SZSMF48AT1G Datasheet | Littelfuse

Description The SZSMF series is designed to protect sensitive system or ponents from high voltage, high energy transients. It offers a fast response time, low Zener impedance, high surge capability and excellent clamping capability. Because of its small size, it is ideal for use in cellular phones, portable devices, business machines, power supplies and other industrial / consumer applications. Maximum Ratings and Thermal Characteristics Rating Maximum Ppk Dissipation (PW- 10/1000 µs) (Note 1) SZSMF5.0A - SZSMF58A Symbol PPK Maximum PPK Dissipation @ TA = 25°C, (PW- 8/20 µs) (Note 2) Value 200 1000 Unit W W DC Power Dissipation @ TA = 25°C (Note 3) Derate Above 25°C Thermal Resistance from Junction- to- Ambient (Note 3) 385 m W 4.0 m W/°C RƟJA 325 °C/W Thermal Resistance, Junction-to-Lead (Note3) RƟJL Operating and Storage Temperature Range TJ, Tstg °C/W - 55 to +150 °C Stresses exceeding Maximum Ratings may damage the ponent. Maximum Ratings are stress ratings only. Functional operation above the Remended Operating Conditions is not implied. Extended exposure to stresses above the Remended Operating Conditions may affect ponent reliability. 1. Non- repetitive current pulse at TA = 25°C, per waveform of Figure 2. 2. Non- repetitive current pulse at TA = 25°C, per waveform of Figure 3. 3. Mounted with remended minimum pad size, DC board FR- 4. 4. 1/2 sine wave (or equivalent square wave), PW = 8.3 ms, duty cycle = 4 pulses per minute maximum.
