Product details

Overview

MMBD914-7-F 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 serves as a general-purpose signal-level switching element in high-speed digital logic interfaces, clamping circuits, and waveform shaping networks.

For engineers reviewing the MMBD914-7-F datasheet, MMBD914-7-F pinout, MMBD914-7-F application, or MMBD914-7-F equivalent, key selection criteria include reverse recovery speed, low forward voltage at 10–50 mA drive levels, thermal resistance (357 °C/W), and RoHS-compliant green packaging suitable for automated SMT assembly.

Technical Context

This diode employs a planar epitaxial construction optimized for rapid carrier recombination, enabling sub-5 ns reverse recovery under 10 mA IF/IR test conditions with 100 Ω load. Its junction capacitance remains stable at 2.0 pF at 0 V bias and 1 MHz, supporting high-frequency signal routing without parasitic loading.

The device operates across –55 °C to +150 °C and maintains leakage below 1.0 µA at 75 V reverse bias and 25 °C ambient, while derating to 350 mW maximum power dissipation on standard FR-4 PCB layout per JEDEC standards.

Key Specifications

Parameter	Value and Actual Design Meaning
VR_RMS	53 V - defines safe AC-coupled blocking capability in signal path applications
t_RR	4.0 ns - enables reliable operation in >100 MHz digital switching and pulse shaping
V_F @ 10 mA	0.855 V max - ensures low conduction loss in logic-level clamp and steering circuits
I_R @ 75 V	1.0 µA max - guarantees minimal signal leakage in high-impedance analog sampling nodes
C_T @ 0 V	2.0 pF - limits capacitive loading on RF or high-speed data lines
R_θJA	357 °C/W - determines thermal rise on standard 1-inch² 2 oz copper pad; requires layout-aware thermal design

Pinout & Package

Package: SOT23 - surface-mount plastic package with matte tin-plated alloy 42 leadframe, moisture sensitivity level 1, UL 94V-0 rating, and 0.008 g mass.

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 electrical specs (t_RR, V_F, V_R) and SOT23 package; same Diodes die, differentiated only by orderable part number and traceability marking	No functional difference; used interchangeably in all non-automotive designs	Select BAS16-7-F when legacy BOM references require exact part number match without date-code constraints
MMBD4148-7-F	Same t_RR (4.0 ns), but slightly higher V_F (0.875 V max @ 10 mA) and identical leakage (1.0 µA @ 75 V); identical SOT23 mechanicals	Marginally higher conduction loss in low-voltage logic clamps; otherwise functionally interchangeable	Prefer MMBD4148-7-F where legacy schematics specify that part number or when sourcing from distributors with larger stock depth

Compared with BAS16-7-F and MMBD4148-7-F, MMBD914-7-F offers identical core switching performance but distinct traceability and date-code marking conventions-making it optimal for new designs requiring explicit Diodes product-line alignment without automotive qualification overhead.

FAQ

Is MMBD914-7-F AEC-Q101 qualified?

No. MMBD914-7-F is not AEC-Q101 qualified. The automotive-grade variant is the BAS16Q series, which undergoes additional change control, PPAP documentation, and IATF 16949-certified manufacturing. MMBD914-7-F is intended for commercial and industrial applications only.

What is the maximum operating temperature for continuous use?

The MMBD914-7-F has a specified operating junction temperature range of –55 °C to +150 °C. For continuous operation at full 300 mA forward current, PCB thermal design must ensure junction temperature stays within this limit-typically requiring derating above +70 °C ambient per the published power derating curve.

Can MMBD914-7-F replace 1N4148 in SOT23 footprint designs?

Yes, MMBD914-7-F is a direct SOT23-packaged equivalent of the through-hole 1N4148, matching its key parameters: 75 V V_R, 4.0 ns t_RR, and 0.855 V V_F @ 10 mA. It supports automated placement and reflow, unlike axial-lead 1N4148, and adds RoHS/Green compliance.

Does the SOT23 package include a thermal pad or exposed die attach?

No. The SOT23 package for MMBD914-7-F uses a standard three-terminal leadframe with no exposed thermal pad. Pin 3 is an internal die attach paddle electrically isolated from terminals and not connected to any external circuit node-thermal management relies solely on conduction through pins 1 and 2 to PCB copper.
