Description
MIC MOSFET IRL3803
Infineon IRL3803 MOSFET alternative equivalent replacement
Brand: MIC
Part Number:MIC-IRL3803
IRL3803. It is basically a N-Channel power Metal Oxide Silicon Field Effect Transistor (MOSFET) and operates in enhancement mode. MOSFET is a lot sensitive in comparison to anFET (Field Effect Transistor) due to its very high input impdence. IRL3803 can perform very fast switching as compared to the normal transistor,Famous brand include Vishay,International Rectifier (IR) , Sanyo.Many end customer are looking for cost effective alternative and replacement solution for IRL3803. MIC brand IRL3803 can be good option.
Following comparison of two type electrical performance:
| Manufacture | MIC Brand | Infineon Brand |
| Part Number | MIC-IRL3803 | IRL3803 |
| Vds max (V) | 30 V | 30 V |
| Id max(A)@25℃ | 140 A | 140 A |
| Rds(on)(m Ohm)@Vgs=10v | 5 mΩ | 6 mΩ |
|
TJ(℃) |
-55 ~ 150℃ | -55 ~ 150℃ |
| Package | TO 220 | TO220 |
Layout:
We can understand from above form,
1) Regarding Vds, or we call it "withstand voltage", MIC brand and Infineon brand in same 30V, that meet the requirement of the typical application like Lithium battery protection circuit 48V, sufficient margin lead to high reliability.
2) Regarding Rds(on), or we call it "dissipation loss", MIC brand Rds(on) offer 5 mΩ, which is little better than Infineon in norminate value.
3) Regarding Id "current value", we see MIC brand and Infineon offer same 140A, in same level.
4) Regarding package, MIC brand and Infineon both offer TO220, with same layout can be pin to pin compatible.
