Overview
P6KA36AHE3/53 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 34.2 V to 37.8 V breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), 12.0 A peak pulse current (IPPM), and clamps to ≤49.9 V at rated surge - deployed in automotive power rails, industrial sensor interfaces, and telecom DC inputs.
For engineers reviewing the P6KA36AHE3/53 datasheet, P6KA36AHE3/53 pinout, P6KA36AHE3/53 application, or P6KA36AHE3/53 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, DO-15 package dimensions, clamping behavior under surge, and direct alternatives for circuit-level ESD/surge hardening.
Technical Context
This TVS operates as a silicon avalanche diode with passivated anisotropic rectifier technology, enabling stable clamping across -65 °C to +185 °C junction temperature. Its unidirectional polarity and low incremental surge resistance ensure fast response (<1 ns) and minimal voltage overshoot during 10/1000 μs transients.
The device complies with ANSI/IEEE C62.35 surge standards and is rated for repetitive 0.01% duty cycle pulses. Its 185 °C maximum junction temperature and JESD201 Class 2 whisker-tested matte tin leads support high-reliability automotive and industrial deployments where thermal cycling and long-term solder joint integrity are critical.

|---|---|
Use Scenario: 12 V/24 V battery line in engine control units exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground to clamp surges before they reach MCU power pins or LDO inputs. Use Value: Limits transient voltage to ≤49.9 V, protecting 3.3 V/5 V logic supplies via downstream regulators while surviving 185 °C under-hood ambient. |
Use Scenario: 4–20 mA current loop or RS-485 bus in factory automation sensors subject to EFT (IEC 61000-4-4) and lightning-induced coupling. IC Role / Device Role / Timing Role: TVS mounted across differential pair or single-ended analog input to shunt fast transients before op-amp or ADC front-end. Use Value: Sub-1 ns response and 12.0 A IPPM capability suppress >1 kV EFT bursts without latch-up or parametric shift in precision signal chain. |
| Telecom DC Input Surge Suppression | Consumer Power Adapter Output Clamping |
Use Scenario: 48 V PoE-powered equipment (e.g., IP cameras) receiving surges from Ethernet cabling or shared DC distribution. IC Role / Device Role / Timing Role: Primary TVS on DC input stage upstream of DC-DC converter, configured in unidirectional mode to handle positive-going surges only. Use Value: 600 W rating and 30.8 V VWM allow compatibility with 48 V nominal systems while clamping below 50 V to preserve converter overvoltage protection thresholds. |
Use Scenario: Secondary-side 5 V/12 V output of wall adapters used in smart home hubs, where user-accessible ports risk ESD contact discharge. IC Role / Device Role / Timing Role: Final-stage TVS on regulated output rail to absorb ±8 kV contact ESD (IEC 61000-4-2) before reaching USB ports or SoC VDD pins. Use Value: Low leakage (<1 μA at 30.8 V) prevents standby current degradation; DO-15 form factor allows manual rework and cost-effective through-hole assembly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/5A | Same DO-214AC (SMA) package; 36.0–40.0 V VBR, 40.2 V VC, 400 W PPPM, 10.3 A IPPM | Lower power rating and smaller footprint; suited for space-constrained PCBs but requires higher layout density control. | Select when board area is limited and 400 W surge immunity suffices; verify thermal relief for 185 °C operation is maintained. |
| 1.5KE36A | DO-201AD package; 36.0–40.0 V VBR, 49.9 V VC, 1500 W PPPM, 30.1 A IPPM, 175 °C TJ max | Higher surge capacity but larger body (5.6 mm Ø); not AEC-Q101 qualified; lacks whisker-tested leads. | Choose for non-automotive 1500 W surge needs where DO-201AD mounting is acceptable and lifetime whisker risk is not mandated. |
Compared with SMAJ36A-E3/5A, P6KA36AHE3/53 offers 50% higher surge power and AEC-Q101 assurance; versus 1.5KE36A, it trades peak power for automotive qualification, tighter thermal margin, and proven long-term solder reliability - making it optimal for safety-critical embedded systems.

FAQ
What is the maximum clamping voltage of the P6KA36AHE3/53 at its rated peak pulse current?
The P6KA36AHE3/53 has a maximum clamping voltage (VC) of 49.9 V when subjected to its rated 12.0 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream components see no more than 49.9 V during standardized surge events - critical for safeguarding 3.3 V, 5 V, or 12 V IC supplies. The P6KA36AHE3/53 achieves this with low incremental surge resistance and stable avalanche characteristics across its full temperature range.
Is the P6KA36AHE3/53 qualified for automotive applications?
Yes, the P6KA36AHE3/53 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated temperature-humidity stress (HAST). Its 185 °C maximum junction temperature, JESD201 Class 2 whisker-tested matte tin leads, and DO-15 mechanical robustness make it suitable for engine bay, body control module, and ADAS power rail protection. The P6KA36AHE3/53 meets automotive reliability requirements without derating up to its full rated specifications.
What does the "HE3/53" suffix indicate in P6KA36AHE3/53?
The "HE3/53" suffix in P6KA36AHE3/53 specifies RoHS-compliant packaging and tape-and-reel delivery: HE3 denotes matte tin-plated leads meeting J-STD-002 and JESD22-B102 solderability standards plus JESD201 Class 2 whisker resistance, while /53 indicates 500-piece quantity in 7" diameter paper tape and reel. This packaging format ensures compatibility with automated SMT placement equipment and supports high-volume manufacturing - a key requirement for the P6KA36AHE3/53 in automotive and industrial production lines.
How does the P6KA36AHE3/53 differ from the non-A version (P6KA36HE3/53)?
The P6KA36AHE3/53 has tighter VBR tolerance (34.2–37.8 V) versus P6KA36HE3/53 (32.4–39.6 V), resulting in more precise clamping onset and reduced variation in system-level surge response. It also exhibits lower maximum leakage current (1.0 μA at VWM) compared to 5.0 μA for the non-A variant, improving efficiency in low-power always-on circuits. These differences make the P6KA36AHE3/53 preferable for designs demanding tighter voltage control and ultra-low standby loss - both confirmed in the official Vishay datasheet revision 20-Dec-13.
Can the P6KA36AHE3/53 be used in bidirectional configurations?
No, the P6KA36AHE3/53 is strictly unidirectional and must be installed with cathode toward the higher-potential side of the protected line. It does not provide symmetrical clamping for AC or bipolar transients. For bidirectional protection, two P6KA36AHE3/53 devices may be connected in series opposing configuration, but this increases forward voltage drop and requires careful layout to avoid parasitic inductance. Vishay does not specify or characterize the P6KA36AHE3/53 for reverse-biased conduction - its design and qualification are exclusively for unidirectional surge suppression.
