Product details
Overview
1N5364CE3/TR13 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 33 V, ±2% tolerance (C suffix), 10 Ω maximum dynamic impedance at 40 mA test current, and 150 mA maximum Zener current 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 1N5364CE3/TR13 datasheet, 1N5364CE3/TR13 pinout, 1N5364CE3/TR13 application, or 1N5364CE3/TR13 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 25.1 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 mode, with Zener voltage defined at 40 mA test current and specified under controlled lead temperature (TL = 25 °C). Its low dynamic impedance (10 Ω) ensures minimal voltage variation across load current changes within its rated power envelope.
The 1N5364CE3/TR13 uses a void-free thermosetting epoxy T-18 package with cathode band marking, rated for 5 W steady-state dissipation at TL < 25 °C (3/8″ lead length), and exhibits 0.6 V maximum voltage regulation (ΔVZ) between 10% and 50% of IZM - confirming tight regulation stability over operating current range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 33 V ±2% - precise reference point for feedback loops in regulated DC-DC converters |
| Test Current (IZT) | 40 mA - standardized bias point for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZ) | 10 Ω max - low AC resistance ensures stable output under varying load transients |
| Max Reverse Leakage (IR) | 0.5 µA at 25.1 V - negligible standby current in high-impedance sensing circuits |
| Max Zener Current (IZM) | 150 mA - defines absolute DC current limit before thermal runaway without heatsinking |
| Surge Current (IZSM) | 150 A (8.3 ms half-sine) - supports transient overvoltage clamping in surge protection stages |
| Voltage Regulation (ΔVZ) | 0.6 V max - difference between VZ measured at 15 mA and 75 mA confirms line regulation fidelity |
Pinout & Package
Package: T-18 axial-leaded plastic encapsulated case (void-free UL94V-0 epoxy), cathode indicated by colored band; leads are annealed matte-tin plated per MIL-STD-750 Method 2026, RoHS compliant (e3 suffix), weight 0.7 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-bias operation | Connected to lower-potential rail; forms return path during Zener conduction |
| Cathode | Regulated output node | Banded end; held at stable 33 V relative to anode when reverse current ≥40 mA |
Key Features
| Feature | Design Value |
|---|---|
| ±2% Zener voltage tolerance | Enables use in precision references without post-calibration trimming |
| 25 °C/W junction-to-lead thermal resistance | Allows 5 W dissipation with modest heatsinking (e.g., 3/8″ lead length) |
| Moisture sensitivity Level 1 (J-STD-020B) | Eliminates dry-pack requirement and floor-life constraints for SMT reflow prep |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Permits handling without special static-control protocols in assembly environments |
| RoHS-compliant matte-tin plating | Ensures solderability compatibility with Pb-free reflow profiles up to 260 °C/10 s |
Applications
| Industrial Power Supply Feedback | Overvoltage Clamp in Telecom Line Cards |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback converters via optocoupler-coupled feedback loop. IC Role / Device Role / Timing Role: Precision voltage reference providing error signal to PWM controller.

Use Scenario: Setting trip point for undervoltage lockout (UVLO) or overvoltage detection comparators. IC Role / Device Role / Timing Role: Stable DC reference input to comparator hysteresis network. Use Value: Low 0.5 µA leakage at 25.1 V prevents false triggering in high-impedance sense nodes. | Use Scenario: Providing excitation voltage to resistive sensor bridges feeding 12-bit SAR ADCs. IC Role / Device Role / Timing Role: Low-noise, low-drift analog reference source. Use Value: 10 Ω ZZ minimizes current-dependent offset error across sensor excitation current range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5364B | Same 33 V nominal VZ, but ±5% tolerance (B suffix) and higher ZZ (10 Ω vs. 10 Ω - identical spec, but B-grade may exhibit wider batch variation) | Suitable where tighter tolerance not required; lower cost in non-critical references | Select 1N5364B only if system-level calibration accommodates ±5% VZ drift. |
| MMSZ5255ET1G | Surface-mount SOD-123 package, 33 V ±5%, 500 mW rating, 30 Ω ZZ - not drop-in; requires layout change and derating for same power | Used in space-constrained PCBs where axial leads are impractical | Choose MMSZ5255ET1G only when board area is critical and thermal management allows 500 mW operation. |
Compared with 1N5364B and MMSZ5255ET1G, the 1N5364CE3/TR13 delivers superior voltage accuracy (±2% vs. ±5%), higher power handling (5 W vs. 0.5 W), and lower dynamic impedance - making it optimal for industrial-grade regulation where stability and surge resilience are mandatory.

FAQ
What is the Zener voltage tolerance of the 1N5364CE3/TR13?
The 1N5364CE3/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 32.34 V and 33.66 V at 40 mA test current and 25 °C lead temperature - enabling use in applications demanding tighter reference accuracy than standard ±5% devices like the 1N5364B.
Does the 1N5364CE3/TR13 require dry packing before reflow soldering?
No, the 1N5364CE3/TR13 does not require dry packing. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1, meaning it can be stored indefinitely at ambient conditions without baking prior to soldering - simplifying manufacturing logistics and eliminating floor-life tracking for this device.
What is the maximum surge current rating for the 1N5364CE3/TR13?
The 1N5364CE3/TR13 is rated for a maximum non-recurrent surge current (IZSM) of 150 A, defined as the peak value of an 8.3 ms half-sine waveform. This rating supports transient suppression in power-line protection circuits where short-duration overvoltages must be safely clamped without device failure.
How does the thermal resistance of the 1N5364CE3/TR13 affect its power dissipation capability?
The 1N5364CE3/TR13 has a junction-to-lead thermal resistance of 25 °C/W at 3/8″ (10 mm) lead length. At 25 °C ambient, this allows full 5 W dissipation; above that temperature, power must be linearly derated - e.g., at 75 °C lead temperature, maximum safe dissipation drops to 4 W - ensuring junction temperature remains below 150 °C.
Is the 1N5364CE3/TR13 compatible with lead-free reflow processes?
Yes, the 1N5364CE3/TR13 is RoHS compliant (e3 suffix) and features annealed matte-tin plating qualified per MIL-STD-750 Method 2026. It withstands peak solder temperatures of 260 °C for up to 10 seconds - fully compatible with standard Pb-free reflow profiles used in modern electronics assembly.
