**Characteristics** 

**STPS10L40C** 

## **1 Characteristics** 

**Table 2: Absolute ratings (limiting values, per diode, at 25 °C, unless otherwise specified)** 

|**Symbol**|**Parameter**|**Parameter**||**Value**|**Unit**|
|---|---|---|---|---|---|
|VRRM|Repetitivepeak reverse voltage|||40|V|
|IF(RMS)|Forward rms current|||20|A|
|IF(AV)|Average forward current δ = 0.5,<br>square wave|TC= 140 °C|Per diode|5|A|
||||Per device|10||
|IFSM|Surge non repetitive forward current|tp= 10 ms sinusoidal||150|A|
|PARM|Repetitivepeak avalanchepower|tp= 10µs, Tj= 125 °C||190|W|
|Tstg|Storage temperature range|||-65 to +150|°C|
|Tj|Maximum operating junction temperature_(1)_|||+150|°C|



## **Notes:** 

(1)(dPtot/dTj) < (1/Rth(j-a)) condition to avoid thermal runaway for a diode on its own heatsink. 

**Table 3: Thermal parameters** 

|**Symbol**|**Parameter**||**Value**|**Unit**|
|---|---|---|---|---|
|Rth(j-c)|Junction to case|Per diode|3.0|°C/W|
|||Total|1.7||
|Rth(c)|Coupling|-|0.35|°C/W|



When the diodes 1 and 2 are used simultaneously: 

ΔTj (diode1) = P(diode1) x Rth(j-c) (per diode) + P(diode2) x Rth(c) 

**Table 4: Static electrical characteristics (per diode)** 

|**Symbol**|**Parameter**|**Test conditions**|**Test conditions**|**Min.**|**Typ.**|**Max.**|**Unit**|
|---|---|---|---|---|---|---|---|
|IR_(1)_|Reverse leakage current|Tj= 25 °C|VR= VRRM|-||0.2|mA|
|||Tj= 100 °C||-|8|25|mA|
|VF_(1)_|Forward voltage drop|Tj= 25 °C|IF= 5 A|-||0.53|V|
|||Tj= 100 °C|IF= 5 A|-|0.36|0.46||
|||Tj= 25 °C|IF= 10 A|-||0.67||
|||Tj= 125 °C|IF= 10 A|-|0.49|0.59||



## **Notes:** 

(1)Pulse test: tp = 380 µs, δ < 2% 

To evaluate the conduction losses use the following equation: 

P = 0.33 x IF(AV) + 0.026 IF[2] (RMS)
