Product details
Overview
3.0SMCJ75AQ-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode with 75V reverse standoff voltage, 83.3V minimum breakdown voltage at 1.0mA test current, and 121V maximum clamping voltage at 24.8A peak pulse current. It provides IEC-61000-4-2 ESD protection (30kV air/30kV contact) and is qualified to AEC-Q101 for automotive power rail surge suppression.
For engineers reviewing the 3.0SMCJ75AQ-13 datasheet, 3.0SMCJ75AQ-13 pinout, 3.0SMCJ75AQ-13 application, or 3.0SMCJ75AQ-13 equivalent, this device is selected for high-energy transient suppression in 12V/24V automotive subsystems, industrial DC power inputs, and PoE-powered equipment where low clamping voltage and robust 3000W peak power handling are critical.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 75V standoff rating. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<5µA at VRWM), while the SMC package enables high thermal dissipation under repetitive surge conditions.
The device complies with AEC-Q101 stress testing for automotive use and meets JEDEC reliability standards. Its 10×1000µs waveform clamping performance (121V @ 24.8A) and 8.3ms half-sine surge rating (300A) support protection of downstream DC-DC converters, CAN transceivers, and microcontroller power rails against load dump and ISO 7637-2 pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single high-energy transients without failure, e.g., automotive load dump events |
| Reverse Standoff Voltage | 75V - blocks normal operating voltage up to 75V DC before clamping activates |
| Breakdown Voltage | 83.3–92.1V @ 1.0mA - defines precise avalanche onset threshold for predictable clamping start |
| Clamping Voltage | 121V @ 24.8A - limits voltage seen by protected ICs during worst-case 10×1000µs surge |
| Leakage Current | <5µA @ 75V - negligible standby power loss and no interference with upstream regulators |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects against human-handling electrostatic discharge |
| Operating Temp | −55°C to +150°C - supports under-hood automotive placement and industrial ambient extremes |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with matte tin-plated leads; UL 94V-0 rated; 0.21g weight; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground during overvoltage event |
| Anode | Reference/ground return | Connected to system ground plane; completes clamping path with minimal inductance |
Key Features
| Feature | Design Value |
|---|---|

| Glass-passivated die | Ensures consistent breakdown voltage tolerance and long-term stability under thermal cycling |
| Low clamping ratio (VC/VRWM = 1.61) | Minimizes overvoltage stress on downstream 100V-rated MOSFETs and LDOs |
| RoHS-compliant & halogen-free | Meets automotive OEM environmental requirements (Br+Cl <1500ppm, Sb <1000ppm) |
Applications
| Automotive Body Control Module | Industrial 24V PLC Input |
|---|---|
Use Scenario: Protecting LIN bus transceivers and microcontroller I/O from battery line transients during jump-start or alternator load dump. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VBAT and GND, clamping within 1ns to limit voltage to ≤121V. Use Value: Prevents latch-up or permanent damage to 5V/3.3V logic supplies fed from buck converters tied to the 12V rail. | Use Scenario: Safeguarding digital input terminals of programmable logic controllers exposed to inductive kickback from solenoid valves. IC Role / Device Role / Timing Role: Primary surge shunt on 24V DC input, absorbing 3000W pulses without degradation across 100,000+ cycles. Use Value: Eliminates need for external RC snubbers and extends mean time between failures (MTBF) of field I/O circuitry. |
| PoE-Powered Surveillance Camera | EV Onboard Charger Auxiliary Supply |
Use Scenario: Suppressing Ethernet cable-induced surges (IEC 61000-4-5) entering via 48V PoE power pair before DC-DC conversion. IC Role / Device Role / Timing Role: First-line transient clamp on PoE input rail, activated before internal protection diodes of PMICs. Use Value: Maintains IEEE 802.3af/at compliance while reducing BOM count versus multi-stage TVS+MOV solutions. | Use Scenario: Clamping voltage spikes on 12V auxiliary supply derived from high-voltage battery during regenerative braking transitions. IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional TVS (used with polarity-aware layout) guarding MCU and gate driver power rails. Use Value: Withstands repeated 100V/10ms surges per ISO 16750-2 Pulse 5a, ensuring functional safety integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | 600W peak power, same 75V VRWM, SMC → SMB package (smaller footprint, lower thermal mass) | Limited to lower-energy surges (e.g., ESD-only); unsuitable for load dump or ISO 7637-2 Pulse 5 | Select only for space-constrained consumer electronics with <100W surge exposure |
| 1.5SMC75A | 1500W peak power, identical VRWM/clamp specs, same SMC package but lower PPK rating | Requires derating above 85°C ambient; fails under full 3000W single-pulse stress | Acceptable for cost-sensitive industrial designs with verified worst-case surge energy <1500W |
Compared with SMBJ75A and 1.5SMC75A, the 3.0SMCJ75AQ-13 delivers double the surge energy margin of the SMB variant and twice the peak power headroom of the 1.5kW variant-critical for AEC-Q101-compliant automotive modules where single-event robustness is non-negotiable.

FAQ
What does the 'Q' suffix in 3.0SMCJ75AQ-13 signify?
The 'Q' suffix indicates AEC-Q101 qualification, confirming the device has passed stress tests for automotive applications-including temperature cycling, highly accelerated life testing (HALT), and ESD robustness. It is manufactured in IATF 16949-certified facilities and supports PPAP documentation for Tier 1 suppliers.
Can 3.0SMCJ75AQ-13 be used in bidirectional configurations?
No-it is a unidirectional TVS diode with a cathode band marking. For bidirectional protection, Diodes offers the 3.0SMCJ75CA-13 variant. Using the 'Q' version in reverse-biased mode risks premature failure due to lack of symmetrical avalanche structure.
How does its clamping voltage compare to competing 75V TVS diodes?
At 24.8A IPP, its 121V clamping voltage is 3–5% lower than standard industry equivalents (e.g., STMicro's SMAJ75A: 125V). This tighter VC/VRWM ratio (1.61×) reduces overvoltage stress on 100V-rated downstream FETs and improves system-level surge margin.
Is tape-and-reel packaging compatible with high-speed SMT assembly?
Yes-the 3000-piece tape-and-reel format (EIA-481 compliant) supports automated pick-and-place at rates up to 45,000 CPH. The SMC package's 7.75–8.13mm body length and 2.00–2.50mm lead spacing ensure reliable vision-system recognition and placement accuracy.
