Product details
Overview
1N5361CE3/TR13 from Microsemi is a 5 W axial-leaded silicon Zener diode with a nominal regulation voltage of 27 V, ±2% tolerance (C suffix), 50 mA test current (IZT), 5 Ω maximum dynamic impedance (ZZ), and 120 mA maximum Zener current (IZM) when adequately heat-sunk. It operates across –65 °C to +150 °C and is used for precision voltage reference and overvoltage protection in industrial power supplies.
For engineers reviewing the 1N5361CE3/TR13 datasheet, 1N5361CE3/TR13 pinout, 1N5361CE3/TR13 application, or 1N5361CE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), surge current rating (120 A), voltage regulation (ΔVZ = 0.60 V), and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device functions as a two-terminal voltage regulator operating in reverse breakdown, maintaining stable output voltage under varying load and temperature conditions. Its low dynamic impedance (5 Ω) and tight ±2% voltage tolerance ensure minimal deviation across its specified 10–50% IZM current range.
The 1N5361CE3/TR13 uses a void-free thermosetting epoxy T-18 package with cathode band polarity marking and is rated for 260 °C soldering (10 s). It meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity and is nonsensitive to ESD per MIL-STD-750 Method 1020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 27 V ±2% - precise regulation point at 50 mA test current, enabling stable reference in feedback loops. |
| Power Dissipation | 5.0 W at 25 °C lead temperature - requires 3/8″ (10 mm) lead length from body for full rating. |
| Dynamic Impedance (ZZ) | 5 Ω max - ensures low voltage variation under changing load currents. |
| Max Zener Current (IZM) | 120 mA - maximum continuous DC current before thermal runaway, assuming adequate heatsinking. |
| Surge Current (IZSM) | 120 A peak - withstands non-repetitive 8.3 ms half-sine transients, suitable for transient suppression. |
| Voltage Regulation (ΔVZ) | 0.60 V - difference between VZ measured at 10% and 50% of IZM, indicating regulation linearity. |
| Thermal Resistance | 25 °C/W junction-to-lead - enables predictable thermal design with standard lead-mounting practices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5361B | Same 27 V nominal VZ, but ±5% tolerance (B suffix) and higher ZZ (5 Ω vs. 5 Ω - identical per spec table) | Acceptable where tighter tolerance not required; lower cost in high-volume industrial controls | Select 1N5361B if system-level calibration compensates for initial tolerance; choose 1N5361CE3/TR13 for factory-set accuracy. |
| MMSZ5259ET1G | Surface-mount SOD-123 package, 27 V ±5%, 500 mW rating, 30 Ω ZZ - significantly lower power and higher impedance | Limited to low-current bias/reference roles; unsuitable for >100 mA regulation or surge suppression | Use MMSZ5259ET1G only in space-constrained PCBs with <50 mA Zener current; retain 1N5361CE3/TR13 for 5 W thermal performance. |
Compared with 1N5361B and MMSZ5259ET1G, the 1N5361CE3/TR13 uniquely delivers ±2% tolerance at 5 W dissipation in an axial-leaded package-enabling high-accuracy, high-power regulation where surface-mount alternatives lack thermal headroom and tighter-tolerance variants are unavailable.

FAQ
What is the Zener voltage tolerance of the 1N5361CE3/TR13?
The 1N5361CE3/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its actual regulation voltage falls between 26.46 V and 27.54 V at 50 mA test current and 25 °C lead temperature, supporting high-accuracy reference designs without post-manufacturing adjustment.
Does the 1N5361CE3/TR13 require dry packing before PCB assembly?
No, the 1N5361CE3/TR13 has IPC/JEDEC J-STD-020B Level 1 moisture sensitivity, meaning it may be stored and assembled without dry packing or baking. Its void-free epoxy T-18 package inherently prevents moisture ingress, eliminating pre-reflow bake cycles and reducing manufacturing risk.
What is the maximum steady-state power dissipation for the 1N5361CE3/TR13 on a standard FR4 PCB?
When mounted on a standard FR4 PCB (1 oz Cu, 4 mm² copper pads, 1 mm track width, 25 mm length), the 1N5361CE3/TR13 is rated for 1.47 W steady-state power dissipation at 25 °C ambient temperature. Full 5 W operation requires 3/8″ (10 mm) lead length from the body for junction-to-lead thermal path optimization.
How does the 1N5361CE3/TR13 handle transient overvoltage events?
The 1N5361CE3/TR13 supports a peak non-repetitive surge current (IZSM) of 120 A for an 8.3 ms half-sine waveform. This capability allows it to absorb common AC-line transients and inductive switching spikes without degradation, making it suitable for primary-side clamping in offline power supplies.
Is the 1N5361CE3/TR13 RoHS compliant?
Yes, the "e3" suffix in 1N5361CE3/TR13 explicitly indicates RoHS compliance. The device features annealed matte-tin plating on leads, fully satisfying EU Directive 2011/65/EU and related global environmental regulations without lead or other restricted substances.
