Product details
Overview
SMAJ6.0A-13-F from Diodes Incorporated is a unidirectional 400W surface-mount transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 6.0V reverse standoff voltage, 10.3V max clamping voltage at 38.8A peak pulse current, and fast response time to ESD and surge events. Used in automotive infotainment power inputs and industrial sensor interface protection.
For engineers reviewing the SMAJ6.0A-13-F datasheet, SMAJ6.0A-13-F pinout, SMAJ6.0A-13-F application, or SMAJ6.0A-13-F equivalent, key selection criteria include clamping voltage margin relative to protected IC VMAX, IPP capability under 8.3ms surge waveforms, thermal derating above +25°C ambient, and compatibility with SMA package reflow profiles.
Technical Context
This TVS operates as a silicon avalanche diode that remains high-impedance below 6.0V VRWM and clamps sharply above breakdown (6.67–7.37V at 10mA). Its glass-passivated die construction ensures stable leakage (<800µA at VRWM) and repeatable clamping performance across temperature (-55°C to +150°C).
The device handles 40A non-repetitive forward surge current (8.3ms half-sine) and dissipates 1.0W steady-state power at TL = +75°C. Its unidirectional polarity-marked by a cathode band-enables asymmetric protection of positive-rail circuits without reverse conduction during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400W - sustains single 8.3ms surges per REA 10×1000 waveform without failure |
| Reverse Standoff Voltage | 6.0V - maximum continuous DC or RMS voltage before significant leakage begins |
| Clamping Voltage | 10.3V @ 38.8A - limits transient voltage seen by downstream ICs during surge events |
| Breakdown Voltage | 6.67–7.37V @ 10mA - defines precise avalanche onset range for predictable triggering |
| Leakage Current | <800µA @ 6.0V - ensures minimal power loss and no interference in low-current standby modes |
| Package | SMA (DO-214AC) - industry-standard surface-mount outline with 4.0–4.6mm body width and 2.29–2.92mm height |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with UL 94V-0 flammability rating, cathode band marking on unidirectional devices. Moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; completes clamping loop during positive transients |
| Cathode | High-side connection point | Connected to protected line; conducts avalanche current when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| 400W peak pulse power | Enables robust protection against IEC 61000-4-5 Level 3 (1kV/2Ω) surges on 12V automotive supplies |
| Glass-passivated die | Ensures long-term parameter stability and resistance to humidity-induced degradation in harsh environments |
| Lead-free, RoHS-compliant plating | Meets IPC-J-STD-020 reflow requirements and eliminates Pb-based solder compatibility concerns |
| Fast response time | Sub-nanosecond turn-on enables suppression before sensitive logic or analog circuitry is damaged |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input |
|---|---|
Use Scenario: Protecting 12V supply rail of BCM microcontroller from load-dump transients up to 35V. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND to clamp positive surges only. Use Value: Limits rail voltage to ≤10.3V during 38.8A 8.3ms pulses, preserving MCU reset threshold integrity. |
Use Scenario: Safeguarding 24V digital input channel against field-wiring induced surges and ESD. IC Role / Device Role / Timing Role: Primary front-end protection before optocoupler or Schmitt trigger input stage. Use Value: Prevents latch-up in input buffer ICs by clamping transients before they exceed absolute maximum ratings. |
| USB-C Power Delivery Port | Smart Meter Communication Interface |
Use Scenario: Secondary overvoltage guard on VBUS line after primary protection, targeting fast ESD events. IC Role / Device Role / Timing Role: Low-capacitance TVS (typ. 350pF at 0V) placed adjacent to USB-C connector. Use Value: Clamps ±15kV contact ESD (IEC 61000-4-2) without distorting 5–20V PD signaling waveforms. |
Use Scenario: Protecting RS-485 transceiver pins in outdoor smart meter installations exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Line-to-ground TVS on A/B differential pair, referenced to local chassis ground. Use Value: Absorbs 400W common-mode surges while maintaining <10.3V differential clamping margin for transceiver survival. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/5A (Vishay) | Same 6.0V VRWM, 10.3V VC, but higher IR (1mA max vs. 800µA) and different marking code | Approved for Vishay-qualified automotive programs; slightly looser leakage spec may affect ultra-low-power sleep modes | Select if sourcing from Vishay-authorized channels or requiring alternate qualification documentation |
| 1.5SMC6.0A (ON Semiconductor) | Higher PM(AV) (1.5W vs. 1.0W), same 400W PPK, but larger SMC (DO-214AB) package (7.1mm width) | Requires PCB redesign due to 2.5× footprint increase; better thermal mass for sustained surge duty cycles | Choose when board layout allows larger package and system requires extended thermal endurance beyond +75°C lead temp |
Compared with SMAJ6.0A-13-F, the Vishay alternative offers identical electrical protection but less stringent leakage control, while the ON Semiconductor part trades compactness for higher steady-state power handling-making the Diodes device optimal for space-constrained, low-leakage 12V rail protection.

FAQ
What is the maximum operating temperature for SMAJ6.0A-13-F?
The SMAJ6.0A-13-F has a junction temperature range of –55°C to +150°C and a storage temperature range of –55°C to +150°C. Its steady-state power dissipation is rated at 1.0W at TL = +75°C, with linear derating to zero at +150°C per Figure 6 in the datasheet.
Is SMAJ6.0A-13-F suitable for bidirectional signal line protection?
No - SMAJ6.0A-13-F is unidirectional and marked with a cathode band. For bidirectional protection (e.g., RS-485, USB D+/D–), use the bidirectional variant SMAJ6.0CA-13-F, which lacks polarity marking and clamps symmetrically for both polarities.
How does the clamping voltage change with increasing peak pulse current?
Clamping voltage increases nonlinearly with current: at 10A IPP it is ~7.5V, rising to 10.3V at rated 38.8A. This behavior follows the device's dynamic IV curve and must be verified using the manufacturer's SPICE model or measured waveforms per REA 10×1000 standard.
Can SMAJ6.0A-13-F replace SMAJ5.0A-13-F in an existing design?
Only if the protected circuit's maximum working voltage is ≥6.0V and clamping margin (10.3V – IC VABS_MAX) remains sufficient. SMAJ5.0A clamps at 9.2V but triggers at lower voltage (5.0V VRWM); substituting SMAJ6.0A raises the trip threshold and may allow damaging overvoltage before clamping begins.
