Product details
Overview
MMBZ27VALQ-13-F from Diodes Incorporated is a dual unidirectional TVS diode in common-anode SOT23 package, rated for 40W peak pulse power (1ms), 22.0V minimum breakdown voltage, and 40A peak pulse current. It provides ESD and transient protection for automotive signal lines such as CAN FD, LIN, and sensor interfaces operating up to +150°C ambient.
For engineers reviewing the MMBZ27VALQ-13-F datasheet, MMBZ27VALQ-13-F pinout, MMBZ27VALQ-13-F application, or MMBZ27VALQ-13-F equivalent, key selection criteria include clamping voltage at 40A (≤40V), low leakage (<1μA @ 22V), AEC-Q101 qualification, IATF 16949 manufacturing, and SOT23 footprint compatibility with automated placement.
Technical Context
This dual TVS operates in common-anode configuration, enabling bidirectional protection of two independent signal paths using a single device. Its 225mW steady-state power dissipation and 556°C/W junction-to-ambient thermal resistance are specified for FR-4 PCB mounting with 2oz copper.
The device uses silicon avalanche structure with +0.090%/°C temperature coefficient of breakdown voltage, ensuring predictable voltage shift over -55°C to +150°C operation. Clamping performance is validated per 10/1000μs waveform per R.E.A. standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 40W @ 1.0ms - withstands high-energy transients like ISO 7637-2 Pulse 1/2a/5a in automotive environments |
| Breakdown Voltage VBR | 25.65–28.35V @ IT = 1mA - ensures reliable triggering above 22V working voltage with margin |
| Clamping Voltage VC | ≤40V @ IPP = 40A - limits protected circuit voltage during surge, preserving downstream ICs |
| Reverse Leakage IR | ≤1μA @ VRWM = 22V - minimizes standby current impact on low-power sensor nodes |
| Operating Temp Range | -55°C to +150°C - supports under-hood and transmission control module deployment |
| AEC-Q101 Qualified | Yes - certified for automotive electronics per stress test requirements including HTOL, TCT, ESD-HBM/MM |
Pinout & Package
Package: SOT23 - surface-mount plastic case (UL 94V-0), 0.008g weight, moisture sensitivity level 1, lead-free matte tin plating over Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (Common) | Shared cathode connection point for both TVS elements; ties to ground reference plane |
| Pin 2 | Cathode 1 | Protects first signal line (e.g., CAN_H); reverse-biased during normal operation |
| Pin 3 | Cathode 2 | Protects second signal line (e.g., CAN_L); enables differential pair clamping with matched response |
Key Features
| Feature | Design Value |
|---|---|
| Dual Common-Anode TVS | Reduces board space by 50% vs. discrete single-channel TVS for differential bus protection |
| 40W Peak Pulse Rating | Meets ISO 16750-2 Level IV (50V/100ms) and ISO 7637-2 Pulse 5a (100V/100ms) immunity requirements |
| AEC-Q101 Qualification | Validated for automotive use with PPAP documentation support and IATF 16949 production traceability |
| Low 225mW Steady-State PD | Enables continuous operation in thermally constrained modules without derating penalties |
| Halogen/Antimony-Free | Complies with automotive "Green" material specs (<900ppm Br/Cl, <1000ppm Sb) for end-of-life recycling |

FAQ
What is the difference between MMBZ27VALQ-13-F and MMBZ27VAL-7-F?
The MMBZ27VALQ-13-F is AEC-Q101 qualified, manufactured in IATF 16949-certified facilities, and PPAP-capable for automotive applications; the MMBZ27VAL-7-F is commercial-grade with no automotive qualification or change control. Both share identical electrical specs and SOT23 packaging, but only the Q-suffix parts meet automotive reliability and documentation requirements.
Does MMBZ27VALQ-13-F support bidirectional transient suppression?
No - it is a dual unidirectional TVS in common-anode configuration, meaning each channel clamps only negative transients relative to ground. For bidirectional protection of a single line, a separate device like SMBJ27A would be required; this part protects two independent unidirectional signal paths.
What is the maximum clamping voltage at 10A peak pulse current?
Per the datasheet's Figure 7 curve (Ppk vs. pulse width), at 10A and 1ms pulse width, the clamping voltage is approximately 32V. This value is derived from the device's nominal breakdown voltage (27V) and dynamic impedance (~0.5Ω), consistent with the 40V max spec at 40A.
Can MMBZ27VALQ-13-F replace SMAJ27A in an existing design?
No - SMAJ27A is a single-channel DO-214AC package TVS with different footprint, thermal performance, and power rating (400W). MMBZ27VALQ-13-F is dual-channel, SOT23, 40W-rated, and intended for space-constrained automotive signal lines-not power-line protection. Footprint and surge capability are not interchangeable.
