Product details
Overview
SMCJ64AQ-13-F from Diodes Incorporated is a unidirectional 1,500W automotive transient voltage suppressor (TVS) diode with 64V reverse standoff voltage, 103V max clamping voltage at 14.6A peak pulse current, and AEC-Q101 qualification for under-hood power line protection in ISO7637-2 Pulse 1/2a/3a/3b-compliant systems.
For engineers reviewing the SMCJ64AQ-13-F datasheet, SMCJ64AQ-13-F pinout, SMCJ64AQ-13-F application, or SMCJ64AQ-13-F equivalent, key selection criteria include clamping performance under 10×1000μs surge, bidirectional/unidirectional configuration, AEC-Q101 qualification status, and SMC package thermal derating above +25°C ambient.
Technical Context
This TVS diode operates as a shunt-clamping device during transients, responding in <1 ps to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown behavior across -55°C to +150°C operating temperature range.
Designed specifically for automotive 12V/24V power networks, it meets ISO10605 ESD immunity (30kV air/contact discharge) and withstands ISO7637-2 Pulse 1 (-100V), Pulse 2a (+50V), Pulse 3a (-150V), and Pulse 3b (+100V) waveforms without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10×1000μs surges up to 14.6A without failure |
| Reverse Standoff Voltage | 64V - blocks normal system voltage while remaining inactive below clamp threshold |
| Max Clamping Voltage | 103V @ IPP = 14.6A - limits downstream voltage stress during worst-case ISO7637-2 Pulse 1 |
| Breakdown Voltage | 71.1–78.6V @ IT = 1mA - defines precise conduction onset for predictable clamping margin |
| Leakage Current | ≤5μA @ VRWM = 64V - minimizes quiescent power loss in always-on vehicle modules |
| Operating Temperature | -55°C to +150°C - supports engine bay placement with full electrical performance retention |
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 solderability requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge return path | Connected to ground or low-impedance chassis reference for effective clamping |
| Cathode | Protected line connection | Placed directly on power rail (e.g., battery feed) to intercept incoming transients |
Key Features
| Feature | Design Value |
|---|---|
| 1,500W peak pulse rating | Enables robust protection against high-energy load dump and alternator switching events |
| AEC-Q101 qualified | Validated for automotive use with PPAP capability and IATF 16949 manufacturing control |
| Glass passivated die | Ensures long-term reliability and stable VBR drift over temperature and lifetime |
| Fast response time | <1 ps reaction enables clamping before sensitive ICs experience overvoltage damage |
| RoHS 3 & "Green" compliant | Contains <900ppm Br, <900ppm Cl (<1500ppm total Br+Cl), <1000ppm Sb - meets global environmental mandates |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC50-64A | Lower 500W rating; 100V clamping at 5A; same SMC package | Not suitable for ISO7637-2 Pulse 1 (-100V); limited to lower-energy ESD-only zones | Select only for cost-sensitive non-critical subsystems with verified lower surge exposure |
| SMCJ64A-Q | Identical electrical specs; different marking code and traceability documentation | Same AEC-Q101 qualification but lacks explicit PPAP capability statement in datasheet | Acceptable where full PPAP submission is not required by Tier-1 customer |
Compared with SAC50-64A and SMCJ64A-Q, SMCJ64AQ-13-F provides guaranteed PPAP support, tighter clamping margin (103V vs ≥105V), and documented compliance with all four ISO7637-2 pulses - critical for safety-critical power domains.

FAQ
What is the maximum clamping voltage of SMCJ64AQ-13-F at its rated peak pulse current?
The maximum clamping voltage is 103V when subjected to a 10×1000μs waveform at 14.6A peak pulse current (IPP), measured per REA-defined test conditions. This value is guaranteed across the full operating temperature range and forms the basis for downstream circuit overvoltage design margins.
Is SMCJ64AQ-13-F bidirectional or unidirectional?
SMCJ64AQ-13-F is unidirectional, indicated by the absence of the "C" suffix in its part number. It features a cathode band marking and conducts only during reverse-biased transients, making it suitable for DC power rail protection where polarity is fixed.
Does this TVS diode meet AEC-Q101 requirements for automotive use?
Yes - SMCJ64AQ-13-F is fully AEC-Q101 qualified, manufactured in IATF 16949-certified facilities, and PPAP-capable. Its qualification covers temperature cycling, humidity testing, mechanical shock, and surge endurance per the standard's stress test conditions.
What is the thermal derating behavior above +25°C ambient?
Peak pulse power derates linearly from 100% at +25°C to approximately 50% at +100°C ambient, per Figure 1 in DS40741 Rev. 8-2. Steady-state power dissipation is limited to 5.0W at TL = +75°C, with derating to zero at +150°C per Figure 6.
