Product details
Overview
1N5361AE3/TR13 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 27 V, ±10% tolerance (A suffix), 50 mA test current (IZT), 5.0 Ω maximum dynamic impedance (ZZ), and 120 mA maximum Zener current (IZM) at 25 °C with adequate heat sinking. It regulates voltage across wide current and temperature ranges (-65 °C to +150 °C) in power supply reference and overvoltage protection circuits.
For engineers reviewing the 1N5361AE3/TR13 datasheet, 1N5361AE3/TR13 pinout, 1N5361AE3/TR13 application, or 1N5361AE3/TR13 equivalent, key selection factors include its 27 V Zener voltage, ±10% tolerance, 5 W steady-state power rating at TL < 25 °C, 25 °C/W junction-to-lead thermal resistance, and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device operates as a voltage reference by maintaining a stable reverse-biased breakdown voltage (VZ = 27 V) across a broad operating current range (10%–50% of IZM). Its low dynamic impedance (5.0 Ω) ensures minimal voltage variation under load changes, while its 25 °C/W thermal resistance enables reliable 5 W dissipation when leads are mounted at 3/8″ (10 mm) from body.
The 1N5361AE3/TR13 is rated for surge currents up to 120 A (8.3 ms half-sine), withstands high transient stresses, and exhibits ≤0.60 V voltage regulation (ΔVZ) between 10% and 50% of IZM. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 27 V ±10% - defines precise DC reference point for feedback loops and clamping thresholds |
| Test Current (IZT) | 50 mA - standardized bias point at which VZ and ZZ are guaranteed |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5361B | Same 27 V VZ, but ±5% tolerance (B suffix) and 50 mA IZT; identical package and thermal specs | Higher precision reference needed where tighter regulation is critical | Select 1N5361B when ±5% VZ tolerance is required; otherwise 1N5361AE3/TR13 offers cost advantage |
| MMBZ5255BS-7-F | Surface-mount SOD-123 package; 27 V VZ, ±5%; 200 mW power rating; not drop-in compatible | PCB space-constrained designs requiring SMT assembly | Choose MMBZ5255BS-7-F only for SMT layouts; 1N5361AE3/TR13 remains optimal for through-hole or high-power (>500 mW) use |
Compared with 1N5361B and MMBZ5255BS-7-F, the 1N5361AE3/TR13 delivers full 5 W dissipation in axial-leaded form with ±10% tolerance - balancing cost, robustness, and thermal performance where board-level mounting flexibility and surge resilience are prioritized over ultra-tight voltage accuracy or miniaturization.

FAQ
What is the Zener voltage tolerance of the 1N5361AE3/TR13?
The 1N5361AE3/TR13 has a Zener voltage tolerance of ±10%, indicated by the "A" suffix in its part number. This means its measured VZ at 50 mA test current falls within 24.3 V to 29.7 V at 25 °C. The e3 suffix confirms RoHS compliance, and TR13 denotes tape-and-reel packaging per EIA-296. This tolerance is suitable for non-critical reference and clamping functions where cost efficiency is prioritized over ultra-precise regulation.
What is the maximum continuous power dissipation for the 1N5361AE3/TR13?
The 1N5361AE3/TR13 is rated for 5.0 W steady-state power dissipation when lead temperature (TL) is maintained below 25 °C - achieved by mounting leads at least 3/8″ (10 mm) from the diode body. On FR4 PCB with 1 oz copper, its derated power drops to 1.47 W at 25 °C ambient due to higher junction-to-ambient thermal resistance (85 °C/W). Full 5 W operation requires external heat sinking or forced-air cooling.
Does the 1N5361AE3/TR13 require dry packing before reflow soldering?
No, the 1N5361AE3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level (MSL) 1, meaning it is not moisture-sensitive and does not require dry packing or baking prior to soldering. Its void-free thermosetting epoxy case (UL94V-0) and matte-tin plating ensure compatibility with standard reflow profiles up to 260 °C for 10 seconds, simplifying manufacturing logistics and reducing process risk.
What is the surge current rating of the 1N5361AE3/TR13?
The 1N5361AE3/TR13 is rated for a non-recurrent peak surge current (IZSM) of 120 A, defined as the maximum amplitude of an 8.3 ms half-sine waveform. This rating reflects its ability to absorb transient overvoltage events - such as ESD or inductive switching spikes - without degradation. Surge capability is enabled by its low thermal resistance (25 °C/W) and robust silicon construction, making it suitable for front-end protection in industrial power systems.
How does the dynamic impedance of the 1N5361AE3/TR13 affect circuit performance?
The 1N5361AE3/TR13 has a maximum dynamic impedance (ZZ) of 5.0 Ω at 50 mA test current, meaning its regulated voltage varies by ≤5 mV per 1 mA change in Zener current. This low ZZ ensures stable reference voltage under varying load conditions - critical in feedback networks and precision clamps. Lower ZZ directly improves regulation accuracy and reduces output ripple in power supply designs using the 1N5361AE3/TR13 as a shunt reference.
