Product details
Overview
P6SMAJ64ADFQ-13 from Diodes Incorporated is an AEC-Q101 qualified, 600W surface-mount transient voltage suppressor (TVS) diode in D-FLAT package, designed for automotive power line protection. It features a 64V reverse standoff voltage, 71.1–81.8V breakdown range at 1mA, 103V clamping voltage at 5.8A peak pulse current, and <1µA leakage at rated VRWM - deployed in engine control units, infotainment power rails, and ADAS sensor interfaces.
For engineers reviewing the P6SMAJ64ADFQ-13 datasheet, P6SMAJ64ADFQ-13 pinout, P6SMAJ64ADFQ-13 application, or P6SMAJ64ADFQ-13 equivalent, this page delivers verified electrical specs, thermal resistance values (RθJT = 57°C/W on 0.4"×0.5" PCB), automotive qualification status, and real-world use context for ESD/surge protection design-in.
Technical Context
This unidirectional TVS diode operates as a clamping device in parallel with sensitive electronics, conducting only during overvoltage transients above its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5% typical), fast response time (<1ps), and robust surge handling per IEC 61000-4-5 (10/1000µs waveform).
The D-FLAT package enables low-inductance layout critical for high-speed transient suppression. Thermal performance is defined for two PCB mounting conditions: RθJA = 92°C/W on 0.4"×0.5" copper pad and RθJT = 57°C/W to terminal - enabling accurate junction temperature estimation under pulsed load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (non-repetitive, 10×1000µs waveform - defines maximum transient energy absorption) |
| Reverse Standoff Voltage | 64V (maximum continuous DC or RMS voltage before significant leakage - sets operating margin) |
| Breakdown Voltage | 71.1–81.8V @ 1mA (guaranteed conduction onset range - determines clamping trigger point) |
| Clamping Voltage | 103V @ 5.8A IPP (maximum voltage seen by protected circuit during surge - directly limits stress) |
| Leakage Current | <1µA @ 64V (minimal standby power loss and signal integrity impact in always-on systems) |
| Thermal Resistance | RθJT = 57°C/W (junction-to-terminal - enables accurate thermal design on compact automotive PCBs) |
| AEC-Q101 Qualified | Yes (validated for automotive-grade reliability including temperature cycling, HTRB, and ESD) |
Pinout & Package
Package: D-FLAT (low-profile surface-mount, 2-pin, cathode-banded, 0.9–1.1mm height, 2.25–2.95mm width, 3.95–4.60mm length).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Transient current sink path | Connected to protected line; conducts surge current to ground when clamped |
| 2 (Anode) | Reference/ground return | Typically tied to system ground plane; completes low-inductance discharge path |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Supports IEC 61000-4-5 Level 4 (4kV) surge immunity on 12V automotive power nets |
| Glass-passivated die | Ensures long-term VBR stability and reduced parameter drift across temperature and life cycles |
| D-FLAT low-profile package | Reduces parasitic inductance vs. SMA/SMB, improving clamping speed and high-frequency transient response |
| AEC-Q101 qualification | Validated for automotive under-hood and cabin environments (-55°C to +150°C TJ) |
| Halogen- and antimony-free | Meets automotive "Green" requirements (<900ppm Br/Cl, <1000ppm Sb - supports end-of-life recycling) |
Applications
| Engine Control Unit (ECU) Power Input | Infotainment System USB Power Rail |
|---|---|
Use Scenario: Protects 12V supply input of engine control modules against load dump and alternator ripple surges. IC Role / Device Role: Unidirectional TVS clamping device placed between battery rail and LDO input. Use Value: Limits transient voltage to ≤103V, preventing damage to downstream 3.3V/5V regulators and microcontrollers. |
Use Scenario: Shields USB VBUS line in head unit against hot-plug ESD and cable-induced transients. IC Role / Device Role: Low-capacitance TVS (CT ≈ 100pF @ 0V) shunted across VBUS and GND. Use Value: Clamps 8kV contact ESD per IEC 61000-4-2 without signal distortion or data corruption. |
| ADAS Camera Module Power Line | Body Control Module (BCM) LIN Bus Interface |
Use Scenario: Safeguards 5V camera sensor power rail against ignition noise and ISO 7637-2 pulse 5a/b. IC Role / Device Role: Primary surge suppressor upstream of DC-DC converter and image sensor IC. Use Value: Withstands 600W pulses while maintaining <1µA leakage - avoids dark current increase in CMOS sensors. |
Use Scenario: Protects LIN transceiver VCC pin from battery transients during vehicle jump-start events. IC Role / Device Role: Secondary TVS on 12V supply side of LIN bus regulator (not on data line). Use Value: Fast clamping (sub-nanosecond) prevents regulator latch-up and maintains LIN communication integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-Q | Same 64V VRWM, but non-automotive grade; no AEC-Q101 qualification or PPAP support | Limited to industrial/commercial designs without automotive change control requirements | Select when cost sensitivity outweighs automotive compliance needs and supply chain traceability is not mandated |
| 1.5SMC64A | Higher RθJA (115°C/W), larger SMC package (7.1×6.2mm vs. D-FLAT's 4.6×2.8mm), same 103V VC | Requires more board space; less suitable for dense automotive modules with strict height constraints | Prefer for legacy industrial designs where footprint and thermal derating margins allow larger package |
Compared with SMAJ64A-Q and 1.5SMC64A, P6SMAJ64ADFQ-13 uniquely combines AEC-Q101 qualification, D-FLAT space efficiency, and 57°C/W junction-to-terminal thermal resistance - making it optimal for next-gen automotive ECUs and ADAS modules requiring both reliability and miniaturization.

FAQ
What is the maximum clamping voltage of P6SMAJ64ADFQ-13 at its rated peak pulse current?
The maximum clamping voltage (VC) is 103V at 5.8A peak pulse current (IPP), measured using the standardized 10×1000µs waveform per IEC 61000-4-5. This value is guaranteed across the full operating temperature range (-55°C to +150°C) and defines the upper voltage limit imposed on protected circuits during surge events.
Is P6SMAJ64ADFQ-13 suitable for bidirectional transient suppression?
No - P6SMAJ64ADFQ-13 is a unidirectional TVS diode, optimized for clamping positive transients on DC power lines with defined polarity. For AC or bidirectional signal line protection, a dedicated bidirectional variant (e.g., P6SMBJ64CA) must be used, as this part lacks symmetrical breakdown characteristics.
How does the D-FLAT package improve surge protection performance compared to SMA?
The D-FLAT package reduces lead inductance by ~40% versus standard SMA due to shorter internal bond wires and planar terminal geometry. This lowers the effective clamping voltage during fast-rising transients (e.g., ESD), improves high-frequency energy dissipation, and enables tighter placement near connectors - critical for meeting ISO 10605 and IEC 61000-4-2 requirements.
What is the steady-state power dissipation rating for P6SMAJ64ADFQ-13?
The steady-state power dissipation (PM(AV)) is 1.0W at TL = +25°C. This rating applies only to continuous DC or low-frequency AC conditions - not transient events. In practice, the device remains thermally safe under normal operation due to sub-microamp leakage, but sustained overvoltage beyond VRWM will cause thermal runaway and failure.
