Product details
Overview
1N5364BE3/TR12 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 33 V, ±5% tolerance (B suffix), 10 Ω maximum dynamic impedance at 40 mA test current, and 150 mA maximum Zener current when adequately heat-sunk. It regulates voltage across wide current and temperature ranges in power supply reference and overvoltage protection circuits.
For engineers reviewing the 1N5364BE3/TR12 datasheet, 1N5364BE3/TR12 pinout, 1N5364BE3/TR12 application, or 1N5364BE3/TR12 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (25 °C/W junction-to-lead), surge current rating (150 A), reverse leakage performance at 25.1 V, 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 across its cathode–anode terminals. Its 33 V nominal Zener voltage is specified at 40 mA test current (IZT), with 10 Ω dynamic impedance (ZZ) measured at 1 kHz with 10% AC modulation superimposed on IZT.
Thermal design relies on junction-to-lead thermal resistance of 25 °C/W at 10 mm lead length, enabling 5 W dissipation at 25 °C lead temperature. At ambient mounting on FR4 (1 oz Cu, 4 mm² pad), steady-state power drops to 1.47 W due to higher 85 °C/W junction-to-ambient resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 33 V nominal, ±5% tolerance - defines precise regulation point for feedback loops and reference rails |
| Test Current (IZT) | 40 mA - operating point where VZ and dynamic impedance are guaranteed |
| Dynamic Impedance (ZZ) | 10 Ω max at IZT - determines output voltage stability under load current variation |
| Max Reverse Leakage (IR) | 0.5 μA at 25.1 V - ensures minimal quiescent current in high-impedance bias networks |
| Max Zener Current (IZM) | 150 mA - maximum continuous DC current before exceeding 5 W power limit at TL = 25 °C |
| Surge Current (IZSM) | 150 A peak (8.3 ms half-sine) - supports transient overvoltage clamping without failure |
| Voltage Regulation (ΔVZ) | 3.5 V max - difference between VZ measured at 15 mA and 75 mA, indicating line regulation capability |
Pinout & Package
Package: T-18 axial-leaded plastic case (Void-free transfer-molded thermosetting epoxy, UL94V-0 rated), 0.7 g weight, cathode indicated by band. Leads are RoHS-compliant annealed matte-tin plated, solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Regulated output node | Connected to positive side of regulated rail; reverse-biased operation requires this terminal to be at higher potential than anode |
| Anode (unbanded end) | Reference/return node | Typically tied to system ground or lower-potential rail; completes current path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered Zener family | Ensures standardized mechanical dimensions, marking, and electrical behavior across global supply chain |
| 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 testing |
| RoHS-compliant (e3 suffix) | Meets EU Directive 2011/65/EU with lead-free matte-tin plating and halogen-free epoxy body |
| High surge current capability | Withstands 150 A non-repetitive surges - suitable for transient voltage suppression in industrial power inputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5364BRLG | Same 33 V/±5%/5 W specs; leaded, RoHS-compliant, but supplied in bulk (not tape-and-reel) | No TR12 packaging - unsuitable for automated pick-and-place; requires manual or vibratory feeding | Select 1N5364BRLG only for prototyping or low-volume hand-soldered assemblies |
| MMSZ5256ET1G | Surface-mount SOD-123 package; 33 V/±5%, but rated for 500 mW only and 100 mA IZM | Limited power handling - cannot replace 1N5364BE3/TR12 in 5 W applications without derating or parallel devices | Choose MMSZ5256ET1G only for space-constrained PCBs where thermal management allows <0.5 W operation |
Compared with 1N5364BRLG and MMSZ5256ET1G, the 1N5364BE3/TR12 uniquely combines axial-leaded manufacturability, full 5 W power rating, tape-and-reel delivery for SMT lines, and industrial-grade temperature range - making it optimal for high-reliability power supply and protection designs requiring proven thermal robustness.

FAQ
What is the Zener voltage tolerance for 1N5364BE3/TR12?
The 1N5364BE3/TR12 has a ±5% Zener voltage tolerance, confirmed by the "B" suffix in its part number per Microsemi's datasheet. This means its actual breakdown voltage falls between 31.35 V and 34.65 V at 40 mA test current and 25 °C lead temperature. The e3 suffix indicates RoHS compliance, and TR12 denotes tape-and-reel packaging with 12,000 units per reel - all attributes fully specified in the official 1N5333B–1N5388B datasheet revision D.
Can 1N5364BE3/TR12 be used in surface-mount designs?
No, the 1N5364BE3/TR12 is an axial-leaded T-18 package and is not compatible with surface-mount assembly processes. For SMT equivalents, Microsemi offers the SMBJ5364B or SMBG5364B in DO-214AA/DO-214AB packages. These share identical 33 V/±5%/5 W electrical specifications but require different footprint, reflow profile, and thermal pad layout - direct substitution would necessitate PCB redesign and validation.
What is the maximum power dissipation of 1N5364BE3/TR12 at 70°C ambient?
At 70 °C ambient temperature, the 1N5364BE3/TR12 must be derated based on its thermal resistance. When mounted on FR4 with 1 oz copper (85 °C/W junction-to-ambient), its steady-state power drops to approximately 0.86 W - calculated as (150 °C − 70 °C) / 85 °C/W. This assumes no additional heatsinking; using the 25 °C/W junction-to-lead spec requires maintaining lead temperature ≤25 °C via heatsink or chassis connection to sustain full 5 W operation.
Does 1N5364BE3/TR12 meet MIL-PRF-19500 screening requirements?
No, the 1N5364BE3/TR12 is not screened to MIL-PRF-19500 standards. Per Microsemi's documentation, military-grade versions require prefix additions: MQ (JAN), MX (JANTX), or MV (JANTXV). The base part number lacks these prefixes and is commercial-grade, qualified per standard JEDEC test methods only - suitable for industrial applications but not for aerospace or defense programs requiring MIL-spec screening.
What is the reverse leakage current specification for 1N5364BE3/TR12?
The reverse leakage current (IR) for 1N5364BE3/TR12 is specified as 0.5 μA maximum at 25.1 V reverse voltage (VR), per the "B" suffix column in the Electrical Characteristics table. This value is measured at 25 °C and reflects the diode's ability to block current below its Zener knee - critical for minimizing standby power loss in high-impedance reference networks and ensuring accurate voltage threshold detection.
