1 / 3 page 1SMB5926 THRU 1SMB5956 SURFACE MOUNT SILICON ZENER DIODE VOLTAGE - 11 TO 200 Volts Power - 1.5 Watts FEATURES l For surface mounted applications in order to optimize board space l Low profile package l Built-in strain relief l Glass passivated junction l Low inductance l Typical IR less than 1 £gA above 11V l High temperature soldering : 260 ¢J /10 seconds at terminals l Plastic package has Underwriters Laboratory Flammability Classification 94V-O MECHANICAL DATA Case: JEDEC DO-214AA Molded plastic over passivated junction Terminals: Solder plated, solderable per MIL-STD-750, method 2026 Polarity: Color band denotes positive end (cathode) Standard Packaging: 12mm tape (EIA-481) Weight: 0.003 ounce, 0.093 gram MAXIMUM RATINGS AND ELECTRICAL CHARACTERISTICS Ratings at 25 ¢J ambient temperature unless otherwise specified. SYMBOL VALUE UNITS DC Power Dissipation @ TL=75 ¢J , Measure at Zero Lead Length(Note 1, Fig. 1) Derate above 75 ¢J PD 1.5 15 Watts mW/¢J Peak forward Surge Current 8.3ms single half sine-wave superimposed on rated load(JEDEC Method) (Note 1,2) IFSM 10 Amps Operating Junction and Storage Temperature Range TJ,TSTG -55 to +150 ¢J NOTES: 1. Mounted on 5.0mm 2(.013mm thick) land areas. 2. Measured on 8.3ms, single half sine-wave or equivalent square wave, duty cycle = 4 pulses per minute maximum. 3. ZENER VOLTAGE (Vz) MEASUREMENT Nominal zener voltage is measured with the device function in thermal equilibrium with ambient temperature at 25 ¢J . 4.ZENER IMPEDANCE (Zz) DERIVATION ZZT and ZZK are measured by dividing the ac voltage drop across the device by the accurrent applied. The specified limits are for IZ(ac) = 0.1 IZ, (dc) with the ac freqency = 60Hz. DO-214AA MODIFIED J-BEND |
