Product details
Overview
1N5372BE3/TR13 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 62 V, ±5% tolerance (B suffix), 20 mA test current, 42 Ω dynamic impedance at IZT, and maximum reverse current of 0.5 μA at 47.1 V. It regulates voltage in power supply feedback loops and overvoltage protection circuits across industrial power converters.
For engineers reviewing the 1N5372BE3/TR13 datasheet, 1N5372BE3/TR13 pinout, 1N5372BE3/TR13 application, or 1N5372BE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (25 °C/W junction-to-lead), surge current rating (400 A), voltage regulation (ΔVZ = 2.1 V), and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device operates as a precision shunt regulator in reverse-biased mode, maintaining stable output voltage under varying load and line conditions. Its low dynamic impedance (42 Ω) and tight voltage regulation (2.1 V between 10% and 50% of IZM) ensure minimal output drift across operating current range.
The 1N5372BE3/TR13 uses void-free thermosetting epoxy encapsulation (UL94V-0), cathode band polarity marking, and is rated for -65 °C to +150 °C operation. Thermal resistance is specified at 25 °C/W junction-to-lead (3/8" lead length) and 85 °C/W junction-to-ambient on FR4 board - critical for heatsink design in high-current applications.
Key Specifications

Use Value: Enables fast response (<100 ns) to overvoltage events due to low capacitance and sharp knee characteristic. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5372B | Same Zener voltage (62 V), ±5% tolerance, but no e3 RoHS suffix or TR13 tape-and-reel packaging | Non-RoHS version; requires leaded solder process or exemption documentation | Select when legacy compliance or cost-sensitive non-RoHS production is required |
| SMBJ5372B | Surface-mount SMB package (JEDEC DO-214AA), same 62 V/±5%/5 W rating, but higher thermal resistance (junction-to-ambient ~100 °C/W) | Replaces axial leads in space-constrained PCB layouts; requires reflow profile validation | Select for automated SMT assembly where board real estate is limited and thermal derating is acceptable |
Compared with 1N5372B and SMBJ5372B, the 1N5372BE3/TR13 uniquely combines RoHS compliance, tape-and-reel delivery for pick-and-place, and low junction-to-lead thermal resistance (25 °C/W) - making it optimal for through-hole industrial power supplies requiring long-term regulatory compliance and thermal reliability.

FAQ
What is the Zener voltage tolerance for 1N5372BE3/TR13?
The 1N5372BE3/TR13 has a Zener voltage tolerance of ±5%, indicated by the "B" suffix in its part number. This means its nominal 62 V regulation voltage falls within 58.9 V to 65.1 V at 20 mA test current and 25 °C lead temperature. The e3 suffix confirms RoHS compliance, and TR13 denotes tape-and-reel packaging per EIA-296 standard.
What is the maximum steady-state power dissipation for 1N5372BE3/TR13?
The 1N5372BE3/TR13 delivers 5.0 W steady-state power dissipation when lead temperature (TL) is maintained below 25 °C, measured at 3/8 inch (10 mm) from the body. On FR4 PCB with 1 oz copper, 4 mm² pads, and 1 mm × 25 mm traces, its derated power drops to 1.47 W at 25 °C ambient - a critical constraint for thermal design in enclosed enclosures.
How does the voltage regulation (ΔVZ) specification impact circuit performance for 1N5372BE3/TR13?
The 1N5372BE3/TR13 specifies ΔVZ = 2.1 V - the difference between Zener voltage measured at 10% and 50% of its maximum current (IZM). This quantifies regulation linearity: a lower ΔVZ indicates tighter voltage stability across load changes. For 1N5372BE3/TR13, this enables ±0.5% output variation in feedback loops where IZ varies between 1.2 A and 6 A.
What is the surge current rating for 1N5372BE3/TR13 and how is it defined?
The 1N5372BE3/TR13 supports a non-repetitive peak surge current (IZSM) of 400 A, defined as the maximum amplitude of an 8.3 ms half-sine waveform. This rating reflects its ability to absorb transient energy without parametric shift or catastrophic failure - essential for protecting downstream circuitry from lightning strikes or inductive kickback in industrial motor controls.
Is 1N5372BE3/TR13 suitable for surface-mount assembly?
No, the 1N5372BE3/TR13 is an axial-leaded T-18 (DO-201AD) package intended for through-hole mounting. For surface-mount equivalents, Microsemi offers the SMBJ5372B in DO-214AA package. While both share identical electrical specs (62 V, ±5%, 5 W), the SMBJ5372B has higher thermal resistance and requires reflow soldering - making 1N5372BE3/TR13 unsuitable for SMT lines without adapter hardware.
