Product details
Overview
SMCJ13AQ-13-F from Diodes Incorporated is a unidirectional 1,500W automotive transient voltage suppressor (TVS) diode with 13V reverse standoff voltage, 21.5V max clamping voltage at 69.7A peak pulse current, and AEC-Q101 qualification for under-hood power line protection in ISO7637-2 Pulse 1/2a/3a/3b-compliant systems.
For engineers reviewing the SMCJ13AQ-13-F datasheet, SMCJ13AQ-13-F pinout, SMCJ13AQ-13-F application, or SMCJ13AQ-13-F equivalent, key selection criteria include clamping voltage margin relative to system rail, IPP capability under 10/1000μs surge, thermal derating above +25°C, and SMC package solderability per MIL-STD-202.
Technical Context
This TVS operates as a shunt-clamping device triggered by avalanche breakdown when reverse voltage exceeds 14.4V (min VBR)-ensuring fast response (<1 ps) to transients while maintaining <5μA leakage at 13V VRWM. Its glass-passivated die construction ensures stable parametric performance across -55°C to +150°C junction temperature.
Designed for single-line automotive power rail protection, it handles non-repetitive 8.3ms half-sine surges up to 200A IFSM and dissipates 5W steady-state power at TL = +75°C. Clamping behavior follows the standardized 10×1000μs waveform per REA definition, with derating to 50% peak power at +100°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains 10×1000μs surge without failure in automotive load dump scenarios |
| Reverse Standoff Voltage | 13.0V - maximum continuous DC voltage before significant leakage; sets minimum system rail compatibility |
| Clamping Voltage @ IPP | 21.5V @ 69.7A - limits transient voltage seen by downstream ICs during ISO7637-2 Pulse 1 (-100V) |
| Breakdown Voltage | 14.4–15.9V @ 1.0mA - defines precise avalanche onset window for predictable clamping threshold |
| Leakage Current | <5.0μA @ 13.0V - negligible standby power loss and signal integrity impact on 12V systems |
| Operating Temperature | -55°C to +150°C - supports engine compartment placement per AEC-Q101 stress test requirements |
Pinout & Package
Package: SMC (DO-214AB), surface-mount molded plastic body with UL 94V-0 flammability rating, cathode band polarity indicator, and matte tin lead finish solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Banded End) | Anode-to-Cathode Reverse Bias Path | Connected to protected line; conducts avalanche current to ground during overvoltage |
| Anode (Non-Banded End) | Reference / Ground Return | Typically tied to chassis or power ground; completes clamping path for unidirectional operation |
Key Features
| Feature | Design Value |
|---|---|
| 1,500W Peak Pulse Power | Enables robust protection against severe load dump and jump-start transients without thermal runaway |
| AEC-Q101 Qualified | Validated for automotive under-hood use via high-temperature operating life, ESD, and mechanical shock testing |
| Glass Passivated Die | Eliminates moisture-induced parameter drift and improves long-term reliability in humid environments |
| Lead-Free & Halogen-Free | Complies with RoHS 3 and automotive green standards (<900ppm Br/Cl, <1000ppm Sb) |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) CAN Bus Line |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | 600W PPK, same VRWM and VC, SMB package (smaller footprint, lower thermal mass) | Limited to lower-energy transients; unsuitable for full ISO7637-2 Pulse 1 compliance | Select when board space is constrained and surge severity is limited to ISO10605-level ESD only |
| SMCJ13AHE3_A/H | Vishay equivalent with identical 1500W rating, same SMC package, but different marking and traceability documentation | Same functional performance; requires validation of PPAP documentation alignment for Tier 1 automotive programs | Choose for dual-sourcing where Diodes' change control process does not align with program requirements |
Compared with SMBJ13A and SMCJ13AHE3_A/H, SMCJ13AQ-13-F provides guaranteed AEC-Q101 qualification, IATF 16949 manufacturing, and explicit ISO7637-2 Pulse 1/2a/3a/3b compliance-making it the preferred choice for safety-critical power rail protection where full automotive qualification evidence is mandatory.

FAQ
What is the difference between SMCJ13AQ-13-F and SMCJ13A?
The "Q" suffix denotes AEC-Q101 qualification, PPAP capability, and manufacture in IATF 16949-certified facilities-critical for automotive production. Standard SMCJ13A lacks formal automotive qualification documentation and may be produced in non-automotive fabs, limiting its use in Tier 1 supply chains despite identical electrical specs.
Can SMCJ13AQ-13-F be used for bidirectional protection?
No-SMCJ13AQ-13-F is unidirectional. For bidirectional protection (e.g., CAN bus), the part number must include the "C" suffix: SMCJ13CAQ-13-F. The "C" version has symmetrical breakdown in both polarities and no cathode band marking, enabling clamping of both positive and negative transients.
What is the thermal resistance from junction to lead (RθJL) for this device?
RθJL is not specified in DS40741 Rev. 8-2. However, the datasheet confirms 5.0W steady-state power dissipation at TL = +75°C, implying RθJL ≈ 15°C/W based on standard SMC package thermal models. For precise thermal design, users should apply JEDEC JESD51-14 transient dual-interface measurement or reference Diodes' thermal simulation tools.
How does the 10×1000μs waveform affect clamping voltage specification?
The 21.5V clamping voltage is measured exclusively under the 10×1000μs double-exponential surge waveform (per REA definition). This differs from 8.3ms half-sine testing used for IFSM; using the wrong waveform invalidates the VC spec. Designers must ensure test equipment replicates this exact shape to verify compliance.
