Product details
Overview
P6SMAJ7.0ADF from Diodes Incorporated is a 600W surface-mount transient voltage suppressor (TVS) diode designed for unidirectional overvoltage protection in DC power rails and signal lines. It features a 7.0V reverse standoff voltage, 7.78–8.95V breakdown range at 10mA, 12.0V max clamping voltage at 50A peak pulse current, and D-FLAT package for space-constrained PCB layouts-used in industrial power supplies and automotive body control modules.
For engineers reviewing the P6SMAJ7.0ADF datasheet, P6SMAJ7.0ADF pinout, P6SMAJ7.0ADF application, or P6SMAJ7.0ADF equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, peak pulse current handling under IEC 61000-4-5 surge, thermal resistance on FR-4 pads, and RoHS/Green compliance for automotive-grade production.
Technical Context
This unidirectional TVS diode operates in avalanche breakdown mode to clamp transient voltages above its standoff threshold. Its glass-passivated junction ensures stable leakage (<200µA at 7.0V) and repeatable breakdown behavior across temperature (-55°C to +150°C).
The device responds within <1ns to fast transients (per 10/1000µs waveform), delivering 600W peak pulse power dissipation with 50A maximum IPP. Thermal resistance is 57°C/W (junction-to-terminal) when mounted on a 0.4" × 0.5" 2oz copper pad-critical for sustained surge duty cycles in motor drive gate drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 10/1000µs surges without failure under defined board layout |
| Reverse Standoff Voltage (VRWM) | 7.0V - maximum continuous DC voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 7.78–8.95V @ 10mA - guaranteed conduction onset window for design margining |
| Max Clamping Voltage (VC) | 12.0V @ 50A - limits downstream IC stress during worst-case surge events |
| Peak Pulse Current (IPP) | 50.0A - peak current it can divert while maintaining specified VC |
| Package | D-FLAT - 2-pin, low-profile surface-mount outline (4.65mm × 2.80mm) with cathode band polarity indicator |
| RoHS & Green Compliance | Lead-free, halogen-free, antimony-free - meets EU RoHS 2 and Diodes Inc. "Green" definition (<900ppm Br/Cl, <1000ppm Sb) |
Pinout & Package
Package: D-FLAT - molded plastic case (UL 94V-0), 0.035g weight, matte tin annealed terminals, cathode band marking. Dimensions: 4.65mm × 2.80mm × 1.10mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Anode of internal PN junction | Connected to protected line; clamps positive transients to ground when reverse-biased |
| 2 (Anode) | Cathode of internal PN junction | Typically tied to system ground; completes current path during surge conduction |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile D-FLAT package | Reduces board area by >40% vs. SMA; enables high-density routing in compact power modules |
| Glass-passivated die construction | Ensures long-term parameter stability and immunity to humidity-induced leakage drift |
| 600W peak pulse rating | Supports IEC 61000-4-5 Level 4 (4kV) surge testing on 12V automotive supply rails |
| Fast response time (<1ns) | Clamps ESD and lightning-induced spikes before sensitive logic or analog circuitry is damaged |
| Halogen- and antimony-free "Green" material set | Meets automotive OEM environmental requirements (e.g., Ford WSS-M99P33-A2, GM GP-10) |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A | Same electrical specs but SMA package (higher profile, 4.5mm × 2.7mm); RθJA = 115°C/W vs. 92°C/W for D-FLAT | Less suitable for ultra-thin designs or high-power density boards where thermal relief is constrained | Select when legacy SMA footprint compatibility is required and board thickness allows |
| P6SMBJ7.0A | 600W rating, same VRWM/VC, but SMB package (4.6mm × 3.95mm); 10% larger footprint and 15% higher RθJA | Lower current density handling in compact layouts due to reduced copper pad area efficiency | Prefer only if existing SMB land pattern must be reused and thermal margin exceeds 20°C |
Compared with SMAJ7.0A and P6SMBJ7.0A, P6SMAJ7.0ADF delivers superior thermal performance in space-limited applications via its D-FLAT package's lower junction-to-terminal resistance (57°C/W), enabling higher surge repetition rates in motor control gate drivers.

FAQ
What is the maximum operating temperature for P6SMAJ7.0ADF?
The P6SMAJ7.0ADF is rated for continuous operation from –55°C to +150°C junction temperature. Its thermal resistance (RθJT = 57°C/W) means that at 50A peak pulse current, junction temperature rise remains within safe limits when mounted on a 0.4" × 0.5" 2oz copper pad-critical for under-hood automotive applications.
How does P6SMAJ7.0ADF differ from P6SMAJ7.0A?
P6SMAJ7.0ADF and P6SMAJ7.0A are identical electrically and mechanically-the "D" suffix denotes Diodes Incorporated's standard green-compliant packaging (halogen/antimony-free), while "A" indicates earlier RoHS-compliant versions. Both share the same D-FLAT package, 7.0V VRWM, and 12.0V VC; no functional or reliability difference exists.
Can P6SMAJ7.0ADF be used in bidirectional configurations?
No-P6SMAJ7.0ADF is a unidirectional TVS diode with cathode-anode polarity. For bidirectional protection (e.g., AC lines or differential data buses), use the complementary P6SMAJ7.0CA part, which integrates two opposing diodes in one D-FLAT package and provides symmetrical clamping around 0V.
What is the typical total capacitance of P6SMAJ7.0ADF at 0V bias?
While not explicitly listed for P6SMAJ7.0ADF in DS38930, the series exhibits typical capacitance of ~650pF at 0V bias and 1MHz for the 7.0V variant (interpolated from Fig. 2 curve showing ~750pF at 5V and ~500pF at 10V). This value impacts high-speed signal line protection and should be verified with bench measurement for USB or CAN applications.
