概述

Description

The SI2315BDS-T1-E3 is a Vishay Siliconix N‑channel enhancement MOSFET. It’s a compact, surface‑mount power switch designed for low‑voltage switching in portable and compact electronics.
Key points:
- Type: N‑channel MOSFET (enhancement mode)
- Typical use: switching/regulating loads in power-management circuits (DC‑DC converters, load switches, battery management)
- Packaging: small SMD package suitable for dense layouts (RoHS/Pb‑free)
- Gate drive: logic‑level capable, enabling operation from 3.3V/5V logic rails
- Electricals (datasheet needed for exact figures): Vds rating in the ~20–30V range; low Rds(on) to minimize conduction losses; gate threshold in the low V range
- Advantages: small footprint, good efficiency, suitable for compact designs
Note: Exact parameters (Vds, Id, Rds(on), package details) vary by lot and variant. Refer to the official datasheet for precise electrical specs, thermal limits, and recommended PCB/layout guidelines.

Features

SI2315BDS-T1-E3 is a small N-channel enhancement-mode MOSFET. Key features (highlights):
- N-channel MOSFET, logic-level gate
- VDS ~ 20 V (max)
- ID handling of several amps (typical ≈ 5 A range)
- Very low RDS(on) at VGS = 4.5 V (typical tens of milliohms)
- Low gate drive required; VGS(th) ≈ 0.7–1.5 V
- Fast switching with low gate charge
- RoHS-compliant Pb-free package in 3-pin SOT-23 (T1) form factor
- Suitable for power switching, DC-DC converters, load switching
Note: exact electrical values (VDS, ID, RDS(on), Qg) vary by lot; consult the datasheet for precise numbers.
