ZDT1048TA from Diodes Incorporated, in a SOT-223-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | B1 | input | Base of NPN transistor Q1. Drive with I_B up to 500 mA; V_BE(on) typ 900 mV at I_C = 5 A, V_CE = 2 V. V_EBO absolute max 5 V. |
| 2 | E1 | passive | Emitter of NPN transistor Q1. Return path for collector current up to I_C(cont) = 5 A (I_CM peak 20 A). Typically tied to the local ground/return in switching applications. |
| 3 | B2 | input | Base of NPN transistor Q2. Drive with I_B up to 500 mA; V_BE(on) typ 900 mV at I_C = 5 A, V_CE = 2 V. V_EBO absolute max 5 V. |
| 4 | E2 | passive | Emitter of NPN transistor Q2. Return path for collector current up to I_C(cont) = 5 A (I_CM peak 20 A). |
| 5 | C2 | passive | Collector of NPN transistor Q2 (doubled with pin 6 for reduced R and improved heat spreading). V_CBO absolute max 50 V, V_CEO 17.5 V, I_C(cont) 5 A. Must be tied to pin 6 externally. |
| 6 | C2 | passive | Collector of NPN transistor Q2 (doubled with pin 5). V_CBO absolute max 50 V, V_CEO 17.5 V, I_C(cont) 5 A. |
| 7 | C1 | passive | Collector of NPN transistor Q1 (doubled with pin 8 for reduced R and improved heat spreading). V_CBO absolute max 50 V, V_CEO 17.5 V, I_C(cont) 5 A. Must be tied to pin 8 externally. |
| 8 | C1 | passive | Collector of NPN transistor Q1 (doubled with pin 7). V_CBO absolute max 50 V, V_CEO 17.5 V, I_C(cont) 5 A. |
