Product details
Overview
DG401BDY-T1-E3 from Vishay Siliconix is a dual single-pole single-throw (SPST) CMOS analog switch IC designed for bidirectional signal routing in precision analog systems. It delivers 23 Ω on-resistance, ±15 V analog signal range, and 100 ns typical turn-on time, enabling low-distortion audio/video switching and sample-and-hold circuits in battery-powered instrumentation.
For engineers reviewing the DG401BDY-T1-E3 datasheet, DG401BDY-T1-E3 pinout, DG401BDY-T1-E3 application, or DG401BDY-T1-E3 equivalent, key selection criteria include guaranteed break-before-make timing (not applicable to DG401B), dual-supply operation up to ±22 V, low 40 pA channel-on leakage, and SOIC-16 lead-free packaging compliant with RoHS requirements.
Technical Context
The DG401BDY-T1-E3 uses Vishay's high-voltage silicon gate process to achieve 44 V supply rating and flat on-resistance over full ±15 V analog swing. Its TTL/CMOS-compatible control inputs accept logic thresholds of ≤0.8 V (low) and ≥2.4 V (high), supporting direct interface with microcontrollers without level-shifting.
Each SPST switch conducts equally in both directions when on and blocks signals up to 30 V peak-to-peak when off. The device supports single-supply operation from 5 V to 36 V and dual-supply operation from ±5 V to ±22 V, with supply currents under 1 mA across temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single SPST, 35 Ω RDS(on), 125 ns ton, ±15 V range, 16-pin SOIC | Lower channel count - requires two devices to match DG401BDY-T1-E3's dual SPST functionality | Select when lower on-resistance tolerance or extended temperature range (–40°C to +85°C) is prioritized over integrated dual-channel density |
| ADG1419BRUZ | Dual SPST, 1.3 Ω RDS(on), 120 ns ton, ±15 V range, 16-pin TSSOP | Higher performance but higher cost and different package - not drop-in compatible due to TSSOP footprint | Select when ultra-low on-resistance is critical for precision current-sensing or low-gain amplifier feedback paths |
Compared with MAX4617ESE+ and ADG1419BRUZ, the DG401BDY-T1-E3 offers balanced performance at lower cost in standard SOIC-16 packaging, making it optimal for space-constrained industrial and medical designs where 23 Ω on-resistance and 100 ns speed meet system requirements without premium pricing.

FAQ
What is the maximum analog signal voltage supported by the DG401BDY-T1-E3?
The DG401BDY-T1-E3 supports an analog signal range of ±15 V, meaning it can pass or block signals spanning –15 V to +15 V relative to its V– and V+ rails. This is confirmed in the "Analog signal range" specification (–15 V to +15 V) under operating conditions with V+ = 15 V and V– = –15 V. Exceeding this range risks clamping by internal protection diodes.
Does the DG401BDY-T1-E3 support single-supply operation?
Yes, the DG401BDY-T1-E3 supports single-supply operation from 5 V to 36 V, as documented in the Product Summary table. In this mode, V– is connected to ground, V+ supplies the positive rail, and analog signals swing from 0 V to V+. The device maintains specified RDS(on), leakage, and switching performance across this range.
Is break-before-make timing guaranteed for the DG401BDY-T1-E3?
No, break-before-make timing is not guaranteed for the DG401BDY-T1-E3. The datasheet explicitly states this feature applies only to the DG403B and DG405B variants. The DG401BDY-T1-E3 contains two independent SPST switches with no interlock or timing coordination between them - each operates autonomously based on its respective IN1 or IN2 control signal.
What is the thermal derating behavior of the DG401BDY-T1-E3 above 75 °C?
Above 75 °C, the DG401BDY-T1-E3 power dissipation must be derated at 7.6 mW/°C for the 16-pin narrow SOIC package, as specified in Note d of the Absolute Maximum Ratings table. For example, at 100 °C ambient, allowable power drops by (100 – 75) × 7.6 mW = 190 mW from the 600 mW rated limit, leaving 410 mW maximum continuous dissipation.
How does the -E3 suffix in DG401BDY-T1-E3 affect soldering and reliability?
The -E3 suffix indicates 100 % matte tin device terminations, confirming lead (Pb)-free compliance per RoHS. These terminations are compatible with standard SnPb and lead-free reflow profiles (per JEDEC J-STD-020), exhibit no whisker growth risk under typical operating conditions, and maintain mechanical and electrical reliability equivalent to legacy tin-lead finishes when processed per Vishay's recommended thermal profiles.
