Product details
Overview
SMCJ6.5AQ-13-F from Diodes Incorporated is a unidirectional 1,500W automotive transient voltage suppressor (TVS) diode in SMC package, with 6.5V reverse standoff voltage, 11.2V max clamping voltage at 133.9A peak pulse current, and AEC-Q101 qualification for ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD protection in vehicle power line and signal interface circuits.
For engineers reviewing the SMCJ6.5AQ-13-F datasheet, SMCJ6.5AQ-13-F pinout, SMCJ6.5AQ-13-F application, or SMCJ6.5AQ-13-F equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, peak surge current capability under ISO7637-2 Pulse 3b (+100V), thermal derating above +25°C ambient, and unidirectional polarity alignment with DC-biased automotive rails.
Technical Context
This TVS operates as a voltage-clamping overvoltage protection device on automotive 12V systems, triggered when transient voltage exceeds 7.22V (min breakdown) and clamping to ≤11.2V within nanoseconds. Its glass-passivated junction ensures stable leakage (<500µA at 6.5V) and repeatable avalanche behavior across -55°C to +150°C junction temperature range.
Designed for single-polarity DC lines, it delivers 1,500W peak pulse power per 10×1000µs waveform, with 200A non-repetitive forward surge rating and 5W steady-state dissipation at TL = +75°C. Compliance with IATF 16949 manufacturing and PPAP capability supports Tier-1 automotive supply chain requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains 10×1000µs transients without failure in automotive load-dump or inductive switching events |
| Reverse Standoff Voltage | 6.5V - maximum continuous DC voltage before significant leakage; sets minimum system operating margin |
| Clamping Voltage @ IPP | 11.2V @ 133.9A - limits downstream IC stress during ISO7637-2 Pulse 3b (+100V) surges |
| Breakdown Voltage | 7.22–7.98V @ 10mA - defines precise avalanche initiation threshold for predictable protection timing |
| Leakage Current | ≤500µA @ 6.5V - ensures negligible standby power loss and no false triggering on nominal 12V rail |
| Operating Temperature | -55°C to +150°C - supports engine bay, transmission control, and ADAS module mounting locations |
Pinout & Package
Package: SMC (DO-214AB), surface-mount molded plastic body with UL 94V-0 flammability rating, cathode band polarity indicator, and matte tin lead finish compliant with MIL-STD-202 soldering standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | DC return path for clamped surge current | Connected to ground or low-side reference; completes avalanche conduction loop during overvoltage |
| Cathode | Protected line input terminal | Connected to 12V rail or signal line; voltage sensed here determines clamping activation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use with temperature cycling, HTRB, and ESD testing per JESD22-A114 |
| Glass-passivated die | Stable electrical parameters and reduced parameter drift over lifetime in harsh under-hood environments |
| 1,500W peak pulse rating | Handles worst-case ISO7637-2 Pulse 1 (-100V) and Pulse 3a (-150V) without degradation |
| Fast response time | Sub-nanosecond turn-on enables protection of fast logic and CAN transceivers against ESD transients |
| RoHS 3 & "Green" compliant | Halogen-free (<900ppm Br/Cl, <1000ppm Sb) and lead-free construction for global automotive compliance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC5.0A-13-F | Lower 500W peak power; 5V standoff; 9.2V clamping at 54.3A | Suitable only for low-energy signals (e.g., CAN, LIN), not 12V power rails | Select when protecting sub-100mA interfaces where 1,500W rating is unnecessary and board space is constrained |
| SMBJ6.5A-13-F | Same 6.5V standoff but SMB package; 600W peak power; 11.2V clamping at 53.6A | Lower surge capacity; limited to non-critical 12V nodes with lower ISO7637-2 exposure | Choose for cost-sensitive interior modules where full 1,500W rating is not mandated by OEM spec |
Compared with SAC5.0A-13-F and SMBJ6.5A-13-F, SMCJ6.5AQ-13-F provides 2.5× higher peak power and 2.5× higher surge current-critical for front-end 12V protection in powertrain and ADAS systems requiring full ISO7637-2 compliance.

FAQ
What is the difference between SMCJ6.5AQ-13-F and SMCJ6.5A-13-F?
The "Q" suffix denotes AEC-Q101 qualification and PPAP capability, including extended reliability testing (HTGB, TCT, H3TRB), IATF 16949 manufacturing, and automotive-specific change control. The non-Q version lacks formal automotive qualification and is intended for industrial or consumer use only.
Can SMCJ6.5AQ-13-F be used on a 24V automotive system?
No-it is rated for 6.5V standoff and designed for 12V nominal systems. For 24V applications, use SMCJ24AQ-13-F (24V standoff, 38.9V clamping). Using SMCJ6.5AQ-13-F on 24V would cause continuous avalanche conduction, thermal runaway, and catastrophic failure.
Is the SMCJ6.5AQ-13-F bidirectional?
No-it is unidirectional, indicated by the absence of "C" in the part number. Bidirectional versions include "C" (e.g., SMCJ6.5CAQ-13-F) and lack a cathode band. Unidirectional operation ensures optimal clamping on DC-biased lines like 12V power rails.
What is the thermal resistance from junction to lead (RθJL) for SMCJ6.5AQ-13-F?
RθJL is 15°C/W, derived from PM(AV) = 5.0W at TL = +75°C and maximum TJ = +150°C (ΔT = 75°C). This value assumes proper PCB copper pour (≥100mm² per pad) and is critical for calculating safe surge repetition rates in thermally constrained layouts.
