Product details

Overview

BAS40-06-7-F from Diodes Incorporated is a surface-mount Schottky barrier diode in SOT23 package, rated for 40 V peak reverse voltage, 200 mA continuous forward current, and 380 mV typical forward voltage at 1 mA. It features fast 5.0 ns reverse recovery time, 4.0 pF total capacitance at 0 V, and PN junction guard ring for transient/ESD protection-used in high-frequency switching and low-loss signal routing in portable power management.

For engineers reviewing the BAS40-06-7-F datasheet, BAS40-06-7-F pinout, BAS40-06-7-F application, or BAS40-06-7-F equivalent, key selection criteria include its low VF at low IF, sub-5 ns trr, SOT23 thermal resistance (357 °C/W), RoHS-compliant matte tin plating, and AEC-Q101 qualification of the Q-grade variant.

Technical Context

This Schottky diode uses a planar epitaxial structure with integrated PN junction guard ring to suppress edge breakdown and improve ESD robustness without compromising switching speed. Its low barrier height enables 380 mV VF at 1 mA while maintaining 200 nA typical IR at 30 V reverse bias.

The device operates across –55 °C to +125 °C and derates linearly above 25 °C ambient, delivering 350 mW power dissipation on FR-4 with recommended pad layout. Total capacitance remains stable below 5.0 pF up to 30 V reverse bias, supporting RF detector and high-speed clamp applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	40 V - Maximum DC blocking voltage before avalanche; sets upper limit for clamping and rectification in 3.3 V–24 V systems.
I_F Continuous	200 mA - Sustained forward current capability; supports load-switching and OR-ing in compact DC-DC output stages.
V_F Max	1.0 V @ 40 mA - Low conduction loss ensures minimal voltage drop in battery-fed signal paths and level-shifting circuits.
t_rr	5.0 ns - Enables operation up to ~70 MHz in snubbing and high-frequency demodulation without tail current issues.
C_T	4.0–5.0 pF @ 0 V - Low junction capacitance preserves signal integrity in RF detector and sampling gate designs.
I_R Max	200 nA @ 30 V - Ensures negligible leakage in precision bias networks and high-impedance sensor interfaces.

Pinout & Package

Package: SOT23 (Standard), 3-terminal surface-mount plastic package per JEDEC TO-236AB; dimensions: 2.90 mm × 1.30 mm × 1.025 mm; weight ≈ 0.008 g; moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning

Cathode (Pin 2)	Forward current exit / reverse blocking terminal	Connected to higher-potential node; ties to ground or supply rail in protection circuits.
No-Connect (Pin 3)	Internal die attach pad (non-bonded)	Thermally conductive but electrically isolated; used for mechanical stability and heat spreading on PCB.

Key Features

Feature	Design Value

IC Role / Device Role / Timing Role: Schottky detector diode in passive envelope follower circuit.

Use Value: 4.0 pF C_T and 5.0 ns t_rr preserve high-frequency response; 380 mV V_F enables sensitivity down to –20 dBm input.

Use Scenario: Reverse-polarity and ESD protection on USB 2.0 VBUS line in portable accessories.

IC Role / Device Role / Timing Role: Low-capacitance clamp diode between VBUS and GND.

Use Value: 200 nA I_R prevents standby drain; guard ring withstands ±8 kV HBM ESD pulses without degradation.

Low-Voltage OR-ing

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NSR0230HT1G	30 V V_RRM, 200 mA I_F, 420 mV V_F @ 10 mA, 10 pF C_T	Lower voltage rating; higher capacitance limits RF use above 100 MHz.	Select when cost sensitivity outweighs RF performance and 40 V margin is unnecessary.
RB520S-30T1G	30 V V_RRM, 200 mA I_F, 340 mV V_F @ 1 mA, 5.5 pF C_T, 10 ns t_rr	Higher trr and C_T reduce high-frequency fidelity; optimized for general-purpose rectification.	Prefer for low-noise analog biasing where speed is secondary to ultra-low V_F.

Compared with NSR0230HT1G and RB520S-30T1G, BAS40-06-7-F delivers superior high-frequency response (5 ns trr, 4 pF CT) and higher reverse voltage margin (40 V), making it optimal for RF detection and fast transient clamping where both speed and robustness are critical.

FAQ

Is BAS40-06-7-F AEC-Q101 qualified?

No - only the Q-grade variant (BAS40-06Q-7-F) is AEC-Q101 qualified, PPAP capable, and manufactured in IATF16949-certified facilities. The standard BAS40-06-7-F is intended for commercial and industrial applications, not automotive safety-critical systems.

What is the maximum operating temperature for BAS40-06-7-F?

The device operates from –55 °C to +125 °C junction temperature. At 25 °C ambient, it supports 350 mW power dissipation; derating begins linearly above 25 °C, reaching zero dissipation at 125 °C ambient on FR-4 with recommended pad layout.

Does BAS40-06-7-F have a built-in ESD protection structure?

Yes - it integrates a PN junction guard ring that provides inherent transient suppression and ESD robustness. Typical HBM ESD rating exceeds 8 kV, eliminating need for external TVS diodes in many low-energy interface protection schemes.

Can BAS40-06-7-F replace BAS40-04-7-F or BAS40-05-7-F in a design?

Yes - all three share identical SOT23 package, electrical ratings (40 V V_RRM, 200 mA I_F), and thermal specs. Differences are limited to date-code marking and internal process optimization; no functional or reliability impact has been documented across these variants.
