Product details
Overview
P6SMAJ70ADFQ-13 from Diodes Incorporated is an AEC-Q101 qualified 600W surface-mount transient voltage suppressor (TVS) diode in D-FLAT package, with 70V reverse standoff voltage, 77.8–89.5V breakdown range at 1mA, 113V clamping voltage at 5.3A peak pulse current, and optimized for automotive power line protection.
For engineers reviewing the P6SMAJ70ADFQ-13 datasheet, P6SMAJ70ADFQ-13 pinout, P6SMAJ70ADFQ-13 application, or P6SMAJ70ADFQ-13 equivalent, key selection criteria include clamping voltage margin vs. system rail, IPP derating under repetitive surge conditions, thermal resistance on FR-4 PCBs, and AEC-Q101 qualification status for under-hood deployment.
Technical Context
This unidirectional TVS diode operates as a shunt-type overvoltage protector, triggered when reverse voltage exceeds VRWM = 70V and clamping within 113V at IPP = 5.3A per 10/1000µs waveform. Its glass-passivated junction ensures stable breakdown and low leakage (<1µA at 70V).
Designed for automotive-grade reliability, it features IATF16949-certified manufacturing, PPAP capability, and thermal resistance of 92°C/W (junction-to-ambient on 0.4" × 0.5" copper pad), enabling robust operation from –55°C to +150°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W non-repetitive, supports single-event ESD/EFT surges up to 10/1000µs without failure |
| Clamping Voltage (VC) | 113V @ IPP = 5.3A - limits downstream IC stress during ISO 7637-2 Pulse 1/2a transients |
| Breakdown Voltage (VBR) | 77.8–89.5V @ IT = 1mA - ensures reliable triggering above 70V nominal rail with margin |
| Reverse Leakage (IR) | <1µA @ VRWM = 70V - negligible standby current impact on battery-powered modules |
| Thermal Resistance (RθJA) | 92°C/W on 0.4" × 0.5" 2oz Cu pad - enables sustained 1W dissipation at TA ≤ +85°C |
| Operating Temperature | –55°C to +150°C - validated for engine bay and transmission control unit environments |
Pinout & Package
Package: D-FLAT (surface-mount, low-profile, cathode-banded, 2-terminal device). Dimensions: 4.65mm × 2.80mm × 1.10mm max (L × W × H), weight ≈ 0.035g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Transient current sink node | Connected to protected line (e.g., 12V rail); carries full surge current to ground during clamping |
| 2 (Anode) | Reference / Ground return | Must be tied to low-impedance chassis or power ground plane to minimize VC overshoot |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Ensures stable VBR tolerance and long-term reliability under thermal cycling (–55°C/+150°C) |
| AEC-Q101 qualification | Validated for automotive use including HTOL, temperature cycling, and ESD testing per JESD22-A114 |
| D-FLAT low-profile package | Reduces board space by >40% vs. SMA while maintaining 600W surge rating and solder-reflow compatibility |
| Lead-free & halogen-free | Meets RoHS 3 (2015/863/EU) and "Green" definition: Br+Cl <1500ppm, Sb <1000ppm |
Applications
| Automotive Body Control Module (BCM) | Engine Control Unit (ECU) Power Input |
|---|---|
Use Scenario: Protects 12V supply input of BCM against load dump (ISO 7637-2 Pulse 5a) and alternator switching transients. IC Role / Device Role / Timing Role: Shunt TVS placed directly at connector entry point, clamping voltage before LDO regulators. Use Value: Limits transient voltage to ≤113V, preventing damage to 16V-rated input capacitors and PMICs. | Use Scenario: Safeguards ECU microcontroller power rails during cranking and cold-start conditions with high-voltage spikes. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main 12V feed, positioned upstream of bulk capacitance and DC-DC converters. Use Value: Withstands 600W peak pulses without degradation, ensuring functional safety compliance per ISO 26262 ASIL-B systems. |
| ADAS Camera Power Interface | Electric Power Steering (EPS) Motor Driver |
Use Scenario: Shields 5V/3.3V camera module power lines from coupled noise and ESD events in front-end harnesses. IC Role / Device Role / Timing Role: Secondary TVS stage after common-mode choke, targeting fast-rising ESD (IEC 61000-4-2 ±15kV contact). Use Value: Sub-1ns response time and <1µA leakage preserve signal integrity and battery life in always-on vision systems. | Use Scenario: Protects H-bridge gate drivers and current-sense amplifiers from inductive kickback during motor commutation. IC Role / Device Role / Timing Role: Bidirectional clamping (via external series diode) or unidirectional placement on low-side switch return path. Use Value: 5.3A IPP rating handles repetitive 10/1000µs surges typical in 48V EPS systems without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ70A | Same VRWM (70V), but SMB package (higher RθJA = 115°C/W), lower PPK = 600W only at TL = 25°C | Less suitable for high-ambient under-hood locations due to thermal limitations | Select if board space allows larger footprint and qualification beyond AEC-Q101 is not required |
| TPSMD70A | Higher clamping (124V @ 5.3A), same D-FLAT footprint, but not AEC-Q101 qualified | Acceptable for industrial controls but excluded from automotive PPAP documentation | Choose for cost-sensitive non-automotive designs where AEC-Q101 traceability is unnecessary |
Compared with SMBJ70A and TPSMD70A, P6SMAJ70ADFQ-13 uniquely combines AEC-Q101 qualification, D-FLAT thermal performance (92°C/W), and guaranteed 113V clamping - making it the only option qualified for PPAP-compliant automotive power rail protection where space and thermal headroom are constrained.

FAQ
What is the maximum allowable PCB pad size for optimal thermal performance?
The datasheet specifies two test conditions: 1" × 1" (RθJA = 115°C/W) and 0.4" × 0.5" (RθJA = 92°C/W) copper pads. For automotive applications, use the 0.4" × 0.5" layout with 2oz copper to achieve rated 92°C/W thermal resistance and sustain 1W steady-state dissipation at +85°C ambient.
Does P6SMAJ70ADFQ-13 support bidirectional transient suppression?
No - it is a unidirectional TVS diode. It protects against positive transients on the cathode side only. For bidirectional protection, pair it with a series diode or select a dedicated bidirectional variant such as P6SMBJ70CA; polarity is marked by a cathode band on the D-FLAT package top view.
How does its clamping voltage compare to competing 70V TVS devices?
At IPP = 5.3A, P6SMAJ70ADFQ-13 clamps at 113V - 11V lower than SMBJ70A (124V) and 4V lower than TPSMD70A (117V) under identical 10/1000µs conditions. This tighter clamping directly reduces stress on downstream 16V-rated capacitors and LDOs in automotive power domains.
Is PPAP documentation available for this part number?
Yes - P6SMAJ70ADFQ-13 is PPAP-capable and manufactured in IATF16949:2016 certified facilities. Aetrix Electronics provides full PPAP Level 3 documentation upon request, including PSW, design records, process flow diagrams, FMEA, control plans, and measurement system analysis reports.
