Diodes Incorporated BAV116W-7-G

Overview

BAV116W-7-G from Diodes Incorporated is a surface-mount low-leakage silicon switching diode in SOD-123 package, rated for 130 V peak reverse voltage, 215 mA forward current, and exhibiting only 5 nA leakage at 75 V and 25°C. It serves as a precision clamping or signal-level protection device in high-impedance analog front-ends and timing circuits.

For engineers reviewing the BAV116W-7-G datasheet, BAV116W-7-G pinout, BAV116W-7-G application, or BAV116W-7-G equivalent, key selection criteria include ultra-low IR (5 nA @ 75 V), fast trr (3.0 µs), low VF (1.0 V @ 10 mA), thermal stability up to +150°C, and RoHS-compliant green packaging - critical for battery-powered sensor nodes and precision measurement systems.

Technical Context

The BAV116W-7-G is a planar epitaxial silicon PN junction diode optimized for low reverse leakage and stable forward conduction across wide temperature ranges. Its structure delivers consistent V(BR)R ≥130 V with minimal drift (±0% min/max spec) and maintains IR ≤80 nA even at TJ = 125°C under 75 V bias.

Designed for high-impedance signal path integrity, it features low CT (2.4–5 pF at 0 V, 1 MHz) and fast recovery (trr = 3.0 µs with IF = IR = 10 mA, RL = 100 Ω), enabling use in sample-and-hold circuits and RF detector stages where charge injection and capacitive loading must be minimized.

FAQ

What is the maximum reverse voltage the BAV116W-7-G can block continuously?

The BAV116W-7-G has a peak repetitive reverse voltage (VRRM) rating of 130 V, verified per JEDEC test conditions with IR = 100 µA. This rating applies at TA = +25°C and derates linearly above +25°C ambient per the published power derating curve, maintaining full 130 V capability up to +80°C with appropriate PCB copper area.

Does the BAV116W-7-G meet RoHS and halogen-free requirements?

Yes - the BAV116W-7-G is fully RoHS 2 compliant (2011/65/EU) with no intentionally added lead, and certified "Green" per Diodes Incorporated's definition: Br <900 ppm, Cl <900 ppm (total Br+Cl <1500 ppm), and Sb <1000 ppm. The SOD-123 molding compound is UL 94V-0 rated and halogen/antimony free.

How does the leakage current change at elevated temperature?

At VR = 75 V, IR increases from 5 nA at +25°C to 80 nA at +125°C, as specified in the Electrical Characteristics table. This 16× increase remains within design margins for most high-impedance bias networks, and Figure 3 in DS30291 confirms monotonic, predictable behavior without thermal runaway.

Is the SOD-123 package compatible with standard reflow profiles?

Yes - the BAV116W-7-G has Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and requires no baking prior to soldering. Its matte tin finish is compatible with SnPb and Pb-free reflow profiles, including IPC/JEDEC J-STD-020D peak temperatures up to 260°C for ≤60 seconds.
