Product details
Overview
1N4753E3/TR13 from Microsemi is a 1.0 W axial-lead silicon Zener diode with nominal Zener voltage of 36 V, ±5% tolerance (A-suffix), 7.0 mA test current (IZT), 50 Ω dynamic impedance at IZT, and maximum reverse current of 5 μA at 27.4 V. It regulates voltage in power supply reference and overvoltage protection circuits across industrial temperature range.
For engineers reviewing the 1N4753E3/TR13 datasheet, 1N4753E3/TR13 pinout, 1N4753E3/TR13 application, or 1N4753E3/TR13 equivalent, key selection factors include its DO-41 package thermal resistance (45 °C/W junction-to-lead), 150 °C max operating temperature, RoHS-compliant matte-tin plating, and tape-and-reel packaging (TR13).
Technical Context
This Zener operates in reverse breakdown to maintain stable voltage under varying load and temperature conditions. Its regulation performance is defined by 7.0 mA test current, 50 Ω dynamic impedance at that current, and 0.25 A maximum regulator current at 50 °C ambient.
The device features a sharp knee in the breakdown curve verified by dual-point Zener impedance measurement per MicroNote 202, and exhibits low temperature coefficient typical for 36 V Zeners-approximately +12 mV/°C per Figure 3 in the datasheet.

FAQ
What is the Zener voltage tolerance of 1N4753E3/TR13?
The 1N4753E3/TR13 has a nominal Zener voltage of 36 V with ±5% tolerance, as indicated by the "A" suffix in the part number per Microsemi's JEDEC-registered specification. This tolerance applies at 7.0 mA test current and 25 °C lead temperature, and remains valid across the full –65 °C to +150 °C operating range per the published derating curves.
Does 1N4753E3/TR13 require dry packing before reflow soldering?
No, the 1N4753E3/TR13 is moisture sensitivity level (MSL) Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions without dry pack or baking. Its void-free epoxy body and RoHS-compliant matte-tin plating ensure compatibility with standard 260 °C / 10 s reflow profiles.
What is the maximum surge current rating for 1N4753E3/TR13?
The 1N4753E3/TR13 has a maximum non-repetitive surge current (ISM) of 125 mA, measured using a ½ sine-wave pulse of 1/120 second duration at 25 °C ambient. This rating supports transient overvoltage clamping in industrial power rails where short-duration spikes occur.
Can 1N4753E3/TR13 be used in place of 1N4753A in existing designs?
Yes, the 1N4753E3/TR13 is a direct RoHS-compliant replacement for 1N4753A, sharing identical electrical specifications, DO-41 package dimensions, and thermal characteristics. The only differences are matte-tin plating (vs. Sn/Pb) and EIA-296 tape-and-reel packaging-both fully compatible with legacy footprints and assembly processes.
What is the thermal resistance from junction to ambient for 1N4753E3/TR13 on a standard PCB?
When mounted on a FR4 printed circuit board with 1 oz copper, 4 mm² copper pads, and 1 mm track width (25 mm length), the 1N4753E3/TR13 exhibits a junction-to-ambient thermal resistance of 105 °C/W. This value is critical for calculating safe operating area under continuous 1 W dissipation at elevated ambient temperatures.
