Product details
Overview
3.0SMCJ170AQ-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) with 170V reverse standoff voltage, 275V max clamping voltage at 10.9A peak pulse current, and IEC-61000-4-2 ESD rating of 30kV (air/contact). It protects automotive power rails and industrial DC inputs against lightning-induced surges and inductive switching transients.
For engineers reviewing the 3.0SMCJ170AQ-13 datasheet, 3.0SMCJ170AQ-13 pinout, 3.0SMCJ170AQ-13 application, or 3.0SMCJ170AQ-13 equivalent, key selection criteria include clamping voltage margin relative to system rail, peak pulse current handling under 10/1000μs waveform, thermal derating above +25°C ambient, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode uses glass-passivated silicon junction construction to achieve low dynamic impedance and fast response (<1ps) to transient events. Its unidirectional configuration provides asymmetric clamping-low forward voltage during normal operation and high reverse breakdown at 189–208.9V-with cathode band polarity marking.
Designed for placement across DC power lines, it operates within -55°C to +150°C junction temperature range and complies with JEDEC high-reliability standards. The device sustains 3000W non-repetitive peak pulse power per 10×1000μs waveform and supports up to 300A surge current under 8.3ms half-sine conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - Sustains single-event surges up to 3kW without failure under 10×1000μs waveform |
| Reverse Standoff Voltage (VRWM) | 170V - Maximum continuous DC or RMS voltage before significant leakage; sets minimum system rail margin |
| Breakdown Voltage (VBR) | 189–208.9V @ 1mA - Confirmed avalanche onset range; ensures reliable triggering above VRWM |
| Max Clamping Voltage (VC) | 275V @ 10.9A - Upper voltage limit seen by protected circuit during worst-case 10×1000μs transient |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - Withstands direct electrostatic discharge without degradation |
| Operating Temperature | -55°C to +150°C - Validated for under-hood automotive and industrial environments with wide thermal cycling |
| Package | SMC (DO-214AB) - Surface-mount outline with 6.9mm pad width and 9.4mm overall length for high-current PCB routing |
Pinout & Package
Package: SMC (DO-214AB), molded plastic body with matte tin-plated leads, UL 94V-0 flammability rating, and 0.21g mass. Cathode band denotes terminal polarity for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or return path; carries full surge current during clamping event |
| Cathode | High-side protection node | Connected to protected line (e.g., 12V/24V rail); blocks reverse leakage below VRWM, avalanches above VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Enables stable breakdown characteristics and long-term reliability under repeated surge stress |
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS power supplies |
| Lead-free & halogen-free | Complies with RoHS 3 (2015/863/EU) and Diodes' "Green" definition (<900ppm Br/Cl, <1000ppm Sb) |
| Moisture sensitivity Level 1 | No baking required prior to reflow; compatible with standard SMT assembly processes |
Applications
| Automotive Power Rail Protection | Industrial DC Input Surge Suppression |
|---|---|
|
Use Scenario: 12V/24V battery-fed ECUs exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp transients exceeding 170V standoff. Use Value: Limits clamped voltage to 275V, maintaining >20V margin below typical 300V-rated downstream capacitors and regulators. |
Use Scenario: 48V telecom rectifier outputs subject to lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary overvoltage protector on DC bus before DC-DC converters and backplane interfaces. Use Value: Absorbs 3000W peak energy in <1μs, preventing latch-up or catastrophic failure in upstream MOSFETs and controllers. |
| Motor Drive Inverter DC Link | EV Onboard Charger Input Stage |
|
Use Scenario: High-current DC link between rectifier and IGBT module in HVAC compressors or industrial pumps. IC Role / Device Role / Timing Role: Fast-clamping TVS parallel to bulk capacitor to suppress commutation spikes and regenerative energy transients. Use Value: Responds in <1ps to dV/dt >1000V/μs, limiting voltage overshoot to ≤275V and protecting 600V-class IGBT gate drivers. |
Use Scenario: AC/DC front-end of 6.6kW OBC handling grid surges and EVSE interconnection transients. IC Role / Device Role / Timing Role: Secondary protection after MOVs, providing precise clamping and low-leakage hold-off for 400V+ DC bus. Use Value: Maintains <5μA leakage at 170V, minimizing standby loss while delivering 10.9A IPP into 10×1000μs test waveform. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ170A | 2000W PPK, same VRWM/VBR/VC but lower surge rating; SMB package (smaller footprint, lower thermal mass) | Acceptable for lower-energy transients (e.g., I/O lines), not suitable for 12V/24V power rail load dump | Select when board space is constrained and peak surge energy remains ≤2kW |
| SMCJ170A | Identical electrical specs and SMC package, but lacks AEC-Q101 qualification and automotive change control | Approved for commercial/industrial use only; excluded from PPAP-managed automotive BOMs | Choose for cost-sensitive non-automotive designs where automotive qualification is unnecessary |
Compared with SMBJ170A and SMCJ170A, the 3.0SMCJ170AQ-13 delivers higher surge robustness (3000W vs. 2000W/3000W), guaranteed automotive qualification (Q-suffix), and traceable IATF 16949 manufacturing-making it the sole option for safety-critical vehicle subsystems requiring validated lifecycle control.

FAQ
What does the 'Q' suffix indicate in 3.0SMCJ170AQ-13?
The 'Q' suffix confirms AEC-Q101 qualification, meaning the device has passed stress tests for automotive-grade reliability-including temperature cycling, humidity bias HAST, and accelerated life testing. It also signifies production in IATF 16949-certified facilities with PPAP documentation support and controlled change management for automotive BOMs.
Can 3.0SMCJ170AQ-13 be used in bidirectional configurations?
No-this part is unidirectional, indicated by the cathode band marking and its electrical specification table entry under "Uni-" column. Bidirectional variants (e.g., 3.0SMCJ170CA-13) lack polarity marking and exhibit symmetrical clamping in both directions, which this Q-suffix part does not support.
How does the 10×1000μs clamping voltage relate to real-world surge events?
The 275V clamping voltage is measured under standardized 10×1000μs waveform (10μs rise, 1000μs decay), matching common lightning surge and inductive switch-off profiles. Real-world events like ISO 7637-2 Pulse 5a (load dump) have longer duration but lower peak current-so actual clamped voltage remains at or below 275V due to thermal derating and device dynamics.
Is moisture sensitivity level (MSL) a concern during reflow soldering?
No-3.0SMCJ170AQ-13 is rated MSL Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH and subjected to standard lead-free reflow profiles (peak 260°C) without preconditioning or baking. This simplifies SMT line integration and eliminates moisture-related popcorning risk.
