Product details
Overview
1N5364AE3/TR8 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 33 V, ±10% tolerance (A suffix), 40 mA test current, 10 Ω maximum dynamic impedance at IZT, and 150 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 1N5364AE3/TR8 datasheet, 1N5364AE3/TR8 pinout, 1N5364AE3/TR8 application, or 1N5364AE3/TR8 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), surge current rating (150 A), reverse leakage (≤0.5 μA at 26.4 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, with Zener voltage specified at 40 mA test current and measured at 25 °C lead temperature. Its low dynamic impedance (10 Ω) ensures stable regulation under varying load currents, and its 25 °C/W junction-to-lead thermal resistance enables reliable 5 W dissipation with minimal heatsinking at TL < 25 °C.
The 1N5364AE3/TR8 features a T-18 axial package with cathode band marking, UL94V-0 void-free epoxy body, and RoHS-compliant annealed matte-tin leads solderable per MIL-STD-750 Method 2026. It withstands 8.3 ms half-sine surge currents up to 150 A and exhibits ≤0.5 μA reverse leakage at 26.4 V (90% of VZ).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 33 V ±10% - defines nominal regulation point; high-end tolerance = 36.3 V for IZM calculation |
| Test Current (IZT) | 40 mA - standardized bias condition for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZ) | 10 Ω max - low AC resistance ensures minimal voltage shift under load transients |
| Max Zener Current (IZM) | 150 mA - maximum continuous DC current at TL = 25 °C with 3/8″ lead length |
| Reverse Leakage (IR) | ≤0.5 μA at VR = 26.4 V - guarantees low standby power loss in high-impedance bias networks |
| Thermal Resistance (RθJL) | 25 °C/W - enables 5 W operation with only 125 °C junction rise above lead temperature |
| Surge Current (IZSM) | 150 A (8.3 ms half-sine) - supports transient overvoltage clamping without failure |
Pinout & Package
Package: T-18 axial-leaded plastic encapsulated case (UL94V-0 epoxy), cathode indicated by colored band; leads are RoHS-compliant annealed matte-tin, solderable per MIL-STD-750 Method 2026.

Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered Zener family | Ensures industry-standard mechanical dimensions, marking, and reliability testing compliance |
| Moisture sensitivity Level 1 | No dry pack required - simplifies handling and eliminates bake-out prior to assembly |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Eliminates need for special ESD handling protocols during board assembly and test |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5364B | ±5% VZ tolerance (vs. ±10% for 1N5364AE3/TR8); otherwise identical electrical specs and package | Higher precision needed for tighter feedback loops or calibration references | Select 1N5364B when regulation stability within ±1.65 V is required; same thermal and surge performance |
| MMBZ5263BS-7-F | Surface-mount SOD-123 package; 33 V ±5%, 200 mW rating (vs. 5 W axial); different thermal profile | Space-constrained PCBs where axial leads are impractical; not suitable for high-power dissipation | Choose MMBZ5263BS-7-F only for low-current biasing (<5 mA); cannot replace 1N5364AE3/TR8 in 5 W applications |
Compared with 1N5364B and MMBZ5263BS-7-F, the 1N5364AE3/TR8 uniquely balances cost-effective axial mounting, full 5 W capability, and RoHS compliance-making it optimal for industrial power rails requiring robust, through-hole Zener regulation without precision-grade tolerance.

FAQ
What is the Zener voltage tolerance of the 1N5364AE3/TR8?
The 1N5364AE3/TR8 has a Zener voltage tolerance of ±10%, as indicated by the "A" suffix in its part number. This means its nominal 33 V regulation point falls between 29.7 V and 36.3 V at 40 mA test current and 25 °C lead temperature. The tolerance directly affects design margins in feedback networks and overvoltage thresholds.
Can the 1N5364AE3/TR8 be used without a heatsink?
Yes-the 1N5364AE3/TR8 can dissipate its full 5 W rating without an external heatsink when lead temperature (TL) is maintained below 25 °C, achieved via 3/8″ (10 mm) lead length from the body. Its 25 °C/W junction-to-lead thermal resistance allows safe operation at rated power with minimal copper pour, unlike FR4-board-mounted configurations limited to 1.47 W.
What does the "e3" and "TR8" suffix mean in 1N5364AE3/TR8?
The "e3" suffix indicates RoHS compliance with annealed matte-tin lead plating per MIL-STD-750 Method 2026. The "TR8" denotes tape-and-reel packaging per EIA-296 standard, optimized for automated SMT placement. Together, they confirm environmental compliance and assembly readiness-both critical for industrial manufacturing.
How does the 1N5364AE3/TR8 handle surge events?
The 1N5364AE3/TR8 is rated for 150 A peak non-recurrent surge current (IZSM) in an 8.3 ms half-sine waveform. This capability enables reliable clamping of inductive kickback and lightning-induced transients in 24–48 V systems. Its robust T-18 package and low dynamic impedance ensure consistent clamping voltage during surge conduction.
Is the 1N5364AE3/TR8 suitable for precision reference applications?
The 1N5364AE3/TR8 is not intended for high-precision references due to its ±10% Zener voltage tolerance and 10 Ω dynamic impedance. For such use cases, consider the 1N5364B (±5%) or dedicated reference ICs. However, the 1N5364AE3/TR8 delivers sufficient stability for industrial power supply feedback, overvoltage protection, and general-purpose voltage limiting where ±10% is acceptable.
