Product details
Overview
1N5365CE3/TR12 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 36 V, ±2% tolerance (C suffix), 30 mA test current (IZT), 11 Ω dynamic impedance (ZZ), and maximum reverse leakage of 0.5 μA at 28.1 V (VR). 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 1N5365CE3/TR12 datasheet, 1N5365CE3/TR12 pinout, 1N5365CE3/TR12 application, or 1N5365CE3/TR12 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), surge current rating (160 A), voltage regulation (ΔVZ = 3.3 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 across wide current (30 mA IZT to 160 mA IZM) and temperature ranges. Its low dynamic impedance (11 Ω) and tight ±2% voltage tolerance ensure minimal deviation under load variation.
The 1N5365CE3/TR12 uses a void-free thermosetting epoxy T-18 package with cathode band marking, rated for 5 W steady-state dissipation at TL < 25 °C (3/8″ lead length), and exhibits 0.65 V maximum voltage regulation (ΔVZ) between 10% and 50% of IZM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36 V ±2% - precise regulation point for feedback loops and reference circuits |
| Test Current (IZT) | 30 mA - operating point where VZ and ZZ are specified; defines minimum stable bias current |
| Dynamic Impedance (ZZ) | 11 Ω - low AC resistance ensures minimal voltage shift with current transients |
| Max Reverse Leakage (IR) | 0.5 μA @ 28.1 V - negligible standby power loss in high-impedance sensing paths |
| Max Regulator Current (IZM) | 160 mA - maximum continuous DC current before thermal derating begins |
| Surge Current (IZSM) | 160 A (8.3 ms half-sine) - withstands short-duration line surges without failure |
| Voltage Regulation (ΔVZ) | 3.3 V - difference between VZ measured at 10% and 50% of IZM; quantifies regulation linearity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5365B | Same 36 V nominal VZ but ±5% tolerance (B suffix); higher IR (0.5 μA vs. same), identical IZM and ZZ | Acceptable where ±5% regulation accuracy suffices; lower cost in non-critical references | Select 1N5365B if system-level tolerance budget allows wider VZ spread and cost optimization is prioritized |
| MMSZ5245B-TP | Surface-mount SOD-123 package; 36 V ±5%, 10 mA IZT, 17 Ω ZZ, 1 W rating, 200 mA IZM | Used in space-constrained PCBs; requires thermal pad design; unsuitable for 5 W continuous dissipation | Choose MMSZ5245B-TP only for low-power, high-density layouts where 1 W max dissipation is sufficient |
Compared with 1N5365B and MMSZ5245B-TP, the 1N5365CE3/TR12 uniquely delivers ±2% tolerance in a 5 W axial package with proven surge robustness-making it optimal for industrial-grade references requiring long-term stability and field reliability.

FAQ
What is the Zener voltage tolerance of the 1N5365CE3/TR12?
The 1N5365CE3/TR12 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its actual breakdown voltage falls within 35.28 V to 36.72 V at 30 mA test current and 25 °C lead temperature. This tighter tolerance supports high-accuracy applications such as precision feedback networks and calibrated reference sources where ±5% devices would introduce unacceptable error.
Does the 1N5365CE3/TR12 require dry packing for moisture sensitivity?
No, the 1N5365CE3/TR12 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it is not moisture-sensitive and does not require dry packing or baking prior to soldering. Its void-free thermosetting epoxy T-18 package inherently prevents moisture ingress, enabling direct use from tape-and-reel (TR12) packaging without humidity-related reliability concerns.
What is the maximum continuous current the 1N5365CE3/TR12 can handle?
The 1N5365CE3/TR12 supports a maximum continuous Zener current (IZM) of 160 mA when adequately heat sunk-specifically at TL < 25 °C with 3/8″ (10 mm) lead length from the body. At ambient conditions on FR4 board (1 oz Cu, 4 mm² pads), its steady-state power drops to 1.47 W, limiting usable current to approximately 41 mA without forced cooling or thermal enhancement.
How is polarity marked on the 1N5365CE3/TR12?
The 1N5365CE3/TR12 uses a cathode band marking: the banded end is the cathode and must be held positive relative to the anode to operate in Zener breakdown mode. This polarity convention aligns with standard diode marking practice and is critical for correct integration into shunt regulator or clamp circuits-reversal will result in forward conduction (~1.2 V drop) rather than regulation.
Is the 1N5365CE3/TR12 suitable for surge protection applications?
Yes, the 1N5365CE3/TR12 is explicitly rated for 160 A non-recurrent surge current (IZSM) in an 8.3 ms half-sine waveform, making it suitable for IEC 61000-4-5 Level 4 transient suppression. Its robust construction, low thermal resistance (25 °C/W), and stable ΔVZ (3.3 V) ensure predictable clamping behavior during repetitive or single-event surges without parameter drift or catastrophic failure.
