_PPM, 259 V V_C, but not AEC-Q101 qualified.	Lacks automotive qualification; suitable for industrial/commercial power supplies where AEC-Q101 is not mandated.	Choose for cost-sensitive industrial designs requiring identical electrical specs but no automotive reliability validation.

Compared with 5KP160A-E3/54, SMAJ160A offers smaller footprint but sacrifices >90% surge energy handling, while 1.5KE160A matches power rating but omits AEC-Q101 validation-making 5KP160A-E3/54 the only option qualified for under-hood automotive deployment with full 5 kW capability.

FAQ

What is the clamping voltage of the 5KP160A-E3/54 under full-rated surge conditions?

The 5KP160A-E3/54 clamps to a maximum of 259 V when subjected to its rated 19.3 A peak pulse current (10/1000 μs waveform). This value is measured per JEDEC standards and guarantees that protected circuitry sees no more than 259 V during a 5000 W transient event. The clamping voltage remains stable across temperature and lifetime if operated within datasheet limits.

Is the 5KP160A-E3/54 suitable for bidirectional AC line protection?

No, the 5KP160A-E3/54 is unidirectional only, with polarity marked by a cathode band. It conducts in forward bias during positive transients but blocks reverse voltage beyond V_WM. For AC line protection requiring symmetrical clamping, a bidirectional variant such as 5KP160CA must be selected instead-5KP160A-E3/54 is intended for DC rail or single-polarity signal line protection.

Does the 5KP160A-E3/54 require a heatsink for continuous power dissipation?

The 5KP160A-E3/54 is rated for 8.0 W power dissipation only when mounted on an infinite heatsink at lead temperature ≤75 °C. In typical PCB applications without dedicated heatsinking, steady-state dissipation is limited to ~1.5 W due to thermal resistance. It is designed for transient (not continuous) power handling; sustained DC power must be managed via layout and thermal vias-not heatsinks.

How does AEC-Q101 qualification impact the use of 5KP160A-E3/54 in automotive designs?

AEC-Q101 qualification confirms that the 5KP160A-E3/54 has passed accelerated stress tests-including temperature cycling, humidity bias, and high-temperature operating life-for use in automotive electronic modules. This allows direct placement in engine control units, body controllers, and ADAS power supplies without additional qualification, reducing time-to-market and validation risk for Tier 1 suppliers.

Can the 5KP160A-E3/54 replace a 5KP150A in an existing design?

Substituting 5KP160A-E3/54 for 5KP150A increases V_WM from 150 V to 160 V and V_BR from 167–185 V to 178–197 V, raising clamping threshold. This may reduce protection margin if the protected circuit's absolute maximum rating is close to 160 V. Verify that all transient threats remain below the new 259 V clamping level and that system fault detection timing accommodates the higher turn-on voltage.
