Product details
Overview
3.0SMCJ36AQ-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode with 36V reverse standoff voltage, 40.0–44.2V breakdown voltage at 1mA, and 58.1V max clamping voltage at 51.6A peak pulse current. It provides IEC-61000-4-2 ESD protection (30kV air/30kV contact), operates from –55°C to +150°C, and is qualified for automotive applications per AEC-Q101.
For engineers reviewing the 3.0SMCJ36AQ-13 datasheet, 3.0SMCJ36AQ-13 pinout, 3.0SMCJ36AQ-13 application, or 3.0SMCJ36AQ-13 equivalent, this device is selected for high-energy surge suppression in DC power rails, automotive infotainment interfaces, and industrial sensor signal lines where low clamping voltage and fast response (<1ns) are critical for protecting downstream ICs like CAN transceivers and microcontrollers.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for unidirectional clamping in DC-biased circuits. Its 3000W peak pulse power rating is specified under the 10×1000μs waveform, with thermal derating above +25°C per JEDEC-standard curve (Fig. 1). The cathode-band polarity marking ensures correct orientation during PCB layout.
It meets AEC-Q101 stress test requirements including HTGB, HTRB, and temperature cycling, and features RoHS-compliant matte tin-plated leads solderable per MIL-STD-202 Method 208. Moisture sensitivity level is rated at Level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10×1000μs surges up to 51.6A without failure |
| Reverse Standoff Voltage (VRWM) | 36V - maximum continuous DC voltage before leakage exceeds 5µA |
| Breakdown Voltage (VBR) | 40.0–44.2V @ 1mA - precise conduction onset for predictable clamping threshold |
| Max Clamping Voltage (VC) | 58.1V @ 51.6A - limits transient voltage seen by protected ICs to safe levels |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - eliminates need for external ESD diodes in many designs |
| Operating Temperature | –55°C to +150°C - supports under-hood automotive and industrial environments |
Pinout & Package
Package: SMC (DO-214AB), molded plastic body with UL 94V-0 flammability rating; weight ≈ 0.21g; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | DC return path for clamped surge current | Connected to system ground or low-side rail; must handle ≥51.6A transient pulses |
| Cathode | Protected line input (marked with band) | Connected to line being protected (e.g., 36V supply rail); conducts when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Enables stable VBR tolerance and long-term reliability under thermal cycling and humidity stress |
| 3000W peak pulse power | Protects against severe ISO 7637-2 Load Dump (Test Pulse 5a) and lightning-induced surges in 12V/24V systems |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body control, and ADAS modules requiring PPAP documentation |
| Lead-free, halogen-free "Green" construction | Meets EU RoHS 3 (2015/863/EU) and automotive OEM material compliance requirements |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: 12V/24V battery-fed ECUs exposed to load dump and jump-start transients. IC Role / Device Role: Primary overvoltage clamp on main power input before LDOs and microcontrollers. Use Value: Limits voltage to ≤58.1V during 3000W surges, preventing damage to 40V-rated power management ICs. |
Use Scenario: 4–20mA current loop transmitters in factory automation with long cable runs. IC Role / Device Role: Bidirectional surge shunt on analog input/output lines connected to field wiring. Use Value: Clamps induced lightning surges to <60V, preserving accuracy of precision op-amps and ADCs downstream. |
| USB-C Power Delivery Port | Motor Drive Control Signal Line |
Use Scenario: VBUS line in automotive USB-C chargers subject to hot-plug and ESD events. IC Role / Device Role: Unidirectional TVS on 20V-rated PD controller power input. Use Value: Absorbs 30kV contact ESD per IEC-61000-4-2 without latch-up, maintaining PD negotiation integrity. |
Use Scenario: PWM enable/disable signals routed near high-current motor phases. IC Role / Device Role: Low-capacitance transient suppressor on gate driver logic inputs. Use Value: Prevents false triggering of half-bridge drivers during 8.3ms surge events with <1ns response time. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | 600W rating, same VRWM/VBR but lower IPP (25.8A) and higher VC (60.0V) | Not suitable for ISO 7637-2 Pulse 5a; limited to lower-energy surges | Select only if board space constraints prohibit SMC footprint and surge energy is <100mJ |
| SMCJ36A | Same 3000W rating and SMC package, but not AEC-Q101 qualified | Lacks automotive change control, PPAP support, and IATF 16949 traceability | Acceptable for industrial non-automotive use where qualification documentation is not required |
Compared with SMBJ36A and SMCJ36A, the 3.0SMCJ36AQ-13 uniquely combines full AEC-Q101 qualification, 3000W surge capability, and guaranteed low clamping voltage (58.1V), making it the only option for production automotive modules requiring both robustness and audit-ready compliance.

FAQ
What does the 'Q' suffix signify in 3.0SMCJ36AQ-13?
The 'Q' suffix indicates full AEC-Q101 qualification, including stress testing (HTGB, HTRB, temperature cycling), PPAP documentation readiness, and manufacturing in IATF 16949-certified facilities. It is not present on standard industrial-grade variants like SMCJ36A.
Can 3.0SMCJ36AQ-13 be used in bidirectional configurations?
No-it is unidirectional, marked with a cathode band. For bidirectional protection at 36V standoff, Diodes offers the 3.0SMCJ36CA-13 variant, which has symmetrical breakdown in both polarities and no polarity indicator.
What is the recommended PCB pad layout for optimal thermal performance?
Per Diodes' SMC package outline, use 8.00mm² copper land areas (minimum 0.013mm thick) for each terminal to meet the 300A surge current rating and achieve full 3000W pulse power dissipation without thermal runaway.
How does its clamping voltage compare to competing 36V TVS diodes?
At 51.6A IPP, its 58.1V clamping voltage is 3.2% lower than the industry-standard SM5S36A (60.0V), reducing stress on downstream 40V-rated ICs and enabling tighter safety margins in 36V system designs.
