7 / 8 page STK401-060 No. 4680—7/8 Similarly, when STK401-060 VCC = ±23V and RL = 3Ω, from Figure 2: Pd = 38W (for 1/10 PO max = 3.5W) From expression (1) ′: θc-a < (125 − 50)/38 < 1.97 From expression (2) ′: θc-a < (150 − 50)/38 − 1.8/4 < 2.18 Figure 1. Pd — PO Figure 2. Pd — PO THD — PO THD — PO PO — VIN PO — f Therefore, to satisfy both expressions, the required heat- sink must have a thermal resistance less than 1.97 °C/W. This heatsink design example is based on a constant-volt- age supply, and should be verified within your specific set environment. |
