Product details
Overview
1N5358AE3/TR13 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal Zener voltage of 22 V, ±10% tolerance (A suffix), 50 mA test current, 3.5 Ω dynamic impedance at IZT, and maximum reverse current of 0.5 μA at 15.8 V. It regulates voltage in power supply reference and overvoltage protection circuits across industrial temperature range.
For engineers reviewing the 1N5358AE3/TR13 datasheet, 1N5358AE3/TR13 pinout, 1N5358AE3/TR13 application, or 1N5358AE3/TR13 equivalent, key selection factors include its 22 V regulation point, ±10% tolerance, 5 W steady-state power capability at TL < 25°C, low 0.5 μA leakage at VR = 15.8 V, and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device operates as a two-terminal voltage reference where cathode (banded end) is biased positive relative to anode. Its Zener breakdown mechanism provides stable regulation over 10–500 mA operating current and −65°C to +150°C ambient range.
Thermal resistance is 25°C/W junction-to-lead at 3/8″ (10 mm) lead length, enabling 5 W dissipation with minimal heatsinking. Voltage regulation ΔVZ is specified as 0.45 V - the difference between VZ measured at 10% and 50% of IZM (75 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22 V nominal, ±10% tolerance - defines regulation setpoint for feedback loops and clamp thresholds |
| Test Current (IZT) | 50 mA - standardized bias point for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZ) | 3.5 Ω at IZT - determines output voltage deviation under load current changes |
| Max Reverse Current (IR) | 0.5 μA at VR = 15.8 V - ensures minimal leakage in high-impedance reference paths |
| Power Dissipation | 5.0 W at TL < 25°C - supports robust overvoltage clamping without external heatsink |
| Surge Current (IZSM) | 75 A (8.3 ms half-sine) - withstands transient energy in surge protection applications |
| Operating Temperature | −65°C to +150°C - suitable for automotive under-hood and industrial control environments |
Pinout & Package
Package: T-18 axial-leaded plastic case (void-free UL94V-0 epoxy), 0.7 g weight, cathode indicated by band. Leads are RoHS-compliant annealed matte-tin plated per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Positive terminal during Zener operation | Connected to regulated node or voltage clamp point; must be held at higher potential than anode |
| Anode (unbanded end) | Negative terminal during Zener operation | Typically tied to ground or lower-potential rail; completes current path through series resistor |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered 1N53xxB series | Industry-standard footprint and electrical behavior for drop-in compatibility across legacy designs |
| Moisture sensitivity Level 1 | No dry pack required - simplifies handling and eliminates bake-out before assembly |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Robust handling in manufacturing without special ESD controls |
| RoHS-compliant e3 suffix | Lead-free matte-tin plating meets EU Directive 2011/65/EU and J-STD-609 Class 1 |
| High surge current rating | 75 A peak (8.3 ms) enables use in transient voltage suppression without additional components |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5358B | Same 22 V nominal VZ, but ±5% tolerance (B suffix) and 50 mA IZT; identical package and thermal specs | Higher precision regulation required where ±5% VZ stability is critical for feedback accuracy | Select 1N5358B when tighter voltage tolerance is needed; otherwise 1N5358AE3/TR13 offers cost advantage with adequate performance |
| MMBZ5248BS-7-F | Surface-mount SOD-123 package, 22 V ±5%, 20 mA IZT, 500 mW power rating - not pin-compatible | Used in space-constrained PCB layouts where axial leads are impractical | Choose MMBZ5248BS-7-F only for new SMT designs; requires layout change and derates to 0.5 W vs. 5 W |
Compared with 1N5358B and MMBZ5248BS-7-F, the 1N5358AE3/TR13 delivers full 5 W power handling in axial form factor with ±10% tolerance - optimal for cost-sensitive, thermally demanding clamp and reference roles where moderate precision suffices.

FAQ
What is the Zener voltage tolerance of the 1N5358AE3/TR13?
The 1N5358AE3/TR13 has a Zener voltage tolerance of ±10%, indicated by the "A" suffix in its part number. Its nominal Zener voltage is 22 V, so the actual regulation range is 19.8 V to 24.2 V at 50 mA test current and 25°C lead temperature. This tolerance is confirmed in the manufacturer's electrical characteristics table and applies across the full operating temperature range.
Does the 1N5358AE3/TR13 require dry packing before PCB assembly?
No, the 1N5358AE3/TR13 does not require dry packing. It carries moisture sensitivity level (MSL) 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ambient conditions without baking prior to reflow soldering. This is explicitly stated in the Features section of the official Microsemi datasheet.
What is the maximum surge current rating for the 1N5358AE3/TR13?
The 1N5358AE3/TR13 has a maximum non-recurrent surge current (IZSM) rating of 75 A for an 8.3 ms half-sine waveform. This value is specified in the Electrical Characteristics table and reflects its capability to absorb transient energy in overvoltage protection applications without degradation.
Can the 1N5358AE3/TR13 be used as a direct replacement for the 1N5358B?
The 1N5358AE3/TR13 is not a direct replacement for the 1N5358B due to its wider ±10% voltage tolerance versus the 1N5358B's ±5%. While both share identical package, pinout, and thermal characteristics, substituting them may cause regulation drift beyond acceptable limits in precision feedback circuits. Verify system-level tolerance budget before interchange.
What is the forward voltage specification for the 1N5358AE3/TR13?
The forward voltage of the 1N5358AE3/TR13 is specified as a maximum of 1.2 V at 1.0 A forward current. This parameter appears in the Maximum Ratings section of the datasheet and is relevant for applications where the device may conduct in forward bias during startup or fault conditions.
