Product details
Overview
P6KA11AHE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection of sensitive electronics. It features a 10.5 V to 11.6 V breakdown voltage (VBR), 9.40 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), 38.5 A peak pulse current (IPPM), and 15.6 V clamping voltage (VC) - deployed in automotive power line and sensor interface protection.
For engineers reviewing the P6KA11AHE3/54 datasheet, P6KA11AHE3/54 pinout, P6KA11AHE3/54 application, or P6KA11AHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction rating, DO-204AC (DO-15) package, unidirectional polarity, and low 5.0 μA reverse leakage at VWM under TJ = 150 °C conditions.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with optimized junction passivation for high reliability under thermal stress. Its 185 °C maximum junction temperature and AEC-Q101 qualification confirm suitability for under-hood automotive environments where sustained high-temperature operation is required.
The device delivers precise clamping performance with a 15.6 V max clamping voltage at 38.5 A IPPM, low incremental surge resistance, and fast response time - enabling effective suppression of inductive switching transients and ESD events on 12 V power rails and signal lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 10.5 V / 11.6 V - ensures reliable triggering above normal 12 V system operating voltage while avoiding false trips. |
| VWM | 9.40 V - maximum continuous reverse working voltage compatible with 12 V nominal automotive systems. |
| IPPM | 38.5 A - peak surge current handling capability under standardized 10/1000 μs waveform for transient immunity validation. |
| VC | 15.6 V - clamped voltage during full-rated surge, protecting downstream ICs rated for ≤16 V absolute maximum. |
| TJ max. | +185 °C - enables operation in high-ambient under-hood locations without derating concerns up to specified limits. |
| Leakage (TJ = 150 °C) | 5.0 μA - ultra-low reverse leakage preserves power integrity in always-on vehicle modules. |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with matte tin-plated leads compliant to J-STD-002. |
Pinout & Package
DO-204AC (DO-15) molded epoxy package with axial leads; cathode denoted by color band. Leads are matte tin plated, solderable per J-STD-002 and JESD 22-B102, qualified to JESD 201 Class 2 whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional TVS configuration. |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail or signal); color band identifies this end for correct PCB orientation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per stress test requirements. |
| 185 °C junction rating | Supports uninterrupted operation in engine control units (ECUs), body controllers, and ADAS sensors exposed to under-hood heat. |
| 600 W peak pulse power (10/1000 μs) | Meets ISO 7637-2 Pulse 1, 2a, and 5a immunity requirements for 12 V vehicle networks. |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes let-through energy during transients, reducing stress on downstream MOSFETs and microcontrollers. |
| Uni-directional polarity only | Simplifies layout and eliminates risk of reverse-bias failure in DC-coupled protection paths like power supply inputs. |
Applications
| Automotive Power Line Protection | Engine Control Unit (ECU) Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | Same VWM (9.4 V), slightly higher VC (18.2 V), lower IPPM (32.3 A), SMA package (surface-mount). | Not AEC-Q101 qualified; intended for commercial/industrial use only. | Select when board space constraints favor SMD and automotive qualification is not required. |
| 1.5KE11A | Higher power (1500 W), larger DO-201 package, same VBR range but higher VC (18.2 V), non-AEC-Q101. | Designed for general-purpose industrial surge suppression, not optimized for automotive thermal cycling. | Choose for higher-energy transients where footprint and qualification are secondary to peak power handling. |
Compared with SMAJ11A and 1.5KE11A, P6KA11AHE3/54 offers AEC-Q101 qualification, superior thermal robustness (185 °C), tighter VC (15.6 V), and DO-204AC form factor optimized for through-hole automotive harness interfaces - making it the preferred choice for production automotive ECUs and BCMs.

FAQ
What is the maximum clamping voltage of the P6KA11AHE3/54 under full-rated surge conditions?
The P6KA11AHE3/54 has a maximum clamping voltage (VC) of 15.6 V when subjected to its rated peak pulse current of 38.5 A using the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components with 16 V absolute maximum ratings remain within safe operating limits during transient events.
Is the P6KA11AHE3/54 qualified for automotive applications?
Yes, the P6KA11AHE3/54 is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature. Its construction - including passivated anisotropic rectifier technology, matte tin-plated leads, and UL 94 V-0 molding compound - meets automotive reliability requirements for under-hood and chassis-mounted modules.
What does the "HE3/54" suffix indicate in P6KA11AHE3/54?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified packaging with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 2 whisker resistance. The "/54" indicates tape-and-reel packaging in 13-inch diameter reels containing 4000 units, per Vishay's ordering nomenclature.
How does the P6KA11AHE3/54 differ from the non-"A" variant P6KA11?
The P6KA11AHE3/54 has a tighter breakdown voltage range (10.5 V to 11.6 V) versus P6KA11 (9.90 V to 12.1 V), resulting in more consistent clamping behavior and reduced unit-to-unit variation. Both share identical package, power rating, and AEC-Q101 qualification, but P6KA11AHE3/54 is preferred for designs requiring tighter VBR tolerance.
Can the P6KA11AHE3/54 be used in bidirectional configurations?
No, the P6KA11AHE3/54 is unidirectional only, as explicitly stated in the datasheet. It must be oriented with cathode toward the protected line. For bidirectional protection, two P6KA11AHE3/54 devices may be connected in series opposing, but Vishay does not characterize or guarantee performance in that configuration - dedicated bidirectional TVS devices should be used instead.
