Product details
Overview
1N5367AE3/TR13 from Microsemi is a 43 V, ±10% tolerance, 5 W axial-leaded silicon Zener diode optimized for voltage regulation in power supply reference and overvoltage protection circuits. It delivers 30 mA maximum Zener current (IZM) at 25°C with 20 Ω dynamic impedance (ZZ) and operates across –65°C to +150°C.
For engineers reviewing the 1N5367AE3/TR13 datasheet, 1N5367AE3/TR13 pinout, 1N5367AE3/TR13 application, or 1N5367AE3/TR13 equivalent, key selection criteria include its 43 V nominal Zener voltage, ±10% tolerance (A suffix), RoHS-compliant matte-tin plating, tape-and-reel packaging (TR13), and thermal resistance of 25 °C/W junction-to-lead.
Technical Context
This device functions as a precision shunt regulator, maintaining stable output voltage by conducting reverse current above its specified Zener breakdown threshold. Its low 20 Ω dynamic impedance ensures minimal voltage variation under load changes, and its 25 °C/W junction-to-lead thermal resistance supports reliable operation up to 5 W when mounted with ≥10 mm lead length from body.
The 1N5367AE3/TR13 exhibits 0.5 μA maximum reverse leakage at 32.7 V (VR = 0.75 × VZ), 1.2 V forward voltage at 1.0 A, and withstands 190 A non-repetitive surge current (8.3 ms half-sine). Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 43 V nominal, ±10% tolerance - defines regulated output voltage under specified test current |
| Test Current (IZT) | 30 mA - operating point where VZ and ZZ are guaranteed per JEDEC spec |
| Dynamic Impedance (ZZ) | 20 Ω max - determines voltage stability against current fluctuations in regulation loop |
| Max Reverse Current (IR) | 0.5 μA at VR = 32.7 V - ensures low standby power loss in high-impedance bias networks |
| Max Zener Current (IZM) | 190 mA - maximum continuous DC current before thermal runaway at TL = 25°C |
| Thermal Resistance (RθJL) | 25 °C/W junction-to-lead - enables 5 W dissipation with ≤25°C temperature rise above lead temperature |
| Surge Current (IZSM) | 190 A peak (8.3 ms half-sine) - supports transient overvoltage clamping without failure |
Pinout & Package
Package: Axial-leaded T-18 plastic case (Void-free UL94V-0 epoxy), cathode indicated by color band. Leads are RoHS-compliant annealed matte-tin plated, solderable per MIL-STD-750 Method 2026. Weight: 0.7 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference/ground node in shunt regulator configuration | Connected to system ground or lower-potential rail; reverse-biased operation requires cathode at higher potential |
| Cathode | Regulated output node | Banded end; connected to voltage node requiring stabilization; conducts reverse current to clamp excess voltage |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered 5 W Zener | Guaranteed performance per industry-standard test conditions (IZT, VZ, ZZ, IR) |
| ±10% voltage tolerance (A suffix) | Cost-optimized regulation accuracy suitable for non-critical reference and protection applications |
| RoHS-compliant (e3 suffix) | Lead-free matte-tin plating meets environmental compliance without sacrificing solderability |
| Tape-and-reel packaging (TR13) | Standard EIA-296 format enabling automated SMT placement despite axial form factor |
| Level 1 moisture sensitivity | No dry pack or baking required prior to assembly - reduces handling overhead and process risk |
Applications
| Power Supply Reference | Overvoltage Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5367B | ±5% tolerance (B suffix) vs. ±10% (A); otherwise identical electrical specs and package | Higher accuracy required in precision reference designs; tighter VZ distribution improves yield in calibrated systems | Select 1N5367B when ±5% regulation tolerance is mandatory; same thermal and surge ratings apply |
| MMBZ5263BS | Surface-mount SOD-123 package; 43 V, ±5%; 200 mW rating vs. 5 W; 30 Ω ZZ | Low-power portable or space-constrained applications; unsuitable for >200 mW continuous dissipation | Choose MMBZ5263BS only for PCB area-limited designs with <100 mA average current; not a drop-in replacement |
Compared with 1N5367AE3/TR13, the 1N5367B offers tighter voltage tolerance for improved reference accuracy without changing layout or thermal design, while the MMBZ5263BS trades power handling and axial mounting for miniaturization - requiring full requalification for thermal and surge performance.

FAQ
What is the Zener voltage tolerance of the 1N5367AE3/TR13?
The 1N5367AE3/TR13 has a ±10% Zener voltage tolerance, indicated by the "A" suffix in its part number. This means its nominal 43 V breakdown voltage is guaranteed between 38.7 V and 47.3 V at 30 mA test current and 25°C lead temperature. The e3 suffix confirms RoHS compliance, and TR13 denotes EIA-296 tape-and-reel packaging.
Can the 1N5367AE3/TR13 be used in surface-mount designs?
The 1N5367AE3/TR13 is an axial-leaded T-18 package and is not inherently surface-mount compatible. However, it can be manually mounted on through-hole pads or adapted using axial-to-SMT adapter carriers. For native SMT implementation, consider Microsemi's SMBJ5367B or ON Semiconductor's 1N5367BRLG - both require layout redesign due to differing footprints and thermal paths.
What is the maximum power dissipation of the 1N5367AE3/TR13 at 75°C ambient?
At 75°C ambient, the 1N5367AE3/TR13 must be derated per its thermal resistance curve. With RθJA = 85°C/W on FR4 (1 oz Cu, 4 mm² pad), usable power drops to ~2.2 W. For full 5 W operation, lead temperature must remain ≤25°C - achieved via heatsinking or short leads (≤10 mm) to maintain RθJL = 25°C/W. Derating data is shown in Figure 1 of the Microsemi datasheet.
How does the 1N5367AE3/TR13 handle surge currents?
The 1N5367AE3/TR13 is rated for 190 A peak non-repetitive surge current (IZSM) under an 8.3 ms half-sine waveform. This capability enables reliable overvoltage clamping in industrial transients without degradation. Its 25°C/W junction-to-lead thermal resistance helps absorb surge energy, and the UL94V-0 epoxy body provides mechanical robustness during high-current events.
Is the 1N5367AE3/TR13 suitable for automotive applications?
Yes - the 1N5367AE3/TR13 operates across –65°C to +150°C and meets MIL-PRF-19500 screening levels when ordered with MQ/MX/MV prefixes. Its nonsensitive ESD rating (MIL-STD-750 Method 1020), 0.5 μA leakage at 32.7 V, and 190 A surge rating make it appropriate for engine control unit (ECU) voltage supervision and infotainment power rail protection, provided thermal design accommodates 5 W dissipation.
