Product details
Overview
BAS40DW-06-7 from Diodes Incorporated is a dual-channel Schottky barrier diode array in SOT363 package, rated for 40 V peak reverse voltage, 200 mA continuous forward current, and 5.0 ns reverse recovery time. It delivers low forward voltage (380 mV at 1 mA) and ultra-low junction capacitance (5.0 pF at 0 V), enabling high-speed signal clamping and RF detector applications in portable power management circuits.
For engineers reviewing the BAS40DW-06-7 datasheet, BAS40DW-06-7 pinout, BAS40DW-06-7 application, or BAS40DW-06-7 equivalent, key selection criteria include its dual common-cathode configuration, 28 V RMS reverse rating, 600 mA non-repetitive surge capability, thermal resistance of 625 °C/W, and AEC-Q101 readiness for automotive signal conditioning designs.
Technical Context
This dual Schottky array integrates two independent anode terminals (A1, A2) sharing a common cathode (C1), forming a matched pair optimized for low-loss, high-frequency switching. Its guard-ringed PN junction enhances ESD robustness (per JESD22-A114) while maintaining fast transient response.
The device operates across –55 °C to +125 °C with 200 mW power dissipation on FR-4 board, and exhibits stable reverse leakage (<200 nA at 30 V) and minimal voltage-dependent capacitance (5.0 pF at 0 V, dropping to ~1.5 pF at 20 V), critical for RF mixer and sampling circuit integrity.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR20F40NXT5G | Single-channel, 40 V, 200 mA, SOD-523 package; no common-cathode topology | Requires two devices for dual-path function; lacks integrated matching and shared cathode routing | Select when discrete placement flexibility outweighs board-area savings and channel matching needs |
| BAT54CDW-7-F | Same SOT363 package and dual common-cathode structure; 30 V VRRM, 300 mV VF @ 1 mA | Lower reverse voltage rating limits use in 36 V automotive subsystems; lower VF improves efficiency at light loads | Prefer for 24 V systems where tighter forward voltage tolerance is prioritized over 40 V margin |
Compared with NSR20F40NXT5G and BAT54CDW-7-F, BAS40DW-06-7 uniquely balances 40 V blocking, 5 ns speed, and dual matched channels in SOT363-making it optimal for compact RF detectors and automotive signal clamps requiring both voltage headroom and timing precision.

FAQ
What is the pin configuration of BAS40DW-06-7?
The BAS40DW-06-7 uses a six-pin SOT363 package with active terminals A1, A2, and C1 configured as dual anodes and one common cathode. Pins C2, A3, and C3 are unconnected and must remain floating or grounded per layout guidelines to avoid parasitic coupling.
Does BAS40DW-06-7 meet AEC-Q101 requirements?
Yes-BAS40DW-06-7 is qualified to AEC-Q101 for stress testing including HTGB, TCT, and ESD (HBM ±8 kV). It is manufactured in IATF 16949-certified facilities and supports PPAP documentation for automotive Tier-1 suppliers.
How does the guard ring improve reliability?
The integrated PN junction guard ring suppresses edge leakage currents and prevents premature avalanche breakdown during ESD events. This structure enables the device to pass JESD22-A114 (±8 kV HBM) without external protection components in most signal-line applications.
Can BAS40DW-06-7 replace BAT54CDW-7-F in existing designs?
Yes, with verification of reverse voltage margin: BAS40DW-06-7 offers 40 V VRRM versus 30 V for BAT54CDW-7-F, making it suitable for higher-voltage rails. Layout is identical (SOT363), but forward voltage is slightly higher (380 mV vs. 300 mV at 1 mA), affecting light-load efficiency.
