Product details
Overview
SMAJ16CAQ-13-F from Diodes Incorporated is a bi-directional 400W automotive transient voltage suppressor (TVS) diode with 16V reverse standoff voltage, 26.0V max clamping voltage at 15.3A peak pulse current, and AEC-Q101 qualification for under-hood power line protection in ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD environments.
For engineers reviewing the SMAJ16CAQ-13-F datasheet, SMAJ16CAQ-13-F pinout, SMAJ16CAQ-13-F application, or SMAJ16CAQ-13-F equivalent, key selection criteria include clamping voltage margin vs. system rail, bidirectional surge handling for AC-coupled or floating lines, AEC-Q101 compliance evidence, and SMA package thermal derating above +25°C ambient.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, clamping transients up to 400W (10×1000μs waveform) with <0.5μA leakage at 16V VRWM and 26.0V VC at IPP = 15.3A. It meets ISO10605 ±30kV air/contact discharge and ISO7637-2 Pulse 1 (−100V), Pulse 2a (+50V), Pulse 3a (−150V), Pulse 3b (+100V).
Constructed with glass-passivated die in an SMA package, it delivers 40A IFSM (8.3ms half-sine), −55°C to +175°C operating junction temperature, and RoHS-compliant, halogen-free "Green" construction per Diodes' definitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400W - sustains single 10×1000μs surges without failure; critical for ISO7637-2 Pulse 3a/3b immunity |
| Reverse Standoff Voltage | 16V - maximum continuous DC or RMS voltage before significant leakage; sets minimum system rail margin |
| Max Clamping Voltage | 26.0V @ 15.3A - peak voltage seen by protected IC during worst-case surge; defines downstream overvoltage stress |
| Breakdown Voltage | 17.8–19.7V @ 1.0mA - sharp avalanche onset ensures predictable turn-on; tight 10% tolerance aids design margining |
| Leakage Current | <0.5μA @ 16V - negligible standby power loss; essential for always-on automotive modules |
| AEC-Q101 Qualified | Yes - validated for automotive under-hood use including temperature cycling, HTRB, and ESD stress per AEC standard |
Pinout & Package
Package: SMA (Surface Mount Assembly), molded plastic UL 94V-0, 0.064g mass, moisture sensitivity level 1 (J-STD-020), matte tin-plated terminals solderable per MIL-STD-202 Method 208. Bi-directional device has no polarity indicator.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bi-directional surge path | No polarity marking; either terminal serves as input/output for transient energy absorption in both directions |
Key Features
| Feature | Design Value |
|---|---|
| 400W peak pulse power | Enables robust protection against high-energy ISO7637-2 Pulse 3a (−150V) on 12V battery lines without derating |
| Glass-passivated die | Ensures stable breakdown characteristics and long-term reliability under thermal cycling and humidity exposure |
| AEC-Q101 qualification & PPAP capability | Validates suitability for production automotive ECUs requiring change control and IATF 16949 traceability |
| Bi-directional architecture | Protects AC-coupled signal lines (e.g., CAN, LIN) or floating power domains where polarity reversal occurs |
Applications
| Body Control Module (BCM) Power Input | CAN Transceiver Protection |
|---|---|
Use Scenario: 12V supply line to BCM exposed to load dump and alternator transients per ISO7637-2 Pulse 2a (+50V) and Pulse 3b (+100V). IC Role / Device Role: Primary clamping device shunting surge current away from LDOs, microcontrollers, and power switches. Use Value: 26.0V clamping ensures downstream 3.3V/5V regulators remain within absolute maximum ratings during worst-case events. |
Use Scenario: CAN_H/CAN_L bus lines subjected to ESD events per ISO10605 ±30kV contact discharge and coupled noise from adjacent high-power circuits. IC Role / Device Role: Bidirectional transient clamp placed differential-mode across CAN pair to limit common-mode overvoltage. Use Value: Symmetric 16V standoff and low capacitance preserve CAN signal integrity while suppressing >25V transients. |
| Automotive Lighting Driver | Infotainment USB Interface |
Use Scenario: LED driver power input in headlamp module experiencing repetitive load dump pulses during engine cranking. IC Role / Device Role: Front-end surge suppression before buck controller and gate drivers. Use Value: 40A IFSM rating supports repeated 8.3ms surges without degradation; −55°C to +175°C TJ range matches under-hood thermal profile. |
Use Scenario: VBUS and D+/D− lines of USB 2.0 port in center console exposed to user-hand ESD and cable coupling. IC Role / Device Role: Low-capacitance bi-directional TVS array (paired devices) protecting USB PHY from ±15kV ESD. Use Value: Sub-1μA leakage at 5V ensures no impact on USB suspend current; fast response preserves data eye diagram. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CA | Same electrical specs but not AEC-Q101 qualified; RoHS-compliant but not PPAP-capable | Restricted to non-automotive industrial or consumer applications lacking automotive change control requirements | Select when cost sensitivity outweighs automotive qualification needs and supply chain traceability is not mandated |
| SMCJ16CAQ-13-F | Same AEC-Q101 qualification but SMC package (higher 1500W PPK, larger footprint, 2.3mm height vs. SMA's 2.3mm width) | Used where higher surge energy (e.g., ISO7637-2 Pulse 1 −100V) demands >400W clamping capacity | Select when system-level testing reveals 400W insufficient and board space allows SMC footprint |
Compared with SMAJ16CAQ-13-F, SMAJ16CA lacks automotive qualification documentation and lifecycle controls, while SMCJ16CAQ-13-F trades compact SMA size for higher surge capacity-making SMAJ16CAQ-13-F optimal for space-constrained AEC-Q101 designs needing precise 400W protection.

FAQ
What does the 'C' in SMAJ16CAQ-13-F signify?
The 'C' suffix denotes bi-directional configuration, meaning the device provides symmetrical clamping for both positive and negative transients without polarity dependence. This differs from uni-directional versions (e.g., SMAJ16AQ-13-F) that require correct anode/cathode orientation and only clamp one polarity. Bi-directional operation is essential for AC-coupled buses like CAN or LIN.
How does SMAJ16CAQ-13-F perform under elevated ambient temperatures?
Its peak pulse power derates linearly above +25°C ambient: at +85°C TA, PPK drops to ~280W (70% of rated 400W); at +125°C, it falls to ~160W (40%). This is defined in Figure 1 of DS40739 Rev. 17-2. Designers must verify clamping voltage remains below protected IC limits under worst-case thermal conditions.
Is SMAJ16CAQ-13-F compatible with lead-free reflow processes?
Yes-it features matte tin plating compliant with Pb-free soldering per J-STD-020 Level 1 moisture sensitivity, supporting peak reflow temperatures up to 260°C. The SMA package's thermal mass and UL 94V-0 molding compound ensure reliability through standard lead-free profiles without delamination or voiding.
What is the significance of the 'AQ' suffix in the part number?
The 'AQ' suffix indicates AEC-Q101 qualification and PPAP capability, confirming the device underwent stress testing per automotive reliability standards (including HTGB, HTRB, TCT, and ESD) and is manufactured in IATF 16949-certified facilities with full change control and lot traceability-required for Tier 1 automotive production.
