1 / 3 page Axial-Leaded 1.5 Watt 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 Copyright 2003 10-13-2003 REV B SCOTTSD A L E DIVISION 1N5913BP thru 1N5956BP (Plastic) DESCRIPTION APPEARANCE The 1N5913-5956B series of 1.5 watt Zeners provides voltage regulation in a selection from 3.3 to 200 volts with different tolerances as identified by suffix letter on the part. These plastic encapsulated Zeners have moisture classification of Level 1 with no dry pack required. They are also available in various military screening levels by adding a prefix identifier as described in the Features below. The plastic molded Zeners with a P suffix provide a lower thermal resistance (junction to lead) compared to the optional glass body (G suffix) for these same JEDEC part numbers. Both package options are available by Microsemi. Microsemi also offers numerous other Zener products to meet higher or lower power and test-current applications. DO-41 or DO-204AL (Plastic) IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com FEATURES APPLICATIONS / BENEFITS • JEDEC registered 1N5913 to 1N5956B • Zener voltage available 3.3V to 200V • Standard voltage tolerances are plus/minus 5% with B suffix and 10 % with A suffix identification • Tight tolerances available in plus or minus 2% or 1% with C or D suffix respectively • 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. • Surface mount equivalents available as SMBJ5913 to SMBJ5956B or SMBG5913 to SMBG5956B • Optional glass body axial-leaded Zeners available as 1N5913BG to 1N5956BG (see separate data sheet) • Regulates voltage over a broad operating current and temperature range • Wide selection from 3.3 to 200 V • Flexible axial-lead mounting terminals • Nonsensitive to ESD • Moisture classification is Level 1 per IPC/JEDEC J-STD-020B with no dry pack required • Specified capacitance (see Figure 3) MAXIMUM RATINGS MECHANICAL AND PACKAGING • Power dissipation at 25 ºC: 1.5 watts (also see derating in Figure 1). • Operating and Storage temperature: -65 ºC to +150ºC • Thermal Resistance: 45 ºC/W junction to lead at 3/8 (10 mm) lead length from body, or 105 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: 1.5 watts at TL < 82.5 oC 3/8 inch (10 mm) from body, or 1.19 watts at TA = 25 ºC when mounted on FR4 PC board as described for thermal resistance (also see Figure 1) • Forward voltage @200 mA: 1.2 volts (maximum) • Solder Temperatures: 260 ºC for 10 s (max) • CASE: Void-free transfer molded thermosetting epoxy body meeting UL94V-0 • TERMINALS: Leads, tin-lead plated solderable per MIL-STD-750, method 2026 • POLARITY: Cathode indicated by band.
