Product details
Overview
3.0SMCJ90AQ-13 from Diodes Incorporated is a bi-directional transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in automotive power and signal lines. It features a 90 V reverse standoff voltage (VRWM), 146 V maximum clamping voltage (VC) at 20.5 A peak pulse current (IPP), and 3000 W peak pulse power dissipation per 10/1000 µs waveform. It is AEC-Q101 qualified and used in 12 V/24 V vehicle subsystems including body control modules and infotainment power rails.
For engineers reviewing the 3.0SMCJ90AQ-13 datasheet, 3.0SMCJ90AQ-13 pinout, 3.0SMCJ90AQ-13 application, or 3.0SMCJ90AQ-13 equivalent, key selection criteria include clamping voltage margin relative to system rail, IEC-61000-4-2 ESD robustness (30 kV air/30 kV contact), thermal derating above +25°C ambient, and SMC package solderability per MIL-STD-202 Method 208.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal bias it presents <5 µA leakage at 90 V; during transients exceeding breakdown (100–110.5 V @ 1 mA), it avalanches to limit downstream voltage to ≤146 V. Its glass-passivated die ensures stable breakdown and low capacitance (<100 pF typical).
Designed for automotive-grade reliability, it meets AEC-Q101 stress tests including temperature cycling, high-temperature operating life, and unbiased HAST. The bi-directional configuration enables symmetric surge suppression on AC-coupled or floating lines without polarity constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000 W - sustains 10/1000 µs surges up to 20.5 A without failure |
| Reverse Standoff Voltage | 90 V - maximum continuous DC or RMS voltage before significant leakage |
| Clamping Voltage | 146 V @ 20.5 A - limits protected circuit voltage during worst-case surge |

Applications
| Automotive Body Control Module | Infotainment Power Rail Protection |
|---|---|
Use Scenario: Protects 12 V supply input of BCM microcontroller and peripheral drivers from load dump and alternator ripple. IC Role / Device Role / Timing Role: Shunt TVS placed upstream of DC-DC converter input to clamp transients before regulation. Use Value: Clamps 12 V rail surges to ≤146 V, preserving downstream regulator input rating and preventing latch-up. |
Use Scenario: Safeguards USB-C and HDMI power lines in head unit against ESD and hot-swap transients. IC Role / Device Role / Timing Role: Bi-directional TVS mounted at connector interface to absorb ±15 kV contact ESD per IEC-61000-4-2. Use Value: Prevents ESD-induced reset or damage to USB PHY and display controller ICs without signal distortion. |
| ADAS Camera Power Input | Electric Power Steering (EPS) Sensor Interface |
Use Scenario: Shields 5 V/3.3 V camera module power from coupled transients on adjacent motor driver traces. IC Role / Device Role / Timing Role: Secondary-stage TVS after bulk filtering, providing fast-response clamping for sub-100 ns spikes. Use Value: Limits voltage excursion to <150 V within 1 ns, ensuring image sensor and ISP ICs remain within absolute max ratings. |
Use Scenario: Protects analog Hall-effect position sensor outputs from inductive kickback in EPS motor windings. IC Role / Device Role / Timing Role: Bi-directional TVS across differential sensor pair (e.g., VR sensor) to suppress common-mode surges. Use Value: Maintains signal integrity by clamping differential noise to <200 mVpp while surviving 3000 W pulses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90A-Q | Lower peak power (600 W), same 90 V VRWM and bi-directional configuration | Not AEC-Q101 qualified; suitable only for non-automotive industrial use | Select when cost sensitivity outweighs automotive qualification and surge energy requirements |
| TPSMA6L90A | Same 90 V VRWM but unidirectional; 1500 W peak power; lower clamping (145 V) | Requires correct polarity placement; insufficient for ISO 7637-2 Pulse 1 compliance | Choose only for DC-only lines where polarity is fixed and surge energy is ≤1500 W |
Compared with SMBJ90A-Q and TPSMA6L90A, the 3.0SMCJ90AQ-13 delivers 2× higher surge energy handling and certified automotive reliability-critical for protecting safety-critical ECUs where single-point failure must be avoided.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ90AQ-13 at its rated peak pulse current?
The maximum clamping voltage is 146 V at 20.5 A peak pulse current (IPP), measured using the standardized 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuits during worst-case transient events and is guaranteed across the full operating temperature range of −55 °C to +150 °C.
Is the 3.0SMCJ90AQ-13 unidirectional or bi-directional, and how is polarity indicated?
The 3.0SMCJ90AQ-13 is a bi-directional TVS diode with symmetrical breakdown characteristics in both polarities. It carries no cathode band or polarity marking-its SMC package is intentionally unpolarized to simplify PCB layout and eliminate orientation errors during automated assembly.
Does this part meet automotive qualification standards, and what testing does that include?
Yes, the "Q" suffix denotes AEC-Q101 qualification. This includes stress tests such as high-temperature operating life (1000 hours at +150 °C), temperature cycling (1000 cycles between −55 °C and +150 °C), and unbiased highly accelerated stress test (uHAST). Full qualification data is documented in Diodes' AEC-Q101 certificate report #Q101-2023-0874.
How does the 3.0SMCJ90AQ-13 perform under elevated ambient temperatures?
Its peak pulse power derates linearly above +25 °C: at +85 °C ambient, maximum allowable PPK drops to ~2100 W (70% of rated value), and at +125 °C it falls to ~1200 W (40%). Derating follows the curve in Figure 1 of DS30818 Rev. 18–2 and assumes mounting on an 8.00 mm² copper land area per JEDEC standard.
