Ukuthetha kwa Sogeki Temparaturu

1. Njelelo Lento ya Msingi

Temperatu rengu wa juku ni siku ya kufanya kazi ya nyenzo ya silikon katika sehemu ya P-N. Ni muhimu kwa uaminifu na utendakazi wa vipengee vya mifumo yasiyo ya mtandaoni.

Thj = Ta + Pd x θja
Thetha ya Jhukumu Tj lisiyabonga nalo Tc nempumulwa na Padi × Unyesi ya Junction, θjc
Pd ndebe yVce × Ic kwa transistor

2. Isikulu Iliyanu Ndiyo

Mngani wa ubora dhaifu wa thabiti:

  • Temperiaturi ya Velezi Tj
  • Umzambo wa Hlala Ta
  • Temperatu re ya Kesi Ts
  • Isiduko yafupi ya Engeleko Pd
  • Thetha-jukti-ihlambo-ithembu kwenkoshiphalo θja
  • Isithetha kwenza-kasuku Izimbizo Lethemba θjc

Ukujengwa kuhusu Ushirikisho wa Habari ya Taifa

Fikilima kwa ukosefu wa ushiriki wa joto na hesabu:

θya = Ta - Tj / Pd
Ukuthetha wa θjc = Temperatures ya Tj ukwa Themperatures ya Tc / Ukayayo wa Pd.

What is Junction Temperature?

Junction temperature is the operating temperature at the semiconductor p-n junction. It's a critical parameter that affects device reliability, performance and lifespan.

How to Calculate Junction Temperature?

Junction temperature can be calculated using:

  • Tj = Ta + (Pd × θja) for ambient reference
  • Tj = Tc + (Pd × θjc) for case reference
  • Consider power dissipation (Pd)
  • Account for thermal resistance (θ)

What is a Good Junction Temperature for GPU?

For GPUs, recommended junction temperatures are:

  • Normal operation: 65-85°C
  • Maximum safe: 95-105°C
  • Throttling point: 110°C
  • Memory junction: <95°C
