Product details
Overview
1N5371BE3/TR13 from Microsemi is a 5.0 W axial-leaded silicon Zener diode with nominal regulation voltage of 60 V, ±5% tolerance (B suffix), maximum dynamic impedance of 40 Ω at 20 mA test current, and maximum reverse current of 0.5 μA at 45.5 V. 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 1N5371BE3/TR13 datasheet, 1N5371BE3/TR13 pinout, 1N5371BE3/TR13 application, or 1N5371BE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (25 °C/W junction-to-lead), surge current rating (350 A), voltage regulation (ΔVZ = 2.2 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, where the cathode band indicates the positive terminal during regulation. Its low dynamic impedance (40 Ω) and tight voltage regulation (2.2 V between 10% and 50% of IZM) ensure stable reference performance across varying load currents.
The 1N5371BE3/TR13 uses void-free thermosetting epoxy encapsulation (UL94V-0), achieves moisture sensitivity level 1 (no dry pack required), and supports axial-lead mounting with 3/8" (10 mm) lead length defining its 25 °C/W thermal resistance path from junction to lead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 60 V ±5% - defines precise regulation point for feedback loops and reference circuits |
| Test Current (IZT) | 20 mA - standard bias condition for measuring VZ and ZZ |
| Dynamic Impedance (ZZ) | 40 Ω max at 20 mA - determines output voltage stability under load variation |
| Max Reverse Current (IR) | 0.5 μA at 45.5 V - ensures minimal leakage in high-impedance sensing paths |
| Power Dissipation (PD) | 5.0 W at TL = 25°C - sets maximum steady-state thermal design limit with adequate heatsinking |
| Surge Current (IZSM) | 350 A (8.3 ms half-sine) - enables transient overvoltage clamping without failure |
| Voltage Regulation (ΔVZ) | 2.2 V - difference between VZ measured at 10% and 50% of IZM, indicating line regulation capability |
Pinout & Package
Package: Axial-leaded T-18 plastic case (void-free thermosetting epoxy, UL94V-0), cathode indicated by color band. Leads are annealed matte-tin plated (RoHS compliant, solderable per MIL-STD-750 Method 2026).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lower-potential rail; reverse-biased operation requires cathode at higher potential |
| Cathode | Regulated output node | Banded end; supplies stable 60 V reference when reverse-biased above breakdown threshold |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered Zener family | Ensures standardized mechanical dimensions, electrical behavior, and interchangeability across qualified suppliers |
| ±5% voltage tolerance (B suffix) | Supports mid-precision regulation without requiring post-calibration in cost-sensitive industrial designs |
| 25 °C/W junction-to-lead thermal resistance | Enables reliable 5 W operation with simple lead-length heatsinking (3/8" from body), reducing need for PCB copper pour |
| RoHS-compliant e3 suffix | Meets global environmental compliance requirements without performance trade-offs or process requalification |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Eliminates need for handling precautions during assembly, lowering manufacturing risk and cost |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5371B (non-e3, non-TR) | Same electrical specs but SnPb plating and bulk packaging; lacks RoHS compliance and tape-and-reel convenience | Not suitable for RoHS-mandated production or automated pick-and-place assembly | Select 1N5371BE3/TR13 when environmental compliance and SMT-line compatibility are required |
| MMSZ5257ET1G (ON Semiconductor) | Surface-mount SOD-123 package, 500 mW rating, 60 V ±5%, 100 Ω ZZ, 1 μA IR at 45.5 V | Lower power and higher impedance limit use to low-current references; unsuitable for 5 W clamping | Choose MMSZ5257ET1G only for space-constrained, low-power biasing where board area is critical |
Compared with 1N5371B and MMSZ5257ET1G, the 1N5371BE3/TR13 uniquely combines 5 W power handling, axial-leaded robustness, RoHS compliance, and tape-and-reel delivery-making it optimal for industrial power and protection designs requiring reliability, thermal margin, and manufacturing readiness.

FAQ
What is the Zener voltage tolerance for 1N5371BE3/TR13?
The 1N5371BE3/TR13 has a Zener voltage tolerance of ±5%, indicated by the "B" suffix in its part number. This means its nominal 60 V regulation voltage falls within 57 V to 63 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 standards. This tolerance supports mid-precision applications without requiring calibration.
What is the maximum surge current rating for 1N5371BE3/TR13?
The 1N5371BE3/TR13 is rated for a maximum non-recurrent surge current (IZSM) of 350 A, defined as the peak of an 8.3 ms half-sine waveform. This rating applies under specified mounting conditions and enables the device to absorb transient overvoltages-such as those from inductive switching or lightning-induced surges-without permanent degradation. Its 5 W steady-state power rating complements this surge capability for sustained clamping duty.
How does the thermal resistance of 1N5371BE3/TR13 affect its power handling?
The 1N5371BE3/TR13 has a junction-to-lead thermal resistance of 25 °C/W when mounted with 3/8" (10 mm) lead length from the body. This allows full 5.0 W dissipation at 25°C lead temperature. At higher ambient temperatures or with shorter leads, derating is required per Figure 1 in the datasheet. Unlike FR4-board-mounted thermal resistance (85 °C/W), the lead-based path provides superior heat transfer for chassis- or heatsink-mounted implementations.
Is 1N5371BE3/TR13 suitable for surface-mount assembly?
No, the 1N5371BE3/TR13 is an axial-leaded T-18 package and is not compatible with surface-mount reflow processes. It is designed for through-hole mounting with manual or wave soldering. For surface-mount equivalents, Microsemi offers the SMBJ5371B and SMBG5371B in DO-214AA/DO-214AB packages-though these differ in power rating, thermal performance, and footprint. The TR13 tape-and-reel format supports automated insertion, not SMT placement.
What does the "e3" and "TR13" suffix mean in 1N5371BE3/TR13?
The "e3" suffix indicates RoHS-compliant matte-tin plating on the leads, meeting EU Directive 2011/65/EU and related environmental standards. The "TR13" denotes tape-and-reel packaging per EIA-296 specification, with 13-inch reels optimized for automated component placement equipment. Together, these suffixes confirm that the 1N5371BE3/TR13 is both environmentally compliant and production-ready for high-volume manufacturing environments.
