Product details
Overview
1N5365CE3/TR13 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, 11 Ω dynamic impedance at IZT, and maximum reverse leakage of 0.5 μA at 27.4 V. It serves as a precision voltage reference or shunt regulator in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the 1N5365CE3/TR13 datasheet, 1N5365CE3/TR13 pinout, 1N5365CE3/TR13 application, or 1N5365CE3/TR13 equivalent, key selection criteria include its tight ±2% VZ tolerance, low 11 Ω Zener impedance at 30 mA, 3.3 V voltage regulation (ΔVZ) across 10–50% IZM, RoHS-compliant e3 marking, and tape-and-reel TR13 packaging for automated assembly.
Technical Context
This device operates as a two-terminal shunt regulator, maintaining stable output voltage by conducting reverse current above its specified Zener breakdown threshold. Its thermal resistance is 25 °C/W junction-to-lead (at 10 mm lead length) and 85 °C/W junction-to-ambient on FR4 board - requiring attention to heatsinking at high DC currents.
The 1N5365CE3/TR13 exhibits minimal voltage drift versus current due to low dynamic impedance and tight tolerance, enabling use in precision references where stability across temperature and load is critical. Its cathode band polarity and 1.2 V forward voltage max at 1 A support unambiguous PCB layout and bidirectional surge handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36 V ±2% - ensures accurate regulation within ±0.72 V at 25 °C, suitable for 3.3 V or 5 V LDO feedback or 24 V rail clamping. |
| Test Current (IZT) | 30 mA - defines operating point for VZ measurement and optimal impedance performance. |
| Dynamic Impedance (ZZ) | 11 Ω at IZT - low AC resistance minimizes output voltage variation under changing load current. |
| Max Reverse Leakage (IR) | 0.5 μA at 27.4 V - confirms sharp knee and low standby power loss in high-impedance bias networks. |
| Power Dissipation (PD) | 5.0 W at TL = 25 °C - supports continuous regulation up to ~139 mA at 36 V with adequate lead heatsinking. |
| Voltage Regulation (ΔVZ) | 3.3 V - difference between VZ measured at 10% and 50% of IZM, indicating line regulation capability under varying current. |
| Surge Current (IZSM) | 160 A (8.3 ms half-sine) - enables transient overvoltage suppression without failure in industrial surge environments. |
Pinout & Package
Package: Axial-leaded T-18 plastic case per JEDEC DO-204AL; void-free UL94V-0 epoxy body; matte-tin RoHS-compliant leads; cathode indicated by color band; weight 0.7 g.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5365B | Same 36 V nominal VZ, but ±5% tolerance (B suffix) and no e3 RoHS marking. | Acceptable where ±5% regulation accuracy suffices and lead-free compliance is not required. | Select 1N5365B only if cost sensitivity outweighs tolerance and RoHS needs; not drop-in for 1N5365CE3/TR13 in certified designs. |
| MMSZ5245B-TP | Surface-mount SOD-123 package, 33 V VZ, ±5%, 500 mW rating - lower power and different voltage. | Suitable for space-constrained PCBs but requires redesign for thermal management and voltage scaling. | Choose MMSZ5245B-TP only for low-power, compact layouts where 33 V regulation and 0.5 W dissipation are acceptable. |
Compared with 1N5365B and MMSZ5245B-TP, the 1N5365CE3/TR13 delivers superior voltage accuracy (±2% vs ±5%), higher power handling (5 W vs 0.5 W), and guaranteed RoHS compliance - making it optimal for industrial power supplies requiring long-term stability and regulatory conformance.

FAQ
What is the Zener voltage tolerance of the 1N5365CE3/TR13?
The 1N5365CE3/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its nominal 36 V regulation voltage falls within 35.28 V to 36.72 V at 25 °C and 30 mA test current, enabling high-accuracy voltage referencing without trimming.
Does the 1N5365CE3/TR13 require dry-pack handling per J-STD-020?
No, the 1N5365CE3/TR13 has IPC/JEDEC moisture sensitivity Level 1 classification, meaning it does not absorb significant moisture during ambient storage and requires no dry-packaging or baking prior to reflow soldering - simplifying manufacturing logistics.
What is the maximum steady-state power dissipation for the 1N5365CE3/TR13 on a standard FR4 PCB?
When mounted on an FR4 PCB with 1 oz copper, 4 mm² pads, and 1 mm × 25 mm traces, the 1N5365CE3/TR13 has a steady-state power rating of 1.47 W at 25 °C ambient. Derating applies above 25 °C per the published thermal resistance of 85 °C/W junction-to-ambient.
How is polarity marked on the 1N5365CE3/TR13?
The 1N5365CE3/TR13 uses a cathode band to indicate polarity: the banded end is the cathode and must be held at a higher potential than the anode during Zener operation. This marking aligns with JEDEC DO-204AL standards and ensures correct orientation in shunt regulator configurations.
What does the "TR13" suffix indicate in 1N5365CE3/TR13?
The "TR13" suffix indicates tape-and-reel packaging per EIA-296 standard, with 13-inch reels. This format supports automated surface-mount assembly equipment and is distinct from bulk or ammo-pack options - confirming compatibility with high-volume SMT lines.
