Product details
Overview
P6KA30AHE3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 30 V standoff voltage (VWM = 25.6 V), 31.5 V minimum breakdown voltage (VBR), 600 W peak pulse power (10/1000 μs), 14.5 A peak pulse current (IPPM), and clamps to 41.4 V at rated surge - deployed in automotive power supplies, industrial sensor interfaces, and MOSFET gate protection circuits.
For engineers reviewing the P6KA30AHE3/73 datasheet, P6KA30AHE3/73 pinout, P6KA30AHE3/73 application, or P6KA30AHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction rating, DO-204AC (DO-15) package compatibility, and verified clamping performance under repetitive 0.01% duty cycle transients.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable high-temperature operation up to TJ = 185 °C. Its unidirectional polarity enables integration into DC-biased lines where reverse conduction must be blocked during normal operation.
The device delivers precise clamping with low incremental surge resistance and fast response time, validated per ANSI/IEEE C62.35 standards using 10/1000 μs waveform testing. It is rated for 75 A non-repetitive forward surge (8.3 ms half-sine) and exhibits a +0.097 %/°C temperature coefficient of VBR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 25.6 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 28.5–31.5 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering above normal operating voltage. |
| VC (Clamping Voltage) | 41.4 V at IPPM = 14.5 A - Peak voltage seen by protected circuit during 10/1000 μs surge; critical for downstream IC survival. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized transient waveform; validates robustness against IEC 61000-4-5 surges. |
| TJ max. | 185 °C - Enables use in under-hood automotive and high-ambient industrial environments without derating penalties. |
| Polarity | Unidirectional - Blocks reverse current during normal operation; suited for DC supply rail and biased signal line protection. |
| AEC-Q101 Qualified | Yes - Certified for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per JESD47. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case with UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards; cathode denoted by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / surge return path | Connected to ground or low-impedance return in unidirectional configuration; completes clamping loop during transient. |
| Cathode | Protected line connection / surge input | Connected to line being protected (e.g., 24 V rail or sensor output); avalanche conduction initiates here during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation optimized design | Enables stable leakage and breakdown behavior across -65 °C to +185 °C; eliminates parametric drift in harsh thermal cycles. |
| 600 W peak pulse power (10/1000 μs) | Validated surge handling for ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 3/4 transients in automotive ECUs. |
| AEC-Q101 qualification | Confirms compliance with automotive stress tests including HTGB, H3TRB, and mechanical shock - required for Tier-1 production. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns rise time), improving protection margin for sensitive gate drivers. |
| HE3 suffix | Meets JESD 201 Class 2 whisker resistance; eliminates tin whisker risk in long-life sealed modules and high-reliability systems. |
Applications
| Automotive Power Supply Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 24 V battery-fed control modules from load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges above 32 V. Use Value: Limits voltage to ≤41.4 V during 14.5 A transients, preventing damage to MCU power inputs and CAN transceivers. | Use Scenario: Safeguarding analog outputs of pressure/temperature sensors connected to PLC analog inputs. IC Role / Device Role / Timing Role: TVS mounted at sensor connector to shunt induced lightning or EFT noise on 4–20 mA or 0–10 V lines. Use Value: Clamps fast transients within nanoseconds while maintaining <1 μA leakage at 25.6 V, preserving measurement accuracy. |
| MOSFET Gate Driver Protection | Telecom DC Power Interface |
Use Scenario: Shielding high-side N-channel MOSFET gates driven by isolated PWM controllers in motor drives. IC Role / Device Role / Timing Role: TVS placed between gate and source to suppress Miller-induced voltage spikes during switching transitions. Use Value: Responds in <1 ns to limit gate-source voltage to safe levels (<±20 V), avoiding unintended turn-on or oxide rupture. | Use Scenario: Front-end surge suppression on -48 V telecom power feeds entering base station equipment. IC Role / Device Role / Timing Role: Unidirectional TVS installed on negative rail to absorb positive-going surges relative to return. Use Value: Handles repeated 600 W pulses with 0.01% duty cycle, supporting GR-1089-CORE Level 3 compliance without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | Same DO-214AC (SMA) package; lower PPPM (400 W); VBR min = 33.3 V; no AEC-Q101 qualification. | Not qualified for automotive under-hood use; suitable only for commercial-grade consumer or industrial PCBs with lower surge severity. | Select SMAJ30A only when AEC-Q101 is not required and board space allows SMA footprint instead of DO-15. |
| 1.5KE30A | DO-201AD package; higher PPPM (1500 W); VBR min = 31.8 V; same unidirectional polarity; AEC-Q101 not claimed. | Larger footprint and higher clamping (47.3 V at 31.8 A); better for high-energy surges but less precise voltage margin near 30 V rails. | Choose 1.5KE30A when system-level surge energy exceeds 600 W and layout accommodates larger axial package. |
Compared with SMAJ30A and 1.5KE30A, P6KA30AHE3/73 uniquely combines AEC-Q101 qualification, DO-15 form factor, and tight 28.5–31.5 V VBR range - making it optimal for space-constrained automotive modules requiring certified reliability and precise clamping near 24 V systems.

FAQ
What is the maximum clamping voltage of the P6KA30AHE3/73 under rated surge conditions?
The P6KA30AHE3/73 clamps to a maximum of 41.4 V when subjected to its rated peak pulse current of 14.5 A using the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the worst-case voltage imposed on the protected circuit during surge events, ensuring compatibility with 3.3 V, 5 V, and 24 V logic and power stages.
Is the P6KA30AHE3/73 suitable for automotive applications?
Yes, the P6KA30AHE3/73 is AEC-Q101 qualified and rated for operation up to TJ = 185 °C, making it suitable for under-hood and powertrain applications. Its DO-204AC package, HE3 whisker-resistant plating, and validated surge performance per ISO 7637-2 meet Tier-1 automotive requirements - confirmed in Vishay document 88368.
What does the "HE3" suffix indicate in P6KA30AHE3/73?
The HE3 suffix denotes RoHS-compliant construction with matte tin-plated leads that meet JESD 201 Class 2 whisker resistance requirements. It also confirms AEC-Q101 qualification and compliance with J-STD-002 solderability standards - critical for long-life, high-reliability deployments in sealed enclosures or high-temperature environments.
How does the P6KA30AHE3/73 differ from the non-A variant P6KA30HE3/73?
The P6KA30AHE3/73 has tighter VBR tolerance (28.5–31.5 V vs. 27.0–33.0 V for P6KA30HE3/73) and lower maximum clamping voltage (41.4 V vs. 43.5 V). This improved consistency supports more precise protection margins in regulated 24 V systems where voltage headroom is constrained.
Can the P6KA30AHE3/73 be used in bidirectional configurations?
No, the P6KA30AHE3/73 is unidirectional only, as explicitly stated in the Vishay datasheet. For AC or bipolar signal line protection, a dedicated bidirectional TVS such as P6SMB30CA must be selected - using two unidirectional devices in series anti-parallel is not recommended due to mismatched VBR and thermal imbalance risks.
