Product details
Overview
1N5364BE3/TR13 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 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 1N5364BE3/TR13 datasheet, 1N5364BE3/TR13 pinout, 1N5364BE3/TR13 application, or 1N5364BE3/TR13 equivalent, key selection criteria include Zener voltage stability under varying load current, low voltage regulation (ΔVZ = 3.5 V), thermal resistance (25 °C/W junction-to-lead), RoHS compliance (e3 suffix), and tape-and-reel packaging (TR13).
Technical Context
This discrete Zener diode functions as a two-terminal shunt voltage regulator, maintaining stable output voltage by conducting reverse current above its breakdown threshold. Its design supports high surge current handling (150 A peak, 8.3 ms half-sine) and exhibits minimal voltage drift versus temperature due to low thermal resistance and tight ±5% tolerance.
The device uses void-free thermosetting epoxy encapsulation (UL94V-0), tin-plated leads compliant with MIL-STD-750 Method 2026, and features cathode band polarity marking. It is moisture-sensitive Level 1 per J-STD-020B - no dry pack required - and rated for 1.2 V forward voltage max at 1.0 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 33 V nominal, ±5% tolerance - ensures stable regulation within 31.35–34.65 V range at 40 mA test current. |
| Power Dissipation | 5.0 W at 25 °C lead temperature - requires thermal management beyond 25 °C per derating curve (25 °C/W junction-to-lead). |
| Dynamic Impedance (ZZ) | 10 Ω max at IZT = 40 mA - low impedance minimizes output voltage variation under changing load current. |
| Reverse Current (IR) | 0.5 μA max at VR = 25.1 V - confirms sharp knee and low leakage below breakdown. |
| Voltage Regulation (ΔVZ) | 3.5 V max - difference between VZ measured at 10% and 50% of IZM, indicating regulation linearity. |
| Surge Current (IZSM) | 150 A peak (8.3 ms half-sine) - enables robust transient suppression without failure. |
| Operating Temperature | –65 °C to +150 °C - suitable for harsh environments including automotive under-hood and industrial control cabinets. |
Pinout & Package
Package: Axial-leaded T-18 plastic case (void-free UL94V-0 epoxy), 0.7 g weight, cathode indicated by colored band. Leads are annealed matte-tin plated, solderable per MIL-STD-750 Method 2026. Soldering: 260 °C for 10 s max.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Non-banded lead | Connected to lower-potential node; reverse-biased operation requires this terminal to be negative relative to cathode. |
| Cathode | Banded lead | Connected to regulated voltage rail; conducts reverse current to clamp voltage at VZ during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered Zener family | Industry-standard 1N53xxB series ensures cross-manufacturer compatibility and long-term supply stability. |
| RoHS-compliant construction | e3 suffix certifies lead-free plating and halogen-free epoxy - meets EU RoHS Directive 2011/65/EU. |
| Tight voltage tolerance | ±5% (B suffix) enables predictable regulation without post-production trimming in fixed-voltage reference designs. |
| High surge withstand capability | 150 A non-recurrent surge rating allows use in input-stage transient protection without external crowbar circuits. |
| Level 1 moisture sensitivity | No dry-pack or baking required before PCB assembly - reduces manufacturing overhead and avoids moisture-induced popcorning. |

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 (no e3/TR) | Same electrical specs, but leaded (non-RoHS) plating and bulk packaging - not compliant with modern environmental directives. | Restricted to legacy repair or non-export programs where RoHS exemption applies. | Select 1N5364BE3/TR13 for new designs requiring RoHS compliance and automated placement. |
| MMSZ5255B-TP (Micro Commercial Components) | Surface-mount SOD-123 package, 33 V ±5%, 500 mW rating - lower power, higher ZZ (35 Ω), no surge rating specified. | Suitable only for low-power biasing or signal-level clamping; cannot replace 1N5364BE3/TR13 in 5 W power regulation roles. | Choose MMSZ5255B-TP only for space-constrained PCBs where thermal mass and surge immunity are secondary. |
Compared with 1N5364B and MMSZ5255B-TP, the 1N5364BE3/TR13 uniquely combines 5 W power handling, 150 A surge capability, RoHS compliance, and tape-and-reel delivery - making it the sole option for high-reliability, through-hole, industrial-grade 33 V regulation.

FAQ
What is the Zener voltage tolerance of the 1N5364BE3/TR13?
The 1N5364BE3/TR13 has a ±5% Zener voltage tolerance, confirmed by the "B" suffix in its part number per Microsemi's datasheet revision D. This means its actual regulation voltage falls between 31.35 V and 34.65 V when measured at 40 mA test current and 25 °C lead temperature. The e3 suffix indicates RoHS compliance but does not affect voltage tolerance.
Can the 1N5364BE3/TR13 be used without a heatsink?
The 1N5364BE3/TR13 can operate without an external heatsink only at significantly derated power - its full 5 W rating applies only at 25 °C lead temperature (TL). On a standard FR4 PCB with 1 oz copper, its steady-state power drops to 1.47 W at 25 °C ambient. For continuous 5 W operation, a minimum 3/8-inch (10 mm) lead length from body and adequate copper pour are required to maintain TL ≤ 25 °C.
What does the "TR13" suffix indicate in 1N5364BE3/TR13?
The "TR13" suffix denotes tape-and-reel packaging per EIA-296 standard, with 13-inch reels. This format enables automated surface-mount or through-hole placement in high-volume manufacturing. The base part 1N5364BE3 remains electrically and mechanically identical - TR13 adds only packaging configuration and reel quantity (typically 1,000 units per reel).
Is the 1N5364BE3/TR13 suitable for surge protection applications?
Yes - the 1N5364BE3/TR13 is explicitly rated for 150 A non-recurrent surge current (8.3 ms half-sine wave), making it suitable for transient voltage suppression in DC power rails. Its low dynamic impedance (10 Ω) and high IZM (150 mA) allow rapid clamping with minimal overshoot, though it is not a replacement for dedicated TVS diodes in fast-rising ESD events (>1 kV/ns).
How does the 1N5364BE3/TR13 compare to the 1N4749A?
The 1N5364BE3/TR13 (33 V, 5 W, ±5%) differs from the 1N4749A (33 V, 1 W, ±5%) primarily in power rating and thermal performance. The 1N5364BE3/TR13 supports 5× higher power dissipation and 150 A surge current, while the 1N4749A is limited to 1 W and lacks published surge ratings. They share identical Zener voltage but are not interchangeable without thermal redesign.
