Product details
Overview
1N5364C/TR12 from Microsemi is a 5 W axial-leaded silicon Zener diode with a nominal regulation voltage of 33 V, ±2% tolerance (C suffix), 40 mA test current, and 10 Ω maximum dynamic impedance at IZT. 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 1N5364C/TR12 datasheet, 1N5364C/TR12 pinout, 1N5364C/TR12 application, or 1N5364C/TR12 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), surge current rating (150 A), and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device functions as a two-terminal voltage regulator in reverse-biased mode, with cathode indicated by a band. Its low dynamic impedance (10 Ω) ensures stable regulation across 10–50% of IZM, and its 25 °C/W junction-to-lead thermal resistance enables reliable 5 W operation when leads are mounted ≥10 mm from body.
The 1N5364C/TR12 meets JEDEC 1N53xxB series specifications, uses void-free UL94V-0 epoxy encapsulation, and is rated for 260 °C soldering (10 s). It exhibits ≤0.5 μA reverse leakage at 25.1 V and supports tape-and-reel packaging (TR12 suffix).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 33 V ±2% - precise regulation point for feedback loops requiring tight voltage stability |
| Test Current (IZT) | 40 mA - operating point where VZ and ZZ are specified; defines minimum bias for regulation |
| Dynamic Impedance (ZZ) | 10 Ω max at IZT - low AC resistance ensures minimal output voltage variation under load transients |
| Max Regulator Current (IZM) | 150 mA - maximum DC current at 25 °C lead temperature; determines power handling with heat sinking |
| Surge Current (IZSM) | 150 A (8.3 ms half-sine) - withstands short-duration overvoltage events without failure |
| Thermal Resistance (RθJL) | 25 °C/W junction-to-lead - enables 5 W dissipation with modest heatsinking at 3/8″ lead length |
| Reverse Leakage (IR) | ≤0.5 μA at 25.1 V - negligible standby current in high-impedance sensing or reference circuits |
Pinout & Package
Package: Axial-leaded T-18 plastic case (void-free UL94V-0 epoxy), cathode identified by color band; RoHS-compliant matte-tin plating on annealed copper leads; weight 0.7 g; moisture sensitivity level 1 (no dry pack required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to circuit common; reverse-bias polarity requires cathode at higher potential |
| Cathode | Regulated output node | Banded end; held at stable 33 V relative to anode during conduction; must be biased above anode by ≥33 V |
Key Features
| Feature | Design Value |
|---|---|
| ±2% Zener voltage tolerance | Enables accurate voltage references without post-calibration in analog control and sensing circuits |
| JEDEC 1N53xxB registration | Guarantees mechanical and electrical interchangeability with industry-standard 5 W Zener footprints |
| RoHS-compliant e3 marking | Meets global environmental compliance requirements for industrial and telecom equipment manufacturing |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Eliminates need for special ESD handling during assembly and field service |
| Level 1 moisture sensitivity | Allows standard SMT/reflow processes without baking or dry-pack storage |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5364B/TR13 | ±5% tolerance (B suffix), same VZ = 33 V, identical package and IZM | Lower cost where ±5% regulation accuracy is acceptable | Select for non-critical biasing or coarse voltage clamping where tighter tolerance is unnecessary |
| MMSZ5255ET1G | Surface-mount SOD-123, 500 mW, VZ = 33 V ±5%, ZZ = 35 Ω | Not suitable for 5 W continuous dissipation; limited to low-power PCB space-constrained designs | Choose only for compact consumer electronics where power and surge capability are secondary to footprint |
Compared with 1N5364B/TR13 and MMSZ5255ET1G, the 1N5364C/TR12 delivers superior voltage accuracy and 10× higher power handling-critical for industrial power rails-but requires axial through-hole mounting and larger board area.

FAQ
What is the Zener voltage tolerance of the 1N5364C/TR12?
The 1N5364C/TR12 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix. This means its regulated voltage falls within 32.34 V to 33.66 V at 40 mA test current and 25 °C lead temperature. This tighter tolerance supports precision applications such as feedback references where calibration margin is constrained.
Can the 1N5364C/TR12 be used in surface-mount designs?
No-the 1N5364C/TR12 is an axial-leaded T-18 package and is not compatible with surface-mount assembly. For SMT equivalents, Microsemi offers the SMBJ5364B series; however, those parts differ in power rating (5 W vs. lower), package, and thermal performance. The 1N5364C/TR12 requires through-hole mounting with ≥10 mm lead length for rated 5 W operation.
What is the maximum steady-state power dissipation of the 1N5364C/TR12 on a standard PCB?
When mounted on a FR4 PCB (1 oz Cu) with 4 mm² copper pads and 1 mm × 25 mm traces, the 1N5364C/TR12 has a steady-state power rating of 1.47 W at 25 °C ambient. This derates linearly above 25 °C per the published thermal resistance of 85 °C/W junction-to-ambient. Full 5 W operation requires lead temperature control at ≤25 °C via heatsinking.
Does the 1N5364C/TR12 meet RoHS requirements?
Yes-the "e3" designation in Microsemi's documentation confirms the 1N5364C/TR12 is RoHS compliant, using matte-tin plating per J-STD-609. The "TR12" suffix indicates tape-and-reel packaging per EIA-296, and the device contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits.
How does the 1N5364C/TR12 handle surge conditions?
The 1N5364C/TR12 is rated for a peak non-recurrent surge current (IZSM) of 150 A, defined as an 8.3 ms half-sine waveform. This allows it to absorb transient overvoltages-such as those from inductive switching or lightning-induced surges-without parametric shift or catastrophic failure, provided average power remains within derated limits.
