Product details
Overview
MMBD914-7 from Diodes Incorporated is a surface-mount fast-switching silicon switching diode in SOT23 package, rated for 75 V peak repetitive reverse voltage, 300 mA forward current, and 4.0 ns reverse recovery time. It delivers low forward voltage (0.715 V at 1 mA) and low leakage (<1.0 µA at 75 V), making it suitable for high-speed signal routing and clamp protection in digital logic interfaces.
For engineers reviewing the MMBD914-7 datasheet, MMBD914-7 pinout, MMBD914-7 application, or MMBD914-7 equivalent, key selection criteria include reverse recovery speed, junction capacitance (2.0 pF), thermal resistance (357 °C/W), RoHS/Green compliance, and SOT23 footprint compatibility with automated PCB assembly.
Technical Context
This diode operates as a unidirectional voltage-controlled switch with a planar epitaxial construction optimized for rapid carrier recombination. Its 4.0 ns tRR enables reliable operation in 10–50 MHz digital switching circuits, while its 2.0 pF junction capacitance minimizes signal distortion in high-frequency waveform shaping.
The device features a 75 V VRWM rating and maintains <1.0 µA IR at full rated reverse voltage and 25°C, supporting stable DC blocking in level-shifting and input protection stages. Thermal performance is defined for FR-4 PCB mounting with 1-inch² 2 oz copper pad, yielding 357 °C/W RθJA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 75 V - Maximum continuous reverse voltage before breakdown; sets safe operating limit for clamping and isolation circuits. |
| tRR | 4.0 ns - Measured under IF = IR = 10 mA, IRR = 1 mA; ensures minimal switching delay in TTL/CMOS interface protection. |
| VF | 0.715 V @ 1 mA - Low forward drop reduces power loss and voltage offset in signal path applications. |
| CT | 2.0 pF @ 0 V, 1 MHz - Low junction capacitance preserves signal integrity in >10 MHz data lines and RF detector inputs. |
| IF | 300 mA - Continuous forward current rating; supports robust surge handling in transient suppression networks. |
| RθJA | 357 °C/W - Thermal resistance on standard FR-4 layout; determines maximum ambient temperature for sustained 300 mA operation. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with 3 terminals, 0.008 g mass, UL 94V-0 rating, and matte tin-plated alloy 42 leadframe compatible with lead-free reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to higher-potential node during conduction; polarity-marked by cathode band on package top view. |
| Cathode (Pin 2) | Forward current exit / reverse blocking terminal | Internally tied to substrate; serves as reference node for clamping and ESD protection paths. |
| No-Connect (Pin 3) | Unused internal lead | Electrically isolated; provides mechanical stability and thermal path but no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| Fast switching speed | 4.0 ns reverse recovery time enables use in 25+ MHz clock distribution and pulse shaping circuits. |
| SOT23 surface-mount package | Standardized 3-pin footprint compatible with automated pick-and-place and reflow processes; saves board space vs. DO-35. |
| Lead-free and RoHS compliant | Fully compliant with EU Directive 2015/863/EU; uses halogen- and antimony-free molding compound (Br+Cl <1500 ppm). |
| Low leakage current | <1.0 µA at 75 V and 25°C ensures minimal standby power loss in battery-powered sensor front-ends. |
Applications
| Digital Logic Interface Protection | High-Speed Pulse Clamping |
|---|---|
Use Scenario: Protecting CMOS/TTL input pins from overshoot and ESD transients in industrial control I/O modules. IC Role / Device Role / Timing Role: Fast-acting shunt clamp that conducts only when input exceeds VCC + 0.7 V or drops below GND − 0.7 V. Use Value: 4.0 ns tRR prevents false triggering during nanosecond-scale noise spikes without distorting valid logic edges. | Use Scenario: Conditioning square-wave signals in FPGA clock fanout buffers and ADC sampling clocks. IC Role / Device Role / Timing Role: Edge sharpening via controlled forward conduction and rapid reverse recovery. Use Value: 2.0 pF CT and low VF minimize rise-time degradation and duty-cycle distortion in 20–50 MHz waveforms. |
| DC Level Shifting | Sample-and-Hold Input Protection |
Use Scenario: Biasing analog sensor outputs to match ADC input range in automotive cabin temperature monitoring systems. IC Role / Device Role / Timing Role: Passive forward-biased voltage offset element with predictable 0.715 V drop at 1 mA. Use Value: Tight VF tolerance (±0.14 V across 1–150 mA) ensures consistent offset calibration across temperature and production lots. | Use Scenario: Guarding precision sample-and-hold amplifier inputs against overvoltage during multiplexer channel switching. IC Role / Device Role / Timing Role: Low-capacitance reverse-biased guard diode limiting input swing to ±0.7 V beyond rails. Use Value: 2.0 pF CT avoids degrading acquisition settling time; <1.0 µA IR prevents DC error injection into high-impedance hold capacitors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast-switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS16-7-F | Identical VRWM (75 V), tRR (4.0 ns), and SOT23 package; same die construction per Diodes DS12003 Rev. 33. | No functional difference; BAS16-7-F and MMBD914-7-F share identical electrical specs and marking conventions. | Select based on inventory availability or legacy BOM alignment; both meet same qualification standards. |
| MMBD4148-7-F | Same VRWM (75 V), tRR (4.0 ns), and SOT23 package; minor VF variance (0.72 V vs. 0.715 V @ 1 mA) within test tolerance. | No application impact; all three parts (BAS16/MMBD4148/MMBD914) are cross-listed in Diodes' datasheet as functionally interchangeable. | Prefer MMBD4148-7-F if sourcing from distributors with stronger stock depth; identical performance in all validated use cases. |
Compared with BAS16-7-F and MMBD4148-7-F, MMBD914-7 offers identical switching speed, voltage ratings, and thermal behavior-differences are limited to part numbering and historical branding, not design intent or electrical behavior.

FAQ
Is MMBD914-7 pin-compatible with BAS16-7-F and MMBD4148-7-F?
Yes. All three parts use the SOT23 package with identical pin 1 (anode), pin 2 (cathode), and pin 3 (no-connect) configuration. The internal schematic and polarity marking (cathode band) are consistent across these Diodes part numbers per DS12003 Rev. 33.
What is the maximum junction temperature for continuous operation?
The MMBD914-7 has an operating junction temperature range of −55°C to +150°C. At 300 mA forward current and 25°C ambient, junction temperature rise is ~107°C (300 mA² × 357 °C/W × 0.357 W), staying within the 150°C limit only with adequate PCB copper area or forced cooling.
Does MMBD914-7 meet AEC-Q101 for automotive use?
No. The MMBD914-7 is not AEC-Q101 qualified. For automotive applications, Diodes specifies the BAS16Q variant (e.g., BAS16Q-7-F), which is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities.
How does moisture sensitivity affect MMBD914-7 handling?
The MMBD914-7 is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/85% RH without baking prior to reflow. No floor life limitation applies, simplifying SMT line logistics for high-mix production environments.
