Product details
Overview
P6SMAJ11ADFQ-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 11V reverse standoff voltage, 12.2–14.4V breakdown range at 1mA, 18.2V max clamping voltage at 33A peak pulse current, and is rated for -55°C to +150°C operation.
For engineers reviewing the P6SMAJ11ADFQ-13 datasheet, P6SMAJ11ADFQ-13 pinout, P6SMAJ11ADFQ-13 application, or P6SMAJ11ADFQ-13 equivalent, this device serves as a primary overvoltage clamp for 12V automotive subsystems-especially where space-constrained PCB layout, IATF16949-compliant manufacturing, and fast-response surge suppression are critical.
Technical Context
This unidirectional TVS diode operates in avalanche mode to clamp transient overvoltages above its breakdown threshold while maintaining low leakage (<1.0µA at 11V). Its glass-passivated junction ensures stable VBR tolerance and long-term reliability under repetitive surge stress.
The D-FLAT package enables low-inductance mounting with minimal board footprint and thermal resistance of 57°C/W (junction-to-terminal) on optimized 0.4" × 0.5" copper pads-critical for sustaining 600W non-repetitive pulses per the 10/1000µs waveform standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - Sustains single 10/1000µs transients without failure in automotive load-dump or ISO 7637-2 scenarios. |
| Reverse Standoff Voltage | 11V - Stable blocking threshold for nominal 12V systems; prevents conduction during normal operation. |
| Breakdown Voltage Range | 12.2–14.4V @ 1mA - Tight VBR window ensures predictable turn-on across temperature and unit variation. |
| Max Clamping Voltage | 18.2V @ 33A - Limits downstream IC voltage stress during 600W surges, protecting 24V-tolerant receivers. |
| Leakage Current | <1.0µA @ 11V - Negligible standby power loss and signal integrity impact in always-on modules. |
| Operating Temperature | -55°C to +150°C - Validated for under-hood and powertrain environments per AEC-Q101 stress testing. |
Pinout & Package
Package: D-FLAT (surface-mount, low-profile, cathode-banded); dimensions: 4.65mm × 2.80mm × 1.10mm (L × W × H), weight ≈ 0.035g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Transient Clamp Output | Connected to protected line (e.g., battery rail); sinks surge current to ground when VIN exceeds VBR. |
| 2 (Anode) | Reference / Ground Return | Connected to system ground plane; completes clamping path with minimal inductance via short, wide trace. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Ensures stable VBR and low parameter drift over 1000+ surge cycles and lifetime temperature cycling. |
| AEC-Q101 qualification & IATF16949 manufacturing | Validates suitability for automotive safety-critical ECUs, including body control, lighting, and ADAS power inputs. |
| Low-profile D-FLAT package | Reduces PCB area by >40% vs. SMA packages while enabling automated optical inspection (AOI) compatibility. |
| Lead-free, halogen- and antimony-free "Green" compliance | Meets RoHS 3 (2015/863/EU) and automotive ELV Directive requirements without compromising thermal performance. |
Applications
| Automotive Body Control Module (BCM) | Automotive Infotainment Power Input |
|---|---|
Use Scenario: Protects BCM microcontroller supply rails against load-dump transients (ISO 16750-2) and jump-start spikes. IC Role / Device Role: Primary unidirectional clamping element placed directly at 12V input connector. Use Value: Limits rail voltage to ≤18.2V during 600W surges, preventing latch-up or permanent damage to 24V-rated LDOs and CAN transceivers. | Use Scenario: Shields USB-C PD controller and display driver ICs from reverse-polarity and ESD events on vehicle accessory ports. IC Role / Device Role: First-stage overvoltage protector upstream of DC-DC converters and linear regulators. Use Value: Sub-1µA leakage preserves standby current budget; 11V standoff avoids false triggering during cold-crank (6.5–7V) conditions. |
| Automotive LED Headlamp Driver | Automotive Telematics Unit (TCU) Power Entry |
Use Scenario: Guards high-side MOSFET gate drivers and current-sense amplifiers from inductive kickback during PWM dimming. IC Role / Device Role: Localized clamp at driver IC supply pins to suppress <100ns ringing and overshoot. Use Value: 57°C/W RθJT enables direct thermal coupling to copper pour, sustaining repeated 33A pulses without derating. | Use Scenario: Secures LTE modem and GNSS receiver power inputs against ISO 7637-2 Pulse 1/2a/5a transients in connected car gateways. IC Role / Device Role: Front-end TVS in multi-stage protection network with downstream polymer PTC and ceramic capacitor. Use Value: 18.2V clamping aligns with 20V absolute maximum ratings of common PMICs, minimizing margin loss versus higher-VC alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-13-F | Same 11V standoff and 18.2V clamping, but SMA package (higher RθJA = 115°C/W) and no AEC-Q101 qualification. | Not approved for automotive production; suitable only for industrial or consumer prototypes. | Select only if cost sensitivity outweighs automotive compliance and thermal performance requirements. |
| 1.5SMC11A | Higher 1.5kW rating but larger SMC package (7.1mm × 6.2mm), 20.1V clamping at 75A, and no automotive qualification. | Over-specified for 12V systems; introduces unnecessary board area and cost in space-constrained modules. | Prefer only when legacy SMC footprint reuse is mandatory and 600W rating is insufficient. |
Compared with SMAJ11A-13-F and 1.5SMC11A, P6SMAJ11ADFQ-13 uniquely balances AEC-Q101 compliance, D-FLAT space efficiency, and precise 18.2V clamping-making it optimal for new automotive designs where PPAP readiness, thermal management, and footprint reduction are jointly prioritized.

FAQ
What is the polarity configuration of P6SMAJ11ADFQ-13?
P6SMAJ11ADFQ-13 is a unidirectional TVS diode with cathode (pin 1) and anode (pin 2) terminals. The cathode band marks pin 1, which connects to the protected line; the anode connects to ground. This configuration provides low-leakage blocking below 11V and rapid avalanche clamping above breakdown voltage.
How does P6SMAJ11ADFQ-13 perform under repeated surge stress?
Tested per IEC 61000-4-5 and ISO 7637-2, P6SMAJ11ADFQ-13 maintains clamping voltage stability and leakage integrity after ≥1000 pulses at 80% of rated peak power. Its glass-passivated die and D-FLAT thermal design ensure no parametric shift beyond ±5% over lifetime in automotive-grade thermal cycling (-40°C to +125°C).
Can P6SMAJ11ADFQ-13 be used in bidirectional configurations?
No-P6SMAJ11ADFQ-13 is strictly unidirectional. For bidirectional protection (e.g., AC lines or data buses), Diodes offers the P6SMBJ11CA-13 variant, which uses a back-to-back diode structure and has identical 11V standoff but symmetric ±18.2V clamping behavior.
What is the recommended PCB pad layout for optimal thermal performance?
Use the D-FLAT footprint specified in Diodes' package outline DS42231: 0.2" × 0.25" (5.08mm × 6.35mm) copper pads per terminal, with ≥2oz copper thickness and thermal vias to inner ground planes. This achieves the 57°C/W RθJT rating and prevents solder joint fatigue during thermal cycling.
