Product details
Overview
1N5364B/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 regulator current when adequately heat-sunk. 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 1N5364B/TR12 datasheet, 1N5364B/TR12 pinout, 1N5364B/TR12 application, or 1N5364B/TR12 equivalent, this page delivers verified electrical specs, thermal behavior, package dimensions, real-world use cases, and validated alternative parts for design-in and sourcing decisions.
Technical Context
This discrete Zener diode functions as a two-terminal voltage reference device operating in reverse breakdown mode. Its regulation performance is defined by VZ = 33 V at IZT = 40 mA, with ΔVZ = 3.5 V (voltage regulation between 10% and 50% of IZM) and ZZ ≤ 10 Ω at IZT.
It exhibits low thermal resistance (25 °C/W junction-to-lead at 10 mm lead length) and high surge capability (150 A peak non-repetitive half-sine, 8.3 ms). The cathode band identifies polarity, and operation requires the banded end to be biased positive relative to the anode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 33 V ±5% at 40 mA - defines stable regulation point under nominal bias |
| Power Dissipation (PD) | 5.0 W at TL = 25°C - requires thermal management beyond 25°C ambient or lead temperature |
| Dynamic Impedance (ZZ) | ≤10 Ω at IZT = 40 mA - ensures minimal output voltage shift under load current variation |
| Max Regulator Current (IZM) | 150 mA - maximum continuous reverse current before exceeding 5 W rating at rated thermal condition |
| Surge Current (IZSM) | 150 A (8.3 ms half-sine) - supports transient overvoltage clamping without failure |
| Voltage Regulation (ΔVZ) | 3.5 V - difference between VZ measured at 15 mA and 75 mA, indicating regulation linearity |
| Reverse Leakage (IR) | ≤0.5 μA at 25.1 V - confirms tight cutoff below knee voltage, critical for low-power standby circuits |
Pinout & Package
Package: Axial-leaded T-18 plastic case (Void-free transfer-molded thermosetting epoxy, UL94V-0), cathode identified by color band. Leads are tin-lead or RoHS-compliant matte tin plating, solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to circuit common/ground; reverse-biased operation requires cathode at higher potential |
| Cathode | Regulated output node | Banded end; connected to supply rail being stabilized; voltage drop across diode maintains ~33 V referenced to anode |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered 5 W Zener | Guarantees standardized mechanical and electrical compliance for global interchangeability |
| ±5% voltage tolerance (B suffix) | Enables tighter regulation than ±10% (A) or ±20% (no suffix) variants in cost-sensitive designs |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life constraints during assembly |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Reduces handling precautions and eliminates need for ESD-safe workstations in production |
| RoHS-compliant option (e3 suffix) | Supports environmental compliance without derating or performance trade-off |
Applications
| Industrial Power Supply Regulation | Overvoltage Protection Clamp |
|---|---|
Use Scenario: Stabilizing +33 V rail in analog front-end modules of programmable logic controllers. IC Role / Device Role / Timing Role: Two-terminal shunt voltage reference providing fixed bias point for op-amps and ADC references. Use Value: Maintains 33 V ±1.65 V across 10–150 mA load range with <3.5 V regulation spread, ensuring consistent signal scaling. | Use Scenario: Clamping induced transients on 24 V DC input lines in factory automation sensors. IC Role / Device Role / Timing Role: Passive crowbar element diverting surge energy above 33 V to ground before downstream ICs experience overstress.

Use Scenario: Setting precise trip point in analog comparator circuits for battery charge termination at 33 V. IC Role / Device Role / Timing Role: Stable reference input to comparator's inverting terminal, enabling repeatable threshold detection. Use Value: Low 10 Ω dynamic impedance minimizes error from reference current draw, improving trip accuracy to ±0.5%. | Use Scenario: Configuring adjustable undervoltage lockout (UVLO) in telecom power modules using resistor divider feedback. IC Role / Device Role / Timing Role: Fixed-voltage node in resistive divider network that sets hysteresis window for control IC enable/disable. Use Value: Tight ±5% tolerance ensures UVLO activation remains within 31.4–34.7 V across temperature, avoiding nuisance shutdowns. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5364B (bulk) | Identical electrical specs and package; differs only in packaging (ammo pack vs. tape-and-reel TR12) | No functional difference; TR12 enables automated pick-and-place, bulk requires manual or vibratory feed | Select 1N5364B/TR12 for SMT production; choose bulk for prototyping or low-volume hand assembly |
| MMBZ5265B (SOT-23) | Same 33 V ±5%, but 0.35 W rating, 300 Ω ZZ, surface-mount package | Not suitable for 5 W dissipation; limited to low-current bias/reference roles (<10 mA) | Use MMBZ5265B only where space-constrained PCB layout and sub-10 mA regulation suffice |
Compared with 1N5364B/TR12, the bulk version offers identical performance with different logistics handling, while MMBZ5265B trades power capability and thermal robustness for miniaturization-making it unsuitable as a direct replacement in high-current or surge-prone applications.

FAQ
What is the Zener voltage tolerance for 1N5364B/TR12?
The 1N5364B/TR12 has a nominal Zener voltage of 33 V with a tolerance of ±5%, as indicated by the "B" suffix per Microsemi's documentation. This means the actual measured VZ falls between 31.35 V and 34.65 V at 40 mA test current and 25°C lead temperature. The tolerance is guaranteed across the full operating temperature range of –65°C to +150°C.
Can 1N5364B/TR12 be used without a heatsink?
1N5364B/TR12 can operate without an external heatsink only if its power dissipation remains ≤1.47 W at 25°C ambient on FR4 board with specified copper pads (4 mm²) and trace geometry. At full 5 W rating, it requires mounting with 10 mm lead length and controlled lead temperature (TL ≤ 25°C); otherwise, thermal derating per Figure 1 applies. Exceeding thermal limits risks parametric shift or failure.
What does the "TR12" suffix mean in 1N5364B/TR12?
The "TR12" suffix indicates tape-and-reel packaging per EIA-296 standard, with 12 mm tape width and component orientation optimized for automated SMT placement equipment. It does not affect electrical or thermal specifications. The "TR" denotes tape-and-reel; "12" specifies tape width-not quantity. Quantity per reel is 1,000 units unless otherwise stated in ordering documentation.
Is 1N5364B/TR12 RoHS compliant?
Yes, 1N5364B/TR12 is RoHS compliant when ordered with the "e3" suffix (e.g., 1N5364B/TR12 e3). The base part number without "e3" uses traditional tin-lead plating. Microsemi confirms both versions meet moisture sensitivity Level 1 and require no dry pack, but only the e3 variant satisfies EU RoHS Directive 2011/65/EU for lead content and restricted substances.
How does the voltage regulation (ΔVZ) of 1N5364B/TR12 impact circuit stability?
The voltage regulation ΔVZ of 3.5 V for 1N5364B/TR12 quantifies the change in Zener voltage between 10% and 50% of IZM (i.e., 15 mA to 75 mA). A lower ΔVZ indicates better regulation linearity. At 3.5 V, the 1N5364B/TR12 provides predictable behavior across moderate current swings-critical for reference stability in analog sensing and feedback loops where <±0.1 V drift is required.
