1 / 3 page 500 mW GLASS AXIAL-LEAD ZENER DIODES Microsemi Scottsdale Division 8700 E. Thomas Rd. PO Box 1390, Scottsdale, AZ 85252 USA, (480) 941-6300, Fax: (480) 947-1503 Page 1 S C O T TS DALE DIVISION 1N5221 thru 1N5281B, e3 DO-35 DESCRIPTION APPEARANCE The popular 1N5221 thru 1N5281B series of 0.5 watt Zener Voltage Regulators provides a selection from 2.4 to 200 volts in standard 5% or 10% tolerances as well as tighter tolerances identified by different suffix letters on the part number. These glass axial-leaded DO-35 Zeners are also available in various military screening levels by adding a prefix identifier as described in the Features section. Microsemi also offers numerous other Zener products to meet higher and lower power applications. IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com FEATURES APPLICATIONS / BENEFITS • JEDEC registered 1N5221 to 1N5281B • Internal bonds optionally available with “-1” suffix • Options for screening in accordance with MIL-PRF- 19500 for JAN, JANTX, JANTXV, and JANS are available by adding MQ, MX, MV, or MSP prefixes respectively to part numbers with “-1” suffix. • Surface mount equivalents available as MLL5221 to MLL5281B in the DO-213AA MELF style package including “-1” suffix options (consult factory for others) • RoHS Compliant devices available by adding “e3” suffix • DO-7 glass body axial-leaded Zener equivalents are also available • Regulates voltage over a broad operating current and temperature range • Extensive selection from 2.4 to 200 V • Standard voltage tolerances are plus/minus 5% with B suffix, 10 % with A suffix identification • Tight tolerances available in plus or minus 2% or 1% with C or D suffix respectively • Flexible axial-lead mounting terminals • Nonsensitive to ESD (MIL-STD-750 Method 1020) • Minimal capacitance (see Figure 2) • Inherently radiation hard per MicroNote 050 MAXIMUM RATINGS MECHANICAL AND PACKAGING • Power dissipation at 25ºC: 0.5 watts (also see derating in Figure 1). • Operating and Storage temperature: -65ºC to +175ºC • Thermal Resistance: 250 ºC/W junction to lead at 3/8 (10 mm) lead length from body, or 310 ºC/W junction to ambient when mounted on FR4 PC board (1 oz Cu) with 4 mm 2 copper pads and track width 1 mm, length 25 mm • Steady-State Power: 0.5 watts at T L < 50 oC 3/8 inch (10 mm) from body or 0.48 W at TA < 25 ºC when mounted on FR4 PC board as described for thermal resistance above (also see Figure1) • Forward voltage @200 mA: 1.5 volts (maximum) • Solder Temperatures: 260 ºC for 10 s (max) • CASE: Hermetically sealed axial-lead glass DO- 35 (DO-204AH) package • FINISH: Tin-Lead or RoHS Compliant annealed matte-Tin plating solderable per MIL-STD-750, method 2026 • POLARITY: Cathode indicated by band.
