Product details
Overview
BAS16-7-F from Diodes Incorporated is a surface-mount 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 fast switching performance in compact automated-assembly applications including signal routing in digital logic interfaces and transient suppression in low-voltage DC power rails.
For engineers reviewing the BAS16-7-F datasheet, BAS16-7-F pinout, BAS16-7-F application, or BAS16-7-F equivalent, key selection criteria include reverse recovery time under 4 ns, VF ≤ 0.855 V at 10 mA, VRM = 100 V, thermal resistance of 357 °C/W on FR-4, and RoHS-compliant green molding compound with matte tin terminations.
Technical Context
This diode operates as a unidirectional, low-capacitance (2.0 pF at 0 V) PN junction switch optimized for high-speed digital signal path control. Its 4.0 ns tRR and sub-1.0 V forward drop at 50 mA enable reliable operation in 5 V and 3.3 V logic-level clamping and steering circuits.
The device exhibits leakage current ≤1.0 µA at 75 V and 25 °C, rising to ≤50 µA at 150 °C - a critical parameter for thermally demanding industrial sensor front-ends and automotive body-control modules where ambient temperature exceeds 105 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time (tRR) | 4.0 ns - enables clean edge transitions in >10 MHz digital switching paths without tail current distortion |
| Peak Repetitive Reverse Voltage (VRRM) | 75 V - supports use in 48 V industrial bus monitoring and 24 V PLC I/O protection |
| Forward Voltage (VF) | 0.855 V @ 10 mA - minimizes conduction loss in low-power signal gating and level-shifting circuits |
| Reverse Leakage (IR) | 1.0 µA @ 75 V, 25 °C - ensures stable biasing in high-impedance analog sample-and-hold nodes |
| Thermal Resistance (RθJA) | 357 °C/W - requires minimal copper area (1″², 2 oz) for safe 350 mW dissipation at +25 °C ambient |
| Total Capacitance (CT) | 2.0 pF @ 0 V, 1 MHz - preserves signal integrity in RF detector inputs and clock distribution networks |
Pinout & Package
Package: SOT23 - surface-mount plastic package with 3-terminal configuration, 0.008 g mass, UL 94V-0 rating, and moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to higher-potential node in clamping or steering configurations; 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 ESD protection and logic-level translation |
| No Connection (Pin 3) | Unused leadframe tab | Electrically isolated; provides mechanical stability and thermal path to PCB copper via solder joint |
Key Features
| Feature | Design Value |
|---|---|
| Fast switching speed | 4.0 ns reverse recovery enables use in 10–50 MHz clock line steering without pulse distortion |
| Green molding compound | Halogen- and antimony-free formulation (<900 ppm Br/Cl, <1000 ppm Sb) meets IPC-1752A Class 3 reporting requirements |
| Lead-free plating | Matte tin over Alloy 42 leadframe ensures MIL-STD-202-compliant solderability and intermetallic reliability |
| SOT23 compatibility | Standardized footprint allows direct substitution into existing designs using MMBD4148 or MMBD914 layouts |
Applications
| Digital Logic Signal Steering | Low-Voltage Power Rail Clamping |
|---|---|
Use Scenario: Routing select lines between multiple microcontroller peripherals sharing a common bus. IC Role / Device Role / Timing Role: Unidirectional signal gate preventing backfeed during bus arbitration. Use Value: 4.0 ns tRR ensures no timing skew between 10 MHz address strobes and data valid windows. | Use Scenario: Suppressing inductive kickback from solenoid drivers in 5 V embedded control systems. IC Role / Device Role / Timing Role: Freewheeling diode providing low-loss return path during MOSFET turn-off. Use Value: 0.855 V VF at 10 mA reduces power loss by 35% versus legacy 1N4148 equivalents. |
| ESD Protection Front-End | High-Impedance Sensor Biasing |
Use Scenario: Input-stage transient suppression for RS-485 transceivers exposed to ±8 kV contact discharge. IC Role / Device Role / Timing Role: Low-capacitance (2.0 pF) shunt clamp limiting voltage overshoot without loading data lines. Use Value: Sub-1 µA IR at 25 °C prevents DC offset drift in precision differential receivers. | Use Scenario: Biasing photodiode anodes in battery-powered environmental light sensors. IC Role / Device Role / Timing Role: Reverse-biased guard ring isolating measurement node from supply rail noise. Use Value: 50 µA IR max at 150 °C maintains >10 GΩ effective isolation across full industrial temperature range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBD4148-7-F | Identical tRR (4.0 ns), same VF (0.855 V @ 10 mA), but IR = 5.0 µA @ 75 V - 5× higher leakage than BAS16-7-F | Less suitable for high-temperature sensor biasing where leakage-induced offset must be minimized | Select when cost is primary and leakage <5 µA is acceptable at 25 °C |
| MMBD914-7-F | Same package and pinout; VRRM = 75 V, but tRR = 4.0 ns and VF = 1.0 V @ 50 mA - 16.5% higher conduction loss | Acceptable in non-critical power gating but not recommended for high-frequency signal paths requiring minimal VF | Select only for legacy design continuity where VF tolerance >1.0 V is permitted |
Compared with MMBD4148-7-F and MMBD914-7-F, BAS16-7-F offers the lowest leakage at elevated temperature and tightest VF consistency across operating current - making it preferred for precision analog front-ends and thermally constrained industrial controllers.

FAQ
Is BAS16-7-F pin-compatible with MMBD4148-7-F and MMBD914-7-F?
Yes - all three parts use identical SOT23 packages with Anode (Pin 1), Cathode (Pin 2), and NC (Pin 3) pin assignments. The top-view marking layout and internal schematic match per Diodes' DS12003 Rev. 33-2, enabling direct PCB footprint reuse without layout modification.
What is the maximum junction temperature for continuous operation?
The absolute maximum junction temperature is +150 °C, with derated power dissipation beginning at +25 °C ambient. At +100 °C ambient, the device supports only 100 mW continuous dissipation due to its 357 °C/W RθJA on standard FR-4, as shown in Figure 1 of DS12003.
Does BAS16-7-F meet automotive qualification standards?
No - the standard BAS16-7-F is not AEC-Q101 qualified. Only the BAS16Q-7-F variant carries AEC-Q101 certification, PPAP capability, and IATF 16949 manufacturing compliance. Standard BAS16-7-F is intended for industrial and commercial applications.
How does the green molding compound affect reflow profile compatibility?
The halogen- and antimony-free green compound complies with JEDEC J-STD-020 moisture sensitivity level 1, allowing unlimited floor life and standard Pb-free reflow profiles (peak 260 °C, 30 sec). No special pre-bake or profile adjustments are required beyond standard SOT23 thermal mass guidelines.
