Product details
Overview
P6SMAJ75ADF-13 from Diodes Incorporated is a 600W surface-mount transient voltage suppressor (TVS) diode designed for unidirectional overvoltage protection in DC power lines and signal interfaces. It features a reverse standoff voltage of 75.0 V, breakdown voltage range of 83.3–95.8 V at 1.0 mA test current, clamping voltage of 121.0 V at 4.9 A peak pulse current, and D-FLAT package for space-constrained PCB layouts-commonly used in industrial power supply input stages.
For engineers reviewing the P6SMAJ75ADF-13 datasheet, P6SMAJ75ADF-13 pinout, P6SMAJ75ADF-13 application, or P6SMAJ75ADF-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VMAX, peak pulse current capability under 10/1000 µs surge, thermal resistance on FR-4 board, polarity marking (cathode band), and RoHS-compliant matte tin termination.
Technical Context
This unidirectional TVS operates in avalanche breakdown mode to clamp transient voltages above its standoff threshold. Its glass-passivated die ensures stable leakage performance (<1.0 µA at 75 V) and fast response time (<1.0 ns), enabling suppression of ESD (IEC 61000-4-2) and lightning-induced surges (IEC 61000-4-5).
The device is rated for 600 W non-repetitive peak pulse power per 10 × 1000 µs waveform, with thermal resistance of 92 °C/W (junction-to-ambient, small pad layout) and 57 °C/W (junction-to-terminal), requiring careful copper pour design to sustain repeated transients without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - Sustains single 10/1000 µs surges up to this energy level without failure |
| Reverse Standoff Voltage (VRWM) | 75.0 V - Maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 83.3–95.8 V @ 1.0 mA - Confirmed avalanche initiation range; defines minimum clamping onset |
| Clamping Voltage (VC) | 121.0 V @ 4.9 A - Maximum voltage seen by downstream circuit during specified surge |
| Peak Pulse Current (IPP) | 4.9 A - Peak current delivered under 10/1000 µs waveform at rated clamping voltage |
| Reverse Leakage (IR) | <1.0 µA @ 75 V - Ensures minimal standby power loss and signal integrity in high-impedance nodes |
| Package | D-FLAT - Low-profile (1.1 mm max height), 2-pin surface-mount package with cathode band marking |
Pinout & Package
Package: D-FLAT, molded plastic case (UL 94V-0), 0.035 g weight, matte tin annealed terminals, cathode band polarity indicator. Dimensions: 4.60 × 2.95 × 1.10 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Transient current sink | Connected to protected line; conducts avalanche current to ground during overvoltage event |
| 2 (Anode) | Reference node | Typically tied to system ground; completes current path during clamping operation |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Ensures stable VBR tolerance and low leakage across temperature and lifetime |
| 600 W peak pulse rating | Supports robust protection against IEC 61000-4-5 Level 3 (1 kV/2 Ω) surges on 24 V/48 V industrial buses |
| Low-profile D-FLAT package | Reduces board area by >40% vs. SMA; enables routing under connectors or tight spacing near I/O ports |
| RoHS & halogen-free compliance | Meets EU RoHS 2 and green manufacturing requirements (<900 ppm Br/Cl, <1000 ppm Sb) |
Applications
| Industrial PLC I/O Protection | DC Power Input Stage |
|---|---|
Use Scenario: Protecting 24 V digital input channels in programmable logic controllers against field-wiring induced surges and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input terminal and ground, clamping transients before they reach optocoupler or MCU GPIO. Use Value: Clamping voltage of 121.0 V ensures safe margin below 150 V-rated input protection circuits while maintaining <1.0 µA leakage at nominal 24 V. | Use Scenario: Safeguarding switching regulator inputs in DIN-rail power supplies exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 48 V DC input rail, coordinated with upstream fuse and downstream LC filter. Use Value: 600 W rating handles 10/1000 µs surges up to 4.9 A without degradation, supporting EN 61000-4-5 compliance testing. |
| Telecom Line Interface | Automotive Body Control Module |
Use Scenario: Transient suppression on RS-485 data lines in outdoor base station cabinets subject to lightning-induced coupling. IC Role / Device Role / Timing Role: Unidirectional TVS on differential pair (A/B lines), referenced to local ground plane with low-inductance layout. Use Value: Fast response (<1 ns) and 121.0 V clamping prevent damage to isolated transceivers rated for ±15 V common-mode range. | Use Scenario: Protecting LIN bus nodes and sensor inputs in body control modules subjected to battery disconnect transients. IC Role / Device Role / Timing Role: TVS mounted directly at connector entry point, shunting ISO 7637-2 Pulse 1 (−100 V/50 Ω) energy to chassis ground. Use Value: 75 V standoff matches typical 12 V automotive systems with 25% derating margin; D-FLAT footprint allows placement adjacent to sealed connectors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ75A-Q | Same 75 V VRWM, but 400 W rating and higher clamping voltage (125 V @ 4.0 A); JEDEC-standard SMA package | Lower power handling limits use in high-energy surge environments; larger SMA footprint requires more board area | Select when legacy SMA layout exists and 400 W suffices; avoid where 600 W margin is required for long-term reliability |
| 1.5SMC75A | Same 75 V rating, 1500 W rating, DO-214AB package; higher thermal mass but 2× footprint size | Overqualified for most 24/48 V applications; better suited for primary AC input protection or high-current battery systems | Choose only if surge energy exceeds 600 W or board layout accommodates larger SMC outline; otherwise adds unnecessary cost and area |
Compared with SMAJ75A-Q and 1.5SMC75A, P6SMAJ75ADF-13 delivers optimal balance of 600 W surge capacity, compact D-FLAT footprint, and precise 121.0 V clamping-making it ideal for space-constrained industrial and telecom DC interfaces where both performance and layout efficiency matter.

FAQ
What is the maximum operating temperature for P6SMAJ75ADF-13?
The device supports an operating junction temperature range of −55 °C to +150 °C. Its thermal resistance is 92 °C/W (junction-to-ambient on small-pad FR-4) and 57 °C/W (junction-to-terminal), meaning sustained 600 W pulses require adequate copper pour or heatsinking to avoid exceeding 150 °C junction limit.
Is P6SMAJ75ADF-13 bidirectional or unidirectional?
P6SMAJ75ADF-13 is a unidirectional TVS diode, indicated by its single cathode band marking and electrical specification table listing only reverse standoff and breakdown parameters. It protects against positive transients on the cathode side relative to anode (ground), not symmetrical AC surges.
How does the D-FLAT package affect PCB layout compared to SMA?
The D-FLAT package measures 4.60 × 2.95 × 1.10 mm-approximately 30% shorter and 25% narrower than standard SMA-and uses a flat bottom for improved thermal conduction. Its pad layout requires tighter spacing (0.2" × 0.25" recommended copper) and benefits from solder mask defined pads to prevent bridging.
Can P6SMAJ75ADF-13 be used in automotive applications?
Yes, it meets AEC-Q200 stress test recommendations for TVS diodes and is rated for −55 °C to +150 °C operation. Its 75 V standoff aligns with 12 V automotive systems (with 25% margin), and its 600 W rating covers ISO 7637-2 Pulse 1 and Pulse 2a transients when properly mounted with low-inductance grounding.
