Product details
Overview
1N5359CE3/TR13 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 24 V, ±2% tolerance (C suffix), 3.5 Ω dynamic impedance at 50 mA test current, and maximum reverse leakage of 0.5 µA at 19.4 V. 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 1N5359CE3/TR13 datasheet, 1N5359CE3/TR13 pinout, 1N5359CE3/TR13 application, or 1N5359CE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), surge current rating (100 A), voltage regulation (ΔVZ = 0.55 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 10–50 mA operating current. Its low dynamic impedance (3.5 Ω) and tight ±2% VZ tolerance ensure minimal voltage drift under load variation and temperature cycling.
The 1N5359CE3/TR13 uses void-free thermosetting epoxy encapsulation (UL94V-0), cathode band polarity marking, and is rated for 260 °C soldering (10 s). Thermal performance is specified at 3/8″ (10 mm) lead length from body (25 °C/W) or on FR4 PCB (85 °C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 24 V ±2% - precise regulation point for feedback loops and reference circuits |
| Test Current (IZT) | 50 mA - standardized bias point for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZ) | 3.5 Ω - low AC resistance ensures stable voltage under varying load currents |
| Max Reverse Leakage (IR) | 0.5 µA @ 19.4 V - negligible standby current in high-impedance sensing applications |
| Power Dissipation (PD) | 5.0 W @ TL = 25 °C - requires heat sinking above ambient for full-power operation |
| Surge Current (IZSM) | 100 A (8.3 ms half-sine) - withstands transient overvoltage events without failure |
| Voltage Regulation (ΔVZ) | 0.55 V - difference between VZ measured at 10% and 50% of IZM, indicating regulation linearity |
Pinout & Package
Package: Axial-leaded T-18 plastic case (void-free UL94V-0 epoxy), cathode indicated by color band. Leads are annealed matte-tin plated (RoHS compliant, solderable per MIL-STD-750 Method 2026). Weight: 0.7 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to circuit ground or lower-potential node; reverse bias applied across anode–cathode |
| Cathode | Zener regulation terminal / voltage reference output | Banded end; connected to regulated voltage node; defines VZ relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| ±2% Zener voltage tolerance (C suffix) | Enables high-accuracy voltage references without post-calibration in industrial control systems |
| 25 °C/W junction-to-lead thermal resistance | Supports reliable 5 W operation with simple lead-length heat sinking (3/8″ from body) |
| Moisture sensitivity Level 1 (IPC/JEDEC J-STD-020B) | Eliminates dry-pack requirement and bake-out prior to assembly |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Reduces handling precautions and eliminates ESD protection circuitry in board design |
| e3 RoHS-compliant plating | Meets global environmental compliance without sacrificing solderability or reliability |
Applications

Use Value: Tight ±2% initial tolerance and low thermal resistance (25 °C/W) reduce temperature-induced calibration drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5359B | Same 24 V nominal VZ, but ±5% tolerance (B suffix) and higher ZZ (3.5 Ω vs. 3.5 Ω - identical per datasheet; however B has looser tolerance) | Acceptable where ±5% regulation accuracy suffices and cost is prioritized over precision | Select 1N5359B only if system-level tolerance budget allows ±5% VZ variation without recalibration. |
| MMBZ5242B (SOT-23) | 24 V ±5%, 0.5 W rating, surface-mount package, 100 Ω ZZ at 20 mA | Suitable for space-constrained PCBs but cannot sustain 5 W continuous dissipation | Choose MMBZ5242B only for low-power signal-level clamping; 1N5359CE3/TR13 remains required for 5 W regulation duty. |
Compared with 1N5359B and MMBZ5242B, the 1N5359CE3/TR13 uniquely delivers ±2% tolerance, 5 W power handling, and axial-leaded mechanical robustness-making it irreplaceable in high-reliability industrial power regulation where precision and thermal resilience are jointly critical.

FAQ
What is the Zener voltage tolerance of the 1N5359CE3/TR13?
The 1N5359CE3/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its nominal 24 V regulation point falls within 23.52 V to 24.48 V at 50 mA test current and 25 °C lead temperature. This tighter tolerance supports applications demanding higher reference accuracy than the standard ±5% (B suffix) or ±10% (A suffix) variants.
Can the 1N5359CE3/TR13 be used in surface-mount designs?
No, the 1N5359CE3/TR13 is an axial-leaded T-18 package and is not compatible with surface-mount assembly. For SMT equivalents, Microsemi offers the SMBJ5359B (DO-214AA) and SMBG5359B (DO-214AB) series, but these differ in package, thermal performance, and mounting requirements. The 1N5359CE3/TR13 must be mounted through-hole with appropriate lead-forming and heat sinking.
What is the maximum steady-state power dissipation for the 1N5359CE3/TR13 on a standard PCB?
When mounted on a standard FR4 PCB (1 oz copper, 4 mm² pads, 1 mm track width, 25 mm length), the 1N5359CE3/TR13 has a steady-state power rating of 1.47 W at 25 °C ambient temperature. This derates linearly above 25 °C per the 85 °C/W junction-to-ambient thermal resistance. Full 5 W operation requires lead-length heat sinking per the 25 °C/W junction-to-lead specification.
Does the 1N5359CE3/TR13 require dry packing before reflow soldering?
No, the 1N5359CE3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it is not hygroscopic and does not require dry packing or baking prior to soldering. Its void-free thermosetting epoxy body inherently resists moisture absorption, simplifying manufacturing logistics and eliminating pre-reflow bake steps.
How is polarity identified on the 1N5359CE3/TR13?
The cathode of the 1N5359CE3/TR13 is marked by a distinct color band on the body. The diode must be operated with the banded end held at a more positive potential than the unmarked (anode) end to achieve Zener breakdown and regulation. Reversing polarity subjects it to forward conduction (VF ≤ 1.2 V @ 1 A), not regulation.
