Product details
Overview
1N5362CE3/TR13 from Microsemi is a 5 W axial-leaded silicon Zener diode with a nominal regulation voltage of 28 V, ±2% tolerance (C suffix), 6.0 Ω maximum dynamic impedance at 50 mA test current, and 130 A peak surge current rating. It operates from –65 °C to +150 °C and is used for precision voltage reference and overvoltage protection in industrial power supplies.
For engineers reviewing the 1N5362CE3/TR13 datasheet, 1N5362CE3/TR13 pinout, 1N5362CE3/TR13 application, or 1N5362CE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), steady-state power derating, reverse leakage at VR = 21.2 V, and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device functions as a two-terminal voltage regulator in reverse-biased mode, maintaining stable output voltage across wide current variation (IZM = 130 mA at TL = 25 °C). Its low dynamic impedance (6.0 Ω) and tight ±2% VZ tolerance ensure minimal voltage drift under load changes.
The 1N5362CE3/TR13 uses void-free thermosetting epoxy encapsulation (UL94V-0), cathode band polarity marking, and is rated for 260 °C soldering (10 s max). It meets moisture sensitivity Level 1 per J-STD-020B and supports tape-and-reel packaging (TR13 suffix).
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Test Current (IZT) | 50 mA - standardized bias condition for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZ) | 6.0 Ω max at IZT - low AC resistance ensures stable voltage under varying load currents |
| Max Reverse Leakage (IR) | 0.5 μA at VR = 21.2 V - negligible standby current in high-impedance sensing applications |
| Max Regulator Current (IZM) | 130 mA at TL = 25 °C - defines safe DC operating limit with adequate heat sinking |
| Surge Current (IZSM) | 130 A (8.3 ms half-sine) - withstands transient overvoltage events without failure |
| Voltage Regulation (ΔVZ) | 3.9 V - difference between VZ measured at 10% and 50% of IZM, indicating line regulation performance |

FAQ
What is the Zener voltage tolerance of the 1N5362CE3/TR13?
The 1N5362CE3/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its regulated voltage falls within 27.44 V to 28.56 V at 50 mA test current and 25 °C lead temperature. The tighter tolerance enables use in precision feedback networks without additional trimming components, distinguishing it from ±5% (B suffix) or ±10% (A suffix) variants in the same family.
How does the 1N5362CE3/TR13 handle thermal dissipation?
The 1N5362CE3/TR13 achieves 5 W steady-state power dissipation at 25 °C lead temperature (TL) with 3/8″ (10 mm) lead length from the body, thanks to its 25 °C/W junction-to-lead thermal resistance. When mounted on FR4 with 1 oz copper, its thermal resistance rises to 85 °C/W, limiting usable power to 1.47 W at 25 °C ambient. Derating curves in the official datasheet define safe operating limits above 25 °C.
Is the 1N5362CE3/TR13 RoHS compliant?
Yes, the 1N5362CE3/TR13 is RoHS compliant, confirmed by the "e3" suffix in its part number. It features annealed matte-tin plated leads and void-free UL94V-0 epoxy encapsulation, meeting EU Directive 2011/65/EU requirements. Lead finish and material composition are verified per MIL-STD-750 Method 2026, and no exemptions apply to its construction.
What is the maximum reverse leakage current for the 1N5362CE3/TR13?
The 1N5362CE3/TR13 specifies a maximum reverse leakage current (IR) of 0.5 μA at a reverse test voltage (VR) of 21.2 V. This low leakage ensures minimal parasitic loading in high-impedance reference circuits and preserves accuracy in battery-powered or low-quiescent-current designs where standby current must be tightly controlled.
Can the 1N5362CE3/TR13 be used as a direct replacement for the 1N5362B?
The 1N5362CE3/TR13 shares identical Zener voltage (28 V), package (T-18 axial), and electrical ratings with the 1N5362B, differing only in tighter ±2% tolerance (vs ±5%) and RoHS-compliant e3 marking. It is functionally compatible in all circuits designed for the 1N5362B, though layout and thermal design should verify adequacy for the higher precision and same power dissipation profile of the 1N5362CE3/TR13.
