Product details
Overview
DG2520DV-T1-E3 from Vishay Siliconix is a sub-Ω, low-voltage SPDT analog switch with overcurrent protection, designed for signal routing in USB/UART and audio/video paths. It operates from 1.8 V to 5.5 V, delivers 0.4 Ω typical on-resistance at 4.5 V, supports 1.6 V logic-compatible control, and features break-before-make switching with 30 ns typical turn-on time (V+ = 4.5 V).
For engineers reviewing the DG2520DV-T1-E3 datasheet, DG2520DV-T1-E3 pinout, DG2520DV-T1-E3 application, or DG2520DV-T1-E3 equivalent, key selection criteria include on-resistance flatness (0.2 Ω), overcurrent trip threshold (1.7 A), charge injection (224 pC), and TSOP-6 package compatibility for space-constrained portable designs.
Technical Context
The DG2520DV-T1-E3 implements a CMOS-based SPDT architecture with integrated overcurrent protection that activates at ~0.6 V across the switch channel, pulsing off for <1 µs before entering 5 ms auto-recovery cycling under sustained short conditions. Its break-before-make timing ensures no signal shorting during state transitions.
It uses Vishay's proprietary sub-micron process to achieve low power consumption (22 µA max supply current) and high linearity (0.06 Ω rON matching), enabling clean analog signal routing without distortion across full rail-to-rail voltage swing (0 V to V+).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 1.8 V to 5.5 V - enables direct interface with Li-ion battery, 3.3 V, and 5 V systems without level shifting |
| On-Resistance (rON) | 0.4 Ω typical at 4.5 V - minimizes insertion loss and voltage drop in high-current analog paths |
| rON Flatness | 0.2 Ω max - maintains consistent gain and THD across full signal range (0 V to V+) |
| Break-Before-Make Time | 1–15 ns - prevents momentary shorting between NC and NO during switching |
| Overcurrent Threshold | 1.7 A typical - protects downstream circuitry from fault currents while allowing transient peaks |
| -3 dB Bandwidth | 40 MHz - supports USB 1.1 (12 Mbps) and standard-definition video signal integrity |
| Charge Injection | 224 pC - limits glitch amplitude when switching DC-coupled signals into high-impedance nodes |
Pinout & Package
TSOP-6 surface-mount package (2.1 mm × 1.6 mm × 0.9 mm), lead (Pb)-free with matte tin terminations per RoHS compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NO | Normally Open switch terminal | Connects to COM only when IN = logic high; used for active signal path selection |
| 2 - COM | Common analog I/O node | Shared connection point for bidirectional analog signal routing between NO and NC |
| 3 - NC | Normally Closed switch terminal | Connects to COM only when IN = logic low; provides default signal path |
| 4 - IN | Digital control input | 1.6 V logic-compatible; drives internal CMOS gate to select NO or NC path |
| 5 - V+ | Positive supply rail | Provides bias for analog switch core and protection circuitry; accepts 1.8–5.5 V |
| 6 - GND | Analog/digital reference ground | Return path for signal current and supply current; must be low-impedance for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Sub-Ω on-resistance | 0.4 Ω typical at 4.5 V reduces signal attenuation and thermal drift in precision analog paths |
| Overcurrent protection | Auto-cycling shutdown (1 µs off / 5 ms on) prevents latch-up and damage during shorts |
| 1.6 V logic compatibility | Operates reliably with 1.8 V I/O microcontrollers without external level shifters |
| Low charge injection | 224 pC limits output glitches when switching DC-biased sensors or audio sources |
| Full rail signal swing | Supports 0 V to V+ analog signals - preserves dynamic range in battery-powered audio/video systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4680EUT+T | Higher rON (0.9 Ω typ), no integrated overcurrent protection, 1.8–5.5 V supply | Lacks fault protection; requires external current limiting for short-circuit scenarios | Select when overcurrent protection is unnecessary and cost sensitivity outweighs robustness needs |
| ADG721BRMZ-REEL7 | Lower bandwidth (200 MHz), higher charge injection (30 pC), same TSOP-6 package | Better for high-frequency RF switching but less suitable for low-distortion audio due to higher rON flatness (0.3 Ω) | Select when ultra-fast switching dominates over analog linearity and fault tolerance |
Compared with MAX4680EUT+T and ADG721BRMZ-REEL7, the DG2520DV-T1-E3 uniquely combines sub-Ω on-resistance, integrated overcurrent protection, and 1.6 V logic compatibility in a TSOP-6 footprint-making it optimal for battery-powered USB/audio systems requiring both performance and fault resilience.

FAQ
What is the maximum continuous current rating for the DG2520DV-T1-E3?
The DG2520DV-T1-E3 supports ±50 mA continuous current on any terminal, as specified in its Absolute Maximum Ratings table. This rating applies across the full operating temperature range (-40 °C to +85 °C) and ensures safe operation under steady-state load conditions without triggering overcurrent protection, which activates only above ~1.7 A.
Does the DG2520DV-T1-E3 support rail-to-rail analog signal switching?
Yes, the DG2520DV-T1-E3 supports full rail-to-rail analog signal switching from 0 V to V+, as confirmed in the "Analog Signal Range" specification (VNO/VNC/VCOM = 0 to V+). This allows undistorted transmission of signals spanning the entire supply range, critical for battery-powered audio and video applications where headroom is constrained.
How does the overcurrent protection circuit behave during a sustained short circuit?
During a sustained short, the DG2520DV-T1-E3's overcurrent protection pulses the switch off for less than 1 µs, then waits 5 ms before attempting reactivation. If the short persists, it repeats this cycle-producing a pulsed output rather than latching off. This behavior is documented in the datasheet's DESCRIPTION section and enables automatic recovery without manual reset.
Is the DG2520DV-T1-E3 pin-compatible with the DG2521DV-T1-E3?
No, the DG2520DV-T1-E3 and DG2521DV-T1-E3 share identical pinouts (TSOP-6, same pin functions), but differ in switching architecture: DG2520 is break-before-make, while DG2521 is make-before-break. Their truth tables and timing parameters (e.g., tbbm vs. tmbb) are mutually exclusive-direct substitution may cause signal shorting or timing violations.
What logic voltage levels are compatible with the IN pin of the DG2520DV-T1-E3?
The IN pin of the DG2520DV-T1-E3 is +1.6 V logic compatible across its full 1.8–5.5 V supply range, meaning it reliably recognizes logic high at ≥1.8 V (V+ = 3 V) or ≥2.4 V (V+ = 5 V), and logic low at ≤0.4 V (V+ = 3 V) or ≤0.8 V (V+ = 5 V). This eliminates need for external level shifters when interfacing with 1.8 V or 3.3 V microcontrollers.
