Product details
Overview
P6SMAJ6.5ADFQ-13 from Diodes Incorporated is an AEC-Q101 qualified, 600W surface-mount transient voltage suppressor (TVS) diode in the D-FLAT package, designed for automotive power line and signal line protection. It features a 6.5V reverse standoff voltage, 7.22–8.30V breakdown range at 10mA, 11.2V max clamping voltage at 53.6A peak pulse current, and is rated for -55°C to +150°C operation.
For engineers reviewing the P6SMAJ6.5ADFQ-13 datasheet, P6SMAJ6.5ADFQ-13 pinout, P6SMAJ6.5ADFQ-13 application, or P6SMAJ6.5ADFQ-13 equivalent, this device is selected for robust ESD and surge immunity in 12V automotive subsystems where low-profile mounting, fast response (<1ns), and IATF16949-certified manufacturing are required.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping protector: under normal bias it presents high impedance (>1MΩ at 5V), but triggers into low-impedance conduction when reverse voltage exceeds VBR, limiting transient energy with 600W peak pulse power handling per 10/1000µs waveform. Its glass-passivated junction ensures stable leakage performance across temperature.
The D-FLAT package enables thermal dissipation via copper pad layout (RθJA = 92°C/W on 0.4"×0.5" FR-4), supporting sustained 1.0W steady-state power at TL = +25°C. Polarity is marked by cathode band; terminals are matte tin annealed over copper lead-frame for reliable solderability.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.5A-Q | Same D-FLAT package, identical electrical specs, but not AEC-Q101 qualified | Approved only for industrial/commercial use; lacks PPAP documentation and IATF16949 traceability | Select when automotive qualification is not required and cost sensitivity is higher |
| 1.5SMC6.5A | Higher 1500W rating, DO-214AB package (larger footprint), 11.3V clamping at 133A | Used in non-space-constrained designs needing higher surge margin; incompatible pinout | Choose when board space allows larger package and system requires >600W pulse handling |
Compared with SMAJ6.5A-Q and 1.5SMC6.5A, the P6SMAJ6.5ADFQ-13 uniquely delivers automotive-grade reliability in the smallest qualified footprint, enabling compact, PPAP-ready designs without sacrificing clamping performance or thermal capability.

FAQ
What is the maximum clamping voltage for P6SMAJ6.5ADFQ-13 at its rated peak pulse current?
The maximum clamping voltage is 11.2V at 53.6A peak pulse current, measured using the standard 10/1000µs double-exponential waveform per IEC 61000-4-5. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Is P6SMAJ6.5ADFQ-13 suitable for bidirectional transient suppression?
No - P6SMAJ6.5ADFQ-13 is a unidirectional TVS diode intended for DC power line protection where polarity is fixed. It conducts only when reverse-biased beyond breakdown; for AC or polarity-reversal scenarios, a bidirectional variant such as P6SMBJ6.5ADFQ-13 must be used instead.
How does the D-FLAT package affect thermal performance compared to SMA or SMB packages?
The D-FLAT package provides lower thermal resistance to ambient (RθJA = 92°C/W on optimized 0.4"×0.5" pad) than standard SMA (≈150°C/W), due to its flat, low-profile construction and direct copper-pad thermal path. This enables higher sustained power dissipation in space-constrained automotive layouts without heatsinking.
What automotive standards does P6SMAJ6.5ADFQ-13 comply with beyond AEC-Q101?
In addition to AEC-Q101 qualification, the device meets ISO 10605 (ESD), ISO 7637-2 (transient pulses), and ISO 16750-2 (electrical loads) requirements when applied per recommended layout guidelines. Its IATF16949 manufacturing certification ensures full PPAP documentation and change control for automotive production releases.
