Product details
Overview
5KP70AHE3_A/C from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection in power supply outputs and automotive electronics. It features 70 V stand-off voltage (VWM), 77.8–86.0 V breakdown voltage (VBR), 5000 W peak pulse power (10/1000 μs), 44.2 A peak pulse current (IPPM), and clamps to ≤113 V at rated current - enabling robust protection of MOSFETs and ICs against lightning-induced transients and inductive switching spikes.
For engineers reviewing the 5KP70AHE3_A/C datasheet, 5KP70AHE3_A/C pinout, 5KP70AHE3_A/C application, or 5KP70AHE3_A/C equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, unidirectional polarity with cathode band marking, and compatibility with 13" tape-and-reel delivery for automated assembly in industrial and automotive production environments.
Technical Context
The 5KP70AHE3_A/C employs a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional structure provides precise reverse-biased clamping without forward conduction during normal operation, making it suitable for DC bus protection where polarity is fixed.
It is rated for 5000 W peak pulse power under JEDEC-standard 10/1000 μs waveform at 0.01% duty cycle, with thermal derating above 25 °C per Fig. 2 and power dissipation limited to 8.0 W on infinite heatsink at TL = 75 °C. The device meets JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 70 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC RMS working range. |
| VBR (min/max) | 77.8 V / 86.0 V at 5 mA - guaranteed breakdown threshold ensures reliable turn-on during overvoltage events. |
| VC @ IPPM | ≤113 V at 44.2 A - clamping voltage limits stress on downstream components during 10/1000 μs surge. |
| PPPM | 5000 W - peak pulse power handling capacity determines survivability against lightning or load-switching transients. |
| TJ max. | +175 °C - high junction temperature rating supports operation in under-hood automotive and industrial power systems. |
| Polarity | Unidirectional - requires correct orientation in circuit; cathode marked by color band for PCB layout verification. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; RoHS-compliant, UL 94 V-0 rated; 0.375" (9.5 mm) body length; lead pitch not specified in source but standardized for axial-leaded P600 format.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during clamping | Connected to lower-potential side (e.g., ground or return path); must be routed with low-inductance trace. |
| Cathode | Reverse-biased clamping node | Marked by color band; connected to protected line (e.g., +12 V rail); defines directionality of surge suppression. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables single-device protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 12 V/24 V systems. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain and body electronics without additional qualification effort. |
| Low clamping ratio (VC/VBR ≈ 1.31) | Minimizes overvoltage overshoot during transient events, reducing risk of MOSFET gate oxide failure. |
| P600 glass-passivated junction | Provides stable electrical characteristics over lifetime and resistance to humidity/moisture ingress. |
| Junction temperature range: –55 °C to +175 °C | Supports deployment in engine control units, battery management systems, and industrial motor drives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ70A-E3/52 (Vishay) | Lower PPPM (600 W), smaller SMB package, same VWM/VBR range | Not rated for AEC-Q101; limited to consumer/industrial use below 100 A surge demand | Select when board space is constrained and surge energy is ≤600 W; verify thermal relief for repeated events. |
| 1.5KE70A (ON Semiconductor) | Same VWM (70 V), lower PPPM (1500 W), DO-201 package, non-AEC-Q101 | Lacks automotive qualification and thermal robustness for under-hood deployment | Acceptable for cost-sensitive commercial power supplies where 5000 W capability is unnecessary. |
Compared with SMBJ70A-E3/52 and 1.5KE70A, the 5KP70AHE3_A/C delivers 3.3× and 3.3× higher peak pulse power respectively, maintains AEC-Q101 compliance, and supports higher sustained surge repetition rates due to superior thermal mass in P600 packaging - critical for automotive and heavy industrial applications.

FAQ
What is the clamping voltage of the 5KP70AHE3_A/C at its rated peak pulse current?
The 5KP70AHE3_A/C clamps to a maximum of 113 V when subjected to its rated peak pulse current of 44.2 A under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and guarantees upper-bound voltage stress on protected circuitry during surge events. The clamping performance is consistent across the full operating temperature range and forms the basis for downstream component voltage rating selection in designs using the 5KP70AHE3_A/C.
Is the 5KP70AHE3_A/C suitable for automotive applications?
Yes, the 5KP70AHE3_A/C is AEC-Q101 qualified, confirming its reliability for automotive use cases including engine control units, body electronics, and battery management systems. Its –55 °C to +175 °C operating junction temperature range, robust P600 package, and validated performance under temperature cycling and humidity testing make it appropriate for under-hood and chassis-mounted deployments where the 5KP70AHE3_A/C is expected to operate continuously under thermal and mechanical stress.
How does the 5KP70AHE3_A/C differ from the 5KP70A-E3/54 variant?
The 5KP70AHE3_A/C differs from 5KP70A-E3/54 in qualification level and packaging: the "HE3" suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, while "E3" alone indicates commercial-grade RoHS compliance only. The "_A/C" suffix specifies C-packaging - 13" paper tape and reel with 800-unit base quantity - whereas "/54" denotes a different reel configuration. Both share identical electrical specs, but only the 5KP70AHE3_A/C is approved for automotive production use.
What is the maximum reverse leakage current of the 5KP70AHE3_A/C at its stand-off voltage?
At its 70 V stand-off voltage (VWM), the 5KP70AHE3_A/C exhibits a maximum reverse leakage current (ID) of 2.0 μA at 25 °C. This low leakage ensures minimal standby power loss in always-on automotive modules and prevents false triggering in high-impedance sensing circuits. Leakage remains within specification up to TJ = 125 °C, with gradual increase governed by semiconductor physics - verified in Vishay's characterization data for the 5KP70AHE3_A/C family.
Can the 5KP70AHE3_A/C be used in bidirectional configurations?
No, the 5KP70AHE3_A/C is unidirectional only, as explicitly stated in the Vishay datasheet. It conducts and clamps only in reverse bias; forward conduction occurs above ~3.5 V but is not designed for symmetrical surge suppression. For bidirectional protection, two 5KP70AHE3_A/C devices must be connected in series opposition, or a dedicated bidirectional TVS such as 5KP70CA should be selected - the 5KP70AHE3_A/C itself does not support AC or dual-polarity transient suppression without external circuitry.
