Product details
Overview
BAS40-00-E3-18 from Vishay Semiconductors is a single silicon Schottky diode in SOT-23 package, rated for 40 V repetitive peak reverse voltage, 200 mA forward current, and 5 ns reverse recovery time. It delivers low forward voltage (380 mV at 1 mA) and ultra-low leakage (≤100 nA at 30 V), enabling efficient signal clamping and high-speed switching in portable power management circuits.
For engineers reviewing the BAS40-00-E3-18 datasheet, BAS40-00-E3-18 pinout, BAS40-00-E3-18 application, or BAS40-00-E3-18 equivalent, key selection criteria include its 40 V VRRM, 5 ns trr, SOT-23 footprint compatibility, RoHS-compliant commercial-grade qualification, and verified performance in 1 MHz RF detector and battery protection paths.
Technical Context
This Schottky diode operates with a metal–semiconductor junction to achieve fast switching and low forward voltage drop, distinguishing it from standard PN-junction diodes. Its guardring-protected structure enhances ESD robustness without compromising speed or leakage.
The device is characterized under standard test conditions (Tamb = 25 °C) with pulse-tested parameters including 40 mA forward voltage (1.0 V max) and 4–5 pF junction capacitance at 0 V bias, supporting stable RF and high-frequency sampling applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | Same SOT-23 package; 30 V VRRM, 200 mA IF, 0.45 V VF @ 10 mA - lower voltage rating, higher VF | Not suitable for 36 V auxiliary rails or 40 V surge protection; acceptable for 3.3 V logic clamping only | Select when system max reverse voltage ≤30 V and cost sensitivity outweighs 40 V margin |
| 1N5711 | DO-35 glass package; 70 V VRRM, 150 mA IF, 1.0 V VF @ 10 mA - higher voltage, larger size, slower trr (~10 ns) | Requires through-hole layout; unsuitable for high-density RF layouts due to parasitic inductance and capacitance | Choose only for legacy through-hole designs needing >40 V rating and where board space permits |
Compared with NSR0230HT1G and 1N5711, the BAS40-00-E3-18 uniquely balances 40 V rating, 5 ns speed, SOT-23 scalability, and sub-400 mV low-current VF-making it optimal for modern compact, high-frequency, and battery-sensitive designs where voltage margin, speed, and footprint are jointly constrained.

FAQ
What is the maximum reverse voltage rating for BAS40-00-E3-18?
The BAS40-00-E3-18 has a repetitive peak reverse voltage (VRRM) rating of 40 V, verified per Vishay's datasheet Rev. 2.2 (Document Number: 85701). This rating applies under standard ambient conditions and defines the maximum sustained reverse bias the BAS40-00-E3-18 can block without breakdown. Exceeding this value risks irreversible junction damage.
Is BAS40-00-E3-18 RoHS-compliant and what does the "E3" suffix indicate?
Yes, BAS40-00-E3-18 is RoHS-compliant. The "E3" suffix denotes Vishay's standard commercial-grade packaging: lead (Pb)-free terminations, halogen-free molding compound, and compliance with EU Directive 2011/65/EU. It is not AEC-Q101 qualified-that requires the "HE3" suffix variant.
What is the typical forward voltage of BAS40-00-E3-18 at 1 mA forward current?
The typical forward voltage (VF) of BAS40-00-E3-18 is 380 mV at 1 mA and 25 °C, as specified in the Electrical Characteristics table of the official datasheet. This low VF enables precise biasing in micropower analog stages and improves efficiency in low-current signal-path applications involving the BAS40-00-E3-18.
Does BAS40-00-E3-18 have a built-in ESD protection structure?
Yes, the BAS40-00-E3-18 incorporates a PN junction guardring that provides inherent protection against electrostatic discharge events. This feature is explicitly documented in the Features section of the Vishay datasheet and eliminates the need for external ESD components in many low-energy signal-path applications using the BAS40-00-E3-18.
What is the reverse recovery time (trr) of BAS40-00-E3-18 and how is it measured?
The reverse recovery time (trr) of BAS40-00-E3-18 is 5 ns, measured under the condition: IF = IR = 10 mA, iR = 1 mA, RL = 100 Ω. This value reflects the diode's ability to transition rapidly from conduction to blocking state, critical for high-frequency rectification and detection tasks where the BAS40-00-E3-18 is deployed.
