Product details
Overview
P6SMAJ36ADFQ-13 from Diodes Incorporated is an AEC-Q101 qualified, 600W surface-mount transient voltage suppressor (TVS) diode in the D-FLAT package, designed for automotive power line and signal line protection. It features a 36V reverse standoff voltage, 40–46V breakdown range at 1mA, 58.1V clamping voltage at 10.3A peak pulse current, and is optimized for ESD and surge immunity in 12V/24V vehicle subsystems including body control modules and infotainment interfaces.
For engineers reviewing the P6SMAJ36ADFQ-13 datasheet, P6SMAJ36ADFQ-13 pinout, P6SMAJ36ADFQ-13 application, or P6SMAJ36ADFQ-13 equivalent, this device delivers verified automotive-grade transient suppression with low clamping ratio (VC/VRWM ≈ 1.61), fast response time (<1 ns), and IATF16949-certified manufacturing - critical for CAN bus node protection, LIN transceiver input hardening, and DC-DC converter input rail safeguarding.
Technical Context
This unidirectional TVS diode operates as a shunt-type overvoltage protector, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5% typical), low leakage (<1 µA at VRWM), and robust surge handling per IEC 61000-4-5 (10/1000 µs waveform).
The D-FLAT package enables high thermal efficiency with RθJA = 92°C/W on compact 0.4" × 0.5" PCB pads, supporting continuous operation from –55°C to +150°C. Its 3.5V forward voltage at 35A confirms low-conduction loss during bidirectional surge events, while cathode-band polarity marking ensures unambiguous board-level orientation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - Sustains single 10×1000 µs surges up to 600W without degradation under defined thermal conditions. |
| Reverse Standoff Voltage | 36 V - Maximum continuous DC or RMS voltage the device blocks before entering avalanche conduction. |
| Breakdown Voltage | 40.0–46.0 V @ 1 mA - Tight VBR window ensures predictable turn-on across temperature and production lot. |
| Clamping Voltage | 58.1 V @ 10.3 A - Limits downstream circuit voltage to ≤58.1V during worst-case 10.3A transient, enabling safe IC interface design. |
| Peak Pulse Current | 10.3 A - Maximum non-repetitive surge current the device safely clamps per IEC 61000-4-5 waveform. |
| Junction Temperature Range | –55°C to +150°C - Fully rated for under-hood automotive environments and industrial control enclosures. |
| Thermal Resistance (J-A) | 92 °C/W - Measured on 0.4" × 0.5", 2 oz copper pad; enables accurate thermal margining in space-constrained layouts. |
Pinout & Package
Package: D-FLAT (low-profile surface-mount), molded plastic case with UL 94V-0 flammability rating, matte tin annealed terminals, cathode band polarity indicator, and approximate weight of 0.035 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Transient current sink node | Connected to protected line; conducts avalanche current to ground during overvoltage events. |
| 2 (Anode) | Reference / ground return | Typically tied to system ground plane; completes clamping path and defines polarity for unidirectional operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use with PPAP capability and IATF16949-certified manufacturing - eliminates requalification effort for Tier 1 designs. |
| Glass-passivated die | Ensures long-term parameter stability and resistance to humidity-induced leakage drift in harsh environments. |
| Low-profile D-FLAT package | 0.9–1.1 mm height enables placement beneath connectors or near edge-mounted components without mechanical interference. |
| RoHS 3 & "Green" compliance | <900 ppm Br, <900 ppm Cl, <1000 ppm Sb - meets global environmental mandates without compromising surge performance. |
| Fast response time | <1 ns turn-on latency - clamps transients before sensitive logic or analog circuitry sustains damage. |
Applications
| Automotive Body Control Module (BCM) | Infotainment System Power Input |
|---|---|
Use Scenario: Protects 12V supply inputs of BCM microcontrollers and driver ICs against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Shunt clamping element placed directly at power entry point before DC-DC regulators. Use Value: Limits voltage excursion to ≤58.1V during 10.3A transients, preserving regulator input ratings and preventing brownout resets. |

IC Role / Device Role / Timing Role: Paired unidirectional TVS on each differential line, referenced to common ground. Use Value: Low capacitance (<100 pF at 0V bias) prevents signal integrity degradation at 5 Mbps CAN FD data rates. |
Use Scenario: Secures 24V auxiliary power input of wireless sensor nodes deployed in factory automation cabinets. IC Role / Device Role / Timing Role: Primary overvoltage clamp upstream of isolated DC-DC converter and LDO. Use Value: Withstands repeated 600W surges per IEC 61000-4-5 Level 4, extending field service life beyond 10 years. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-Q | Same 36V VRWM and 58.1V VC, but not AEC-Q101 qualified; RθJA = 115°C/W (larger pad required). | Limited to commercial/industrial use; unsuitable for PPAP-submitted automotive programs. | Select only if automotive qualification and IATF16949 traceability are not required. |
| 1.5SMC36AQ | Higher 1500W rating, DO-214AB package (larger footprint), VF = 3.5V same, but 2.5× higher RθJA (210°C/W). | Better energy handling but incompatible with space-constrained D-FLAT layouts; requires redesign of PCB area and thermal relief. | Choose when surge energy exceeds 600W but board real estate allows larger package. |
Compared with SMAJ36A-Q and 1.5SMC36AQ, P6SMAJ36ADFQ-13 uniquely balances automotive qualification, low-profile D-FLAT packaging, and 600W capability - making it optimal for next-gen ADAS domain controllers and compact ECU designs where space, reliability, and compliance are jointly constrained.

FAQ
What is the maximum operating temperature for P6SMAJ36ADFQ-13?
The device is rated for continuous operation from –55°C to +150°C junction temperature. This range is validated per AEC-Q101 stress testing and supports under-hood deployment in engine control units and transmission control modules without derating.
Is P6SMAJ36ADFQ-13 unidirectional or bidirectional?
P6SMAJ36ADFQ-13 is a unidirectional TVS diode, configured with cathode and anode terminals. Its schematic symbol and datasheet test conditions (reverse-biased clamping) confirm operation only in reverse avalanche mode - it does not conduct in forward direction beyond VF ≈ 3.5V.
Does this part require external heat sinking?
No external heat sink is required. The D-FLAT package achieves RθJA = 92°C/W on a 0.4" × 0.5" 2 oz copper pad, sufficient for steady-state dissipation of 1.0 W. Thermal design should follow Diodes' recommended pad layout and avoid solder mask over thermal pads.
How does P6SMAJ36ADFQ-13 differ from standard SMAJ36A?
Unlike standard SMAJ36A, P6SMAJ36ADFQ-13 adds AEC-Q101 qualification, PPAP readiness, IATF16949 manufacturing, tighter VBR tolerance, and enhanced moisture sensitivity level (MSL 1). It also uses a D-FLAT package instead of DO-214AC, reducing height by ~0.5 mm for ultra-thin automotive modules.
