Product details
Overview
BAS40-06T-7-F from Diodes Incorporated is a surface-mount Schottky barrier diode rated for 40 V peak repetitive reverse voltage, 200 mA forward current, and 5.0 ns reverse recovery time, with ultra-low forward voltage (380 mV at 1 mA) optimized for high-frequency switching in portable power management and signal clamping circuits.
For engineers reviewing the BAS40-06T-7-F datasheet, BAS40-06T-7-F pinout, BAS40-06T-7-F application, or BAS40-06T-7-F equivalent, key selection criteria include low VF at low IF, sub-5 ns trr, SOT523 package footprint constraints, and ESD-protected junction guard ring implementation.
Technical Context
This Schottky diode uses a platinum-silicide (PtSi) or similar low-barrier metal-semiconductor junction to achieve fast switching and low forward voltage drop. Its PN junction guard ring structure provides transient suppression and ESD robustness up to ±8 kV HBM per AEC-Q101 requirements.
The device operates across –55 °C to +125 °C and exhibits 5.0 pF total capacitance at 0 V bias, enabling use in RF detector and high-speed logic interface applications where capacitive loading must remain below 6 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum blocking voltage before avalanche conduction begins; defines safe operating range in 3.3 V/5 V rail clamp designs |
| VF @ 1 mA | 380 mV - Enables efficient signal-level clamping with minimal voltage offset in analog front-ends |
| trr | 5.0 ns - Supports >100 MHz switching in sample-and-hold and pulse shaping circuits |
| CT @ 0 V | 5.0 pF - Limits parasitic loading on high-impedance nodes such as crystal oscillator feedback paths |
| IR @ 30 V | 200 nA - Ensures negligible leakage in battery-backed real-time clock backup circuits |
| PD | 150 mW - Sets thermal limit for continuous operation on FR-4 PCBs with standard pad layout |
Pinout & Package
Package: SOT523 - ultra-small plastic surface-mount package (1.60 mm × 1.60 mm × 0.75 mm), moisture sensitivity level 1, matte tin-plated terminals, 0.002 g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to higher-potential node during conduction; marked by cathode band on package top view |
| Cathode | Forward current exit / reverse blocking terminal | Connected to lower-potential node; serves as reference for clamping and ESD protection path |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 380 mV at 1 mA enables <100 µW dissipation in always-on bias networks |
| Fast switching speed | 5.0 ns trr supports clean edge integrity in 100+ MHz digital signal routing |
| PN junction guard ring | Provides ≥8 kV HBM ESD protection without external TVS components |
| Ultra-small SOT523 footprint | 1.6 mm × 1.6 mm area saves >60% board space vs. SOT23 in wearables and hearing aids |
Applications
| USB Data Line Protection | RF Detector Circuit |
|---|---|
Use Scenario: Clamping transient voltages on USB 2.0 D+/D− lines during hot-plug events. IC Role / Device Role / Timing Role: Signal-level bidirectional clamp protecting PHY transceivers from ESD and overshoot. Use Value: 380 mV VF ensures <±0.4 V clamping window at 1 mA, preserving USB eye diagram integrity. | Use Scenario: Demodulating AM signals in 2.4 GHz ISM-band receiver front-ends. IC Role / Device Role / Timing Role: Zero-bias RF envelope detector leveraging low CT and fast trr. Use Value: 5.0 pF capacitance and 5 ns recovery minimize distortion at 1–10 MHz IF frequencies. |
| Portable Battery Voltage Monitor | Logic-Level Translation Clamp |
Use Scenario: Monitoring Li-ion cell voltage via resistive divider while preventing reverse current leakage. IC Role / Device Role / Timing Role: Reverse-blocking element in high-impedance sensing path. Use Value: 200 nA IR at 30 V ensures <0.1% error in 1 MΩ divider networks over full temperature range. | Use Scenario: Level-shifting between 1.8 V I²C master and 3.3 V slave without dedicated translator IC. IC Role / Device Role / Timing Role: Passive clamp limiting high-side voltage excursion to VDD1 + VF. Use Value: 380 mV VF allows precise 1.8 V → 3.3 V translation with <100 mV margin above 3.3 V rail. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | Higher IFM (300 mA), larger SOD-523 package (1.7 mm × 1.3 mm), VF = 450 mV @ 1 mA | Less suitable for space-constrained RF detectors due to 15% larger footprint and 18% higher VF | Select when higher surge current rating is required and board area permits |
| RB520S-30T2R | Lower VRRM (30 V), same SOT-523 package, VF = 370 mV @ 1 mA, trr = 4 ns | Not usable in 40 V-rated systems; preferred only where 30 V max blocking suffices and sub-4 ns trr is critical | Select only if system reverse voltage never exceeds 30 V and <4 ns recovery is mandatory |
Compared with NSR0230HT1G and RB520S-30T2R, BAS40-06T-7-F uniquely balances 40 V blocking, 380 mV low-VF, 5 ns trr, and minimal SOT523 footprint-making it optimal for compact, mixed-signal applications demanding both voltage headroom and RF performance.

FAQ
What is the maximum junction temperature for BAS40-06T-7-F?
The absolute maximum junction temperature is +125 °C, with derating beginning at +25 °C ambient. At 85 °C ambient, maximum allowable power dissipation drops to 75 mW based on the 833 °C/W thermal resistance and linear derating curve shown in Figure 4 of DS30265 Rev. 14-2.
Is BAS40-06T-7-F qualified for automotive applications?
No-BAS40-06T-7-F is not AEC-Q101 qualified. While it features a PN guard ring for ESD robustness, Diodes specifies that automotive-grade versions require explicit AEC-Q101 qualification, PPAP capability, and IATF 16949 manufacturing; this part is intended for commercial and industrial use only.
How does the guard ring improve reliability?
The integrated PN junction guard ring surrounds the Schottky anode, providing a controlled lateral current path during ESD events. This structure prevents localized avalanche breakdown at the metal-semiconductor edge, enabling reliable operation at ±8 kV HBM without external protection components.
Can BAS40-06T-7-F replace BAS40-05T-7-F in existing designs?
Yes-BAS40-06T-7-F is functionally identical to BAS40-05T-7-F in electrical specifications and package. Both share identical VRRM (40 V), VF, trr, and SOT523 footprint; the suffix difference reflects internal wafer lot or test bin coding, not parametric variation.
