Product details
Overview
5KP20AHE3_A/C from Vishay General Semiconductor is a unidirectional 5000 W transient voltage suppressor (TVS) diode in P600 package, featuring 20 V stand-off voltage (VWM), 22.2–24.5 V breakdown voltage (VBR) at 5 mA, and 154 A peak pulse current (IPPM) with 10/1000 μs waveform - designed for automotive-grade overvoltage protection of power rails and signal lines in switching power supplies and motor control circuits.
For engineers reviewing the 5KP20AHE3_A/C datasheet, 5KP20AHE3_A/C pinout, 5KP20AHE3_A/C application, or 5KP20AHE3_A/C equivalent, this AEC-Q101 qualified TVS offers verified clamping performance (VC = 32.4 V at IPPM), low incremental surge resistance, and robust thermal derating up to 175 °C junction temperature - critical for high-reliability industrial and automotive designs.
Technical Context
The 5KP20AHE3_A/C employs a glass-passivated P600 chip junction optimized for high-energy transient suppression using a 10/1000 μs waveform. Its unidirectional polarity enables precise reverse-biased clamping on DC power rails without forward conduction during normal operation.
It delivers 5000 W peak pulse power with 0.01 % duty cycle, supports 500 A non-repetitive forward surge current (IFSM), and maintains stable clamping up to TJ = 175 °C - validated per AEC-Q101 stress tests including temperature cycling, HTRB, and ESD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 20 V - maximum continuous reverse operating voltage before clamping initiates; defines safe DC rail margin for 24 V systems. |
| VBR min/max | 22.2 V / 24.5 V at IT = 5 mA - tight breakdown tolerance ensures predictable turn-on across production lots. |
| VC @ IPPM | 32.4 V at 154 A - clamping voltage limits downstream IC stress during lightning or inductive-switching transients. |
| PPPM | 5000 W - peak pulse power handling with 10/1000 μs waveform enables protection against IEC 61000-4-5 Level 4 surges. |
| TJ max | +175 °C - extended junction temperature rating supports under-hood automotive and high-ambient industrial use. |
| Polarity | Unidirectional - suitable for DC power line protection where reverse conduction must be blocked during normal operation. |
| Package | P600 - industry-standard axial-leaded package with UL 94 V-0 epoxy body and matte tin-plated leads. |
Pinout & Package
P600 package: axial-leaded, molded epoxy body with cathode band marking; lead length 9.1–9.5 mm, body diameter 9.1–9.5 mm, overall length ≥25.4 mm; RoHS-compliant, AEC-Q101 qualified (HE3 suffix), JESD 22-B106 solderable (275 °C, 10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / clamping reference | Connected to lower-potential side (e.g., ground or return path); defines direction of transient energy shunting. |
| Cathode | Clamping output / protected node connection | Connected to protected line (e.g., +24 V rail); conducts when transient exceeds VWM, clamping voltage to ≤32.4 V. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including temperature cycling, HTRB, and ESD robustness - no additional qualification required for Tier 1 programs. |
| 5000 W peak pulse power | Withstands IEC 61000-4-5 4 kV surge (10/1000 μs) without degradation, enabling single-device protection for 24 V power inputs. |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage stress on downstream MOSFETs and controllers during transients - critical for gate driver and MCU supply protection. |
| 175 °C max junction temperature | Supports operation in engine bay or enclosed industrial enclosures without thermal derating penalties beyond datasheet curves. |
| Matte tin-plated leads | Ensures reliable solderability per J-STD-002 and JESD 22-B102, with JESD 201 Class 2 whisker resistance for long-term reliability. |
Applications
| Automotive Power Rail Protection | Industrial Switching Power Supply Output |
|---|---|
|

IC Role / Device Role / Timing Role: Precision clamping element after coarse surge suppression, limiting residual transients to <33 V. Use Value: Tight VBR tolerance (±5 %) ensures consistent coordination with upstream protectors and avoids premature triggering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ20A | Lower PPPM (600 W), SMC package, same VWM (20 V), higher VC (32.4 V vs. 34.0 V), non-AEC-Q101 | Best suited for cost-sensitive consumer or non-automotive industrial PCBs with space constraints | Select SMBJ20A only if peak surge energy is ≤600 W and AEC-Q101 is not required. |
| 1.5KE20A | Same P600 package, lower PPPM (1500 W), same VWM (20 V), higher VC (36.0 V), commercial grade only | Appropriate for legacy designs or low-energy transients where 5000 W headroom is unnecessary | Choose 1.5KE20A only when system-level surge testing confirms ≤1500 W requirements and automotive qualification is waived. |
Compared with SMBJ20A and 1.5KE20A, the 5KP20AHE3_A/C provides 3.3× and 3.3× higher peak pulse power respectively, full AEC-Q101 validation, and tighter VBR tolerance - making it the sole choice for automotive power modules and high-reliability industrial SMPS outputs requiring sustained 5 kW surge handling.

FAQ
What is the clamping voltage of the 5KP20AHE3_A/C at its rated peak pulse current?
The 5KP20AHE3_A/C has a maximum clamping voltage (VC) of 32.4 V when subjected to its rated peak pulse current (IPPM) of 154 A using a 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that protected circuitry sees no more than 32.4 V during worst-case transient events - a critical parameter for ensuring compatibility with 36 V-rated downstream components in automotive and industrial systems. The 5KP20AHE3_A/C maintains this clamping performance across its full operating temperature range.
Is the 5KP20AHE3_A/C qualified for automotive applications?
Yes, the 5KP20AHE3_A/C is explicitly AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3". This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and electrostatic discharge - validating its suitability for under-hood and chassis-mounted automotive electronics. The 5KP20AHE3_A/C meets the reliability requirements for powertrain, body control, and ADAS modules where transient immunity is mission-critical.
What does the "_A/C" suffix mean in 5KP20AHE3_A/C?
The "_A/C" suffix in 5KP20AHE3_A/C indicates the preferred packaging configuration: "C" denotes 13-inch diameter paper tape and reel with a base quantity of 800 units, while "A" refers to the revision level of the manufacturing process or test specification. This ordering code aligns with Vishay's standard P600 packaging nomenclature and ensures traceability to AEC-Q101 qualified production lots. The 5KP20AHE3_A/C is RoHS compliant and meets JESD 201 Class 2 whisker resistance requirements.
How does the 5KP20AHE3_A/C compare to standard 1.5KE series TVS diodes?
The 5KP20AHE3_A/C delivers 3.3× higher peak pulse power (5000 W vs. 1500 W for 1.5KE20A), lower clamping ratio (VC/VBR ≈ 1.4 vs. ~1.5), and AEC-Q101 qualification - whereas 1.5KE20A is commercial-grade only. Both share the P600 package, but the 5KP20AHE3_A/C sustains higher surge currents (154 A vs. 69 A) and operates reliably up to 175 °C junction temperature. For new automotive or high-end industrial designs, the 5KP20AHE3_A/C replaces 1.5KE20A where enhanced surge margin and qualification are mandatory.
Can the 5KP20AHE3_A/C be used in bidirectional configurations?
No, the 5KP20AHE3_A/C is unidirectional only, as specified in Vishay's datasheet and indicated by the cathode band marking. It conducts and clamps only in reverse bias - making it unsuitable for AC line protection or bidirectional signal line applications. For bidirectional transient suppression, engineers must select a dedicated bidirectional variant such as 5KP20CA, or use back-to-back unidirectional devices. The 5KP20AHE3_A/C's design intent is strictly DC power rail protection where polarity is fixed and reverse conduction must be blocked during normal operation.
