Product details
Overview
P6KA13AHE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection of sensitive electronics. It features a 12.4 V to 13.7 V breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), and AEC-Q101 qualification - deployed in automotive power line and sensor interface protection.
For engineers reviewing the P6KA13AHE3/54 datasheet, P6KA13AHE3/54 pinout, P6KA13AHE3/54 application, or P6KA13AHE3/54 equivalent, key selection criteria include clamping voltage at rated surge current (18.2 V), junction temperature capability up to +185 °C, unidirectional polarity, DO-204AC (DO-15) package compatibility, and low leakage (<2.0 μA at VWM).
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable high-temperature operation. Its 185 °C maximum junction temperature and AEC-Q101 qualification confirm suitability for under-hood automotive environments and industrial control systems requiring long-term reliability.
The device delivers 33.0 A peak pulse current (IPPM) at 10/1000 μs waveform with a clamping voltage of 18.2 V, enabling effective suppression of inductive switching transients and ESD events. Its low incremental surge resistance and fast response time ensure minimal voltage overshoot during transient events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V - defines reliable conduction onset range under 1.0 mA test current; ensures consistent turn-on across production lots and temperature. |
| VWM | 11.1 V - maximum continuous reverse operating voltage before significant leakage; sets safe DC bias margin for 12 V automotive systems. |
| VC @ IPPM | 18.2 V - clamped voltage at 33.0 A surge; limits downstream IC stress below 20 V during 10/1000 μs transients. |
| IPPM | 33.0 A - peak surge current handling capacity; supports protection against ISO 7637-2 Pulse 1/2a/5a waveforms in vehicle ECUs. |
| TJ max. | +185 °C - enables operation in high-ambient under-hood locations without derating; validated per AEC-Q101 stress tests. |
| Polarity | Unidirectional - provides reverse-biased clamping only; requires correct orientation relative to protected line polarity. |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 9.5 mm body length; compatible with legacy through-hole assembly and reflow soldering (275 °C, 10 s). |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode indicated by color band. Matte tin-plated leads meet J-STD-002 solderability and JESD 22-B102 thermal shock requirements. HE3 suffix denotes RoHS-compliant, AEC-Q101 qualified construction with JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during forward surge events (e.g., reverse battery connection). |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail); initiates avalanche breakdown when line voltage exceeds VBR, shunting surge current to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier process ensures stable VBR and low leakage over 15+ year automotive life at 150 °C junction temperature. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TCT, UHAST, and ESD (HBM ≥ 8 kV), enabling use in safety-critical ECU power rails. |
| 600 W peak pulse power | Rated at 10/1000 μs waveform with 0.01 % duty cycle; sustains repeated load-dump surges without parametric shift or failure. |
| Low clamping ratio (VC/VBR) | 1.47 (18.2 V / 12.4 V min) - minimizes voltage overshoot during transients, reducing stress on downstream MOSFETs and CAN transceivers. |
| High-temperature operation | Full functionality maintained from -65 °C to +185 °C; eliminates need for external thermal derating in engine-control modules. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|

Use Value: Maintains signal integrity with <2.0 μA leakage at 11.1 V, avoiding offset errors in 4–20 mA current-loop interfaces. |
| Telecom Line Card Surge Suppression | Consumer Appliance Motor Drive Protection |
|
Use Scenario: Shielding Ethernet PHY power pins and RS-485 transceiver VCC rails from lightning-induced surges in outdoor telecom cabinets. IC Role / Device Role: Primary clamping device on 3.3 V/5 V auxiliary rails, coordinated with GDT or MOV secondary protection. Use Value: Fast 1 ns response time limits transient energy delivery, preserving PHY ICs during 10/1000 μs common-mode surges. |
Use Scenario: Protecting gate drivers and MCU I/O in washing machine motor control boards exposed to relay coil flyback and brush arcing. IC Role / Device Role: TVS mounted across relay coil terminals and across MCU GPIO lines connected to hall-effect sensors. Use Value: Withstands 75 A non-repetitive surge (8.3 ms half-sine), preventing reset or brownout during repeated motor start-stop cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A | Lower peak pulse power (400 W), higher VC (20.9 V at 24.4 A), same DO-214AC package - not AEC-Q101 qualified. | Targeted at commercial-grade consumer electronics; lacks automotive temperature and reliability validation. | Select SMAJ12A only for cost-sensitive non-automotive designs where 185 °C operation and AEC-Q101 compliance are unnecessary. |
| 1.5KE12A | Higher VBR tolerance (11.4–12.6 V), larger DO-204AL (DO-41) package, 1500 W rating but higher VC (19.9 V at 75.5 A). | Used in high-energy industrial AC line protection; less suitable for space-constrained PCBs due to longer body (9.5 mm vs. 7.6 mm axial length). | Choose 1.5KE12A when surge energy exceeds 600 W capability and board layout accommodates larger axial package. |
Compared with SMAJ12A and 1.5KE12A, the P6KA13AHE3/54 uniquely combines AEC-Q101 qualification, +185 °C operation, and DO-204AC footprint - making it the only option among the three qualified for under-hood automotive deployment without layout or thermal redesign.

FAQ
What is the breakdown voltage range of the P6KA13AHE3/54?
The P6KA13AHE3/54 has a specified breakdown voltage (VBR) range of 12.4 V to 13.7 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures predictable clamping behavior across temperature and production batches, critical for protecting 12 V automotive systems where overvoltage margins are narrow.
Is the P6KA13AHE3/54 suitable for automotive applications?
Yes, the P6KA13AHE3/54 is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature, making it fully compliant for under-hood automotive use. Its construction meets JESD 201 Class 2 whisker resistance and solderability standards, and it is validated for load dump, ESD, and thermal cycling per automotive reliability protocols.
What does the "HE3/54" suffix indicate in P6KA13AHE3/54?
The "HE3" suffix denotes RoHS-compliant, matte tin-plated leads meeting J-STD-002 and JESD 22-B102, plus JESD 201 Class 2 whisker resistance. The "/54" indicates packaging in 13-inch paper tape and reel with 4000 units per reel - standard for automated SMT placement despite its axial DO-204AC form factor.
How does the clamping voltage of P6KA13AHE3/54 compare to its breakdown voltage?
The P6KA13AHE3/54 clamps at 18.2 V when subjected to its rated 33.0 A peak pulse current (10/1000 μs), yielding a clamping ratio (VC/VBR(min)) of 1.47. This low ratio ensures minimal overvoltage exposure to protected ICs, especially important for modern 3.3 V or 5 V logic interfacing with 12 V power domains.
Can P6KA13AHE3/54 be used in bidirectional protection circuits?
No, the P6KA13AHE3/54 is unidirectional only, with clamping action occurring only in reverse bias. For bidirectional transient suppression (e.g., data lines subject to ± surges), a dedicated bidirectional TVS such as SMBJ12CA or a back-to-back diode configuration would be required - the P6KA13AHE3/54 must be oriented with cathode toward the protected line.
