Product details
Overview
MMBZ10VAL-7-F from Diodes Incorporated is a unidirectional dual TVS diode in common-anode SOT23 package, rated for 24W peak pulse power (1.0ms), 10V reverse standoff voltage (VRWM = 10V), and 14.2V clamping voltage at 1.7A IPP. It provides ESD and transient protection for low-voltage data lines in automotive infotainment interfaces.
For engineers reviewing the MMBZ10VAL-7-F datasheet, MMBZ10VAL-7-F pinout, MMBZ10VAL-7-F application, or MMBZ10VAL-7-F equivalent, key selection criteria include its 10V VRWM tolerance, 225mW steady-state power dissipation, AEC-Q101 qualification, and SOT23 footprint compatibility with automated PCB assembly.
Technical Context
This dual TVS operates in common-anode configuration, enabling bidirectional protection of two signal paths using a single anode connection. Its 10V reverse standoff voltage ensures reliable blocking below system operating voltage, while the 14.2V clamping voltage limits transients during 1.0ms 24W pulses.
The device features low leakage (<0.3µA @ VRWM), +0.065%/°C temperature coefficient of breakdown voltage, and is qualified to AEC-Q101 for automotive reliability. Thermal resistance is 556°C/W on FR-4 board, supporting operation from –55°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 10 V - Maximum continuous reverse working voltage before conduction begins |
| VBR (min/typ/max) | 9.5 / 10 / 10.5 V - Breakdown occurs within this range at 1mA test current |
| VC @ IPP | 14.2 V @ 1.7 A - Clamps transient energy to ≤14.2V during 1.0ms pulse |
| PPK | 24 W - Peak pulse power handling per channel under standard 1.0ms waveform |
| PD | 225 mW - Steady-state power dissipation limit on FR-4 PCB |
| TC of VBR | +0.065 %/°C - Predictable drift of breakdown voltage with temperature |
| IR @ VRWM | ≤0.3 µA - Minimal leakage current ensures low standby power impact |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Single-channel SMA package; 10V VRWM, 27.2V VC @ 12.1A; higher clamping voltage, larger footprint | Requires two devices for dual-line protection; unsuitable for space-constrained SOT23 layouts | Choose when higher peak current (12.1A vs. 1.7A) is required and board area permits SMA footprint |
| DF2S7.0FUTM | Dual-channel SOT-323; 7V VRWM, 12.5V VC @ 1.5A; lower standoff voltage, smaller package | Better suited for 3.3V/5V systems; not rated for 12V automotive supply rails | Prefer for compact 3.3V IoT interfaces where 10V standoff is excessive and layout density is critical |
Compared with SMAJ10A and DF2S7.0FUTM, MMBZ10VAL-7-F uniquely balances 10V system compatibility, SOT23 miniaturization, and AEC-Q101 qualification-making it optimal for dual-line protection in automotive and industrial 12V domains where footprint and reliability are co-prioritized.

FAQ
What is the polarity configuration of MMBZ10VAL-7-F?
MMBZ10VAL-7-F uses a common-anode dual TVS configuration: Pins 1 and 2 are anodes (internally tied), and Pin 3 serves as the cathode for one channel while Pin 2 functions as the cathode for the second channel. This allows independent clamping of two signal lines to a shared reference node.
Is MMBZ10VAL-7-F still in active production?
No-MMBZ10VAL-7-F is marked obsolete in Diodes' official documentation (DS43615 Rev. 1–4, April 2021). However, Aetrix Electronics maintains legacy inventory and offers lifecycle management support, including cross-reference guidance and last-time-buy planning for ongoing production programs.
Can MMBZ10VAL-7-F be used for bidirectional signal protection?
Yes-when externally biased with appropriate pull-up/down resistors, the common-anode structure supports bidirectional transient suppression. The datasheet confirms bidirectional clamping capability in Figure 3 (capacitance vs. bias), though its primary rating is unidirectional 24W peak power per channel.
What is the thermal derating behavior above 25°C ambient?
Per Figure 1 in DS43615, MMBZ10VAL-7-F's peak pulse power derates linearly: at 85°C ambient, maximum PPK drops to ~75% of 24W (~18W); at 125°C, it falls to ~45% (~10.8W). Steady-state PD follows Figure 5, reducing from 225mW at 25°C to ~120mW at 85°C on FR-4 board.
