Product details
Overview
SMCJ16AQ-13-F from Diodes Incorporated is a unidirectional 1,500W surface-mount transient voltage suppressor (TVS) designed for automotive power-line protection. It features a 16V reverse standoff voltage (VRWM), 26.0V maximum clamping voltage at 57.7A peak pulse current, and AEC-Q101 qualification for under-hood engine control units and infotainment power rails.
For engineers reviewing the SMCJ16AQ-13-F datasheet, SMCJ16AQ-13-F pinout, SMCJ16AQ-13-F application, or SMCJ16AQ-13-F equivalent, this device is selected for ISO7637-2 Pulse 1/2a/3a/3b surge suppression and ISO10605 ESD protection in 12V/24V automotive systems where fast response (<1 ns), low clamping ratio (1.625), and IATF 16949-manufactured reliability are required.
Technical Context
This TVS diode operates as a shunt-clamping protector: during transients exceeding VRWM = 16V, it avalanches to clamp voltage at ≤26.0V within nanoseconds. Its glass-passivated junction ensures stable breakdown behavior across -55°C to +150°C operating range and supports repetitive surge handling per ISO7637-2 test profiles.
Designed specifically for automotive environments, it meets stringent requirements including 30kV air/contact ESD (ISO10605), -100V Pulse 1, +50V Pulse 2a, -150V Pulse 3a, and +100V Pulse 3b waveforms. The SMC package provides thermal robustness with 5.0W steady-state dissipation at TL = +75°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10×1000μs surges up to 57.7A without failure |
| Reverse Standoff Voltage | 16.0V - blocks normal 12V/24V system operation while remaining inactive |
| Max Clamping Voltage | 26.0V @ IPP = 57.7A - limits downstream IC voltage stress below 28V absolute max |
| Breakdown Voltage | 17.8–19.7V @ IT = 1.0mA - ensures reliable turn-on margin above VRWM |
| Leakage Current | ≤5.0μA @ VRWM - negligible standby power loss in always-on vehicle modules |
| Operating Temp Range | -55°C to +150°C - qualified for engine bay, transmission, and ADAS sensor locations |

|---|---|
Use Scenario: 12V battery feed to microcontroller and sensor power supplies in gasoline/diesel ECUs exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Shunt TVS placed between VBAT and GND upstream of DC-DC converter input. Use Value: Clamps ISO7637-2 Pulse 1 (-100V) to ≤26V, preventing latch-up or gate oxide rupture in 3.3V/5V regulators and MCUs. |
Use Scenario: 12V supply line to head unit mainboard, subject to ignition cycling, jump-start spikes, and ESD from USB/HDMI ports. IC Role / Device Role / Timing Role: Primary surge suppressor on main power entry before fuse and filtering stage. Use Value: Absorbs 30kV contact discharge (ISO10605) and Pulse 3b (+100V) without degradation, preserving display driver and audio codec functionality. |

IC Role / Device Role / Timing Role: First-line defense on power entry before buck converter and image sensor bias circuitry. Use Value: Withstands -55°C to +150°C ambient and clamps Pulse 3a (-150V) to safe levels, ensuring continuous video stream during cold cranking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC16-015 | Same VRWM (16V) but lower PPK = 600W; SOD-123FL package, lower IFSM = 60A | Limited to low-energy surges (e.g., ESD-only); unsuitable for ISO7637-2 Pulse 1 or load dump | Select only for space-constrained non-critical 12V nodes where full 1500W immunity is not required |
| SMCJ16A-Q | Identical electrical specs but non-tape-and-reel packaging (bulk); same AEC-Q101 grade | No functional difference; differs only in logistics-requires manual placement or different feeder setup | Choose when prototyping or low-volume assembly avoids tape-and-reel handling infrastructure |
Compared with SAC16-015, SMCJ16AQ-13-F delivers 2.5× higher surge energy handling and automotive-grade thermal robustness; versus SMCJ16A-Q, it offers optimized logistics for high-volume SMT production with 3000-piece reel packaging and automated placement compatibility.

FAQ
What is the clamping voltage of SMCJ16AQ-13-F at its rated peak pulse current?
The maximum clamping voltage VC is 26.0V measured at IPP = 57.7A using the standardized 10×1000μs waveform per REA and IEC 61000-4-5. This value is guaranteed across the full operating temperature range and represents worst-case voltage seen by downstream circuitry during surge events.
Is SMCJ16AQ-13-F suitable for bidirectional signal line protection?
No - SMCJ16AQ-13-F is unidirectional, indicated by the absence of "C" in its part number. It conducts only during negative transients on the cathode side. For bidirectional protection (e.g., data lines), use SMCJ16CAQ-13-F, which has symmetrical clamping for both polarities.
How does the SMC package affect thermal performance in automotive PCB layouts?
The SMC (DO-214AB) package provides 5.0W steady-state power dissipation at TL = +75°C, requiring minimum 25 mm² copper pour on both sides connected to anode/cathode pads. Thermal resistance from junction-to-lead is 10°C/W, enabling reliable operation in under-hood ambient up to +125°C with proper board-level heatsinking.
Does SMCJ16AQ-13-F require derating at elevated ambient temperatures?
Yes - peak pulse power must be derated linearly above +25°C per Figure 1 in DS40741 Rev. 8-2: at +85°C ambient, PPK is reduced to ~85% of 1500W (≈1275W). Derating applies to both power and peak current; full 1500W rating is valid only at TA ≤ +25°C with terminals held at ambient.
