Product details
Overview
P6KE30AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary-level overvoltage protection of DC power rails and signal lines. It features 30 V breakdown voltage (VBR = 28.5–31.5 V at 1.0 mA), 41.4 V maximum clamping voltage (VC) at 14.5 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECUs, industrial I/O modules, and telecom power supplies.
For engineers reviewing the P6KE30AHE3/54 datasheet, P6KE30AHE3/54 pinout, P6KE30AHE3/54 application, or P6KE30AHE3/54 equivalent, this AEC-Q101 qualified device offers validated surge immunity for 12 V/24 V systems, low-leakage reverse operation (<1.0 µA at 25.6 V), and robust thermal performance up to +175 °C junction temperature - critical for under-hood and factory-floor deployments.
Technical Context
The P6KE30AHE3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to ESD and lightning-induced transients. Its unidirectional polarity uses cathode-band marking and exhibits forward voltage drop of 3.5 V at 50 A, supporting bidirectional surge suppression only when paired with complementary devices.
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), requiring minimum lead length (0.375") for rated 5.0 W power dissipation at TL = 75 °C. Derating begins above 25 °C ambient per Figure 2, with full derating to zero at 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 28.5–31.5 V at 1.0 mA - defines precise conduction onset threshold for reliable overvoltage triggering |
| Stand-off Voltage VWM | 25.6 V - maximum continuous reverse operating voltage without leakage exceeding 1.0 µA |
| Clamping Voltage VC | 41.4 V at 14.5 A IPPM - limits protected circuit voltage during 600 W transient events |
| Peak Pulse Power PPPM | 600 W (10/1000 µs) - sustains high-energy surges common in automotive load-dump and inductive switching |
| Operating Temperature Range | −55 °C to +175 °C - supports under-hood, industrial, and telecom environments without derating loss |
| AEC-Q101 Qualification | Qualified - validated for automotive electronics per stress test requirements including HTOL, TC, and HTRB |
| Package | DO-15 (DO-204AC) - industry-standard axial leaded package with UL 94 V-0 molded epoxy and matte tin plating |
Pinout & Package
DO-15 (DO-204AC) package: axial-leaded, cylindrical epoxy body (diameter 3.3–3.5 mm, length ≥25.4 mm), matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, with cathode band marking for unidirectional polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (non-banded end) | Forward current entry / reverse surge return path | Connects to lower-potential side of protected line; carries full surge current during clamping |
| Cathode (banded end) | Reverse-biased terminal / clamping node | Connected to higher-potential rail (e.g., +12 V); initiates avalanche conduction when VRM exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repetitive surge stress |
| 600 W peak pulse power (10/1000 µs) | Withstands automotive load-dump pulses (ISO 7637-2 Pulse 5a) without degradation |
| AEC-Q101 qualification | Validated for automotive-grade deployment including temperature cycling, high-temperature operating life, and bias-HAST |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., EFT IEC 61000-4-4) |
| UL 94 V-0 flammability rating | Molding compound prevents flame propagation in safety-critical enclosures per regulatory compliance |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |

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 | DO-214AC (SMA) package; 30 V VBR; 48.4 V VC at 12.3 A; 400 W PPPM | Surface-mount footprint; lower power rating; higher clamping voltage | Select for space-constrained PCBs where reflow compatibility and automated assembly are required |
| 1.5KE30A | DO-201AD package; identical VBR/VC specs; 1500 W PPPM; higher IFSM (200 A) | Through-hole but larger body; suited for higher-energy transients in industrial power systems | Choose when legacy 1.5 kW surge margin is mandated or where lead-forming flexibility is needed |

FAQ
What is the breakdown voltage tolerance for P6KE30AHE3/54?
The P6KE30AHE3/54 has a specified breakdown voltage range of 28.5 V to 31.5 V at 1.0 mA test current, representing ±5% tolerance around the nominal 30 V rating. This tight VBR window ensures consistent turn-on behavior across production lots and enables predictable system-level clamping design when used with P6KE30AHE3/54 in protection circuits.
Is P6KE30AHE3/54 suitable for bidirectional transient suppression?
No - P6KE30AHE3/54 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay specifies the "CA" variant (e.g., P6KE30CA). Using P6KE30AHE3/54 in AC or floating applications requires pairing with a second device or selecting the CA version to avoid forward conduction during negative transients.
What does the "HE3/54" suffix mean in P6KE30AHE3/54?
The "HE3" denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies packaging in 13-inch paper tape and reel with 4000 units per reel. This distinguishes P6KE30AHE3/54 from commercial-grade "E3" variants and confirms its suitability for automotive production environments requiring traceable, qualified components.
How does P6KE30AHE3/54 perform under elevated ambient temperatures?
P6KE30AHE3/54 follows standard derating per Figure 2: its 600 W peak pulse power is fully rated at 25 °C ambient and linearly decreases to zero at +175 °C junction temperature. At 85 °C ambient, P6KE30AHE3/54 retains ~75% of its surge capability - critical for engine bay or enclosed industrial controller deployments where thermal management is constrained.
Can P6KE30AHE3/54 replace P6KE30A-E3/54 in existing designs?
Yes - P6KE30AHE3/54 is a direct functional and mechanical replacement for P6KE30A-E3/54, sharing identical electrical specs, DO-15 package dimensions, and lead finish. The "H" prefix confirms AEC-Q101 qualification, adding automotive-grade reliability without layout or schematic changes; P6KE30AHE3/54 may be substituted where enhanced stress-test validation is required.
