Product details
Overview
1N5358E3/TR13 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 22 V, ±5% tolerance (B-suffix equivalent), 50 mA test current, 3.5 Ω maximum dynamic impedance at IZT, and 0.5 μA maximum reverse leakage at 17.6 V. It operates from –65 °C to +150 °C and is used for precision voltage reference and overvoltage protection in power supply feedback loops.
For engineers reviewing the 1N5358E3/TR13 datasheet, 1N5358E3/TR13 pinout, 1N5358E3/TR13 application, or 1N5358E3/TR13 equivalent, key selection criteria include Zener voltage stability under varying load current, thermal resistance (25 °C/W junction-to-lead), surge current rating (4.7 A peak), 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. Its regulation performance is defined by ΔVZ = 0.45 V (difference between voltages at 10% and 50% of IZM), ZZK = 216 Ω at 1 mA, and tight voltage control across 50 mA to 750 mA operating range when adequately heat-sunk.
The 1N5358E3/TR13 uses a void-free thermosetting epoxy T-18 package with cathode band marking, rated for 260 °C soldering (10 s), and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22 V ±5% - stable reference point for feedback networks requiring <±1.1 V deviation over temperature and life. |
| Test Current (IZT) | 50 mA - defines the operating point where VZ and dynamic impedance are specified; typical bias for linear regulator references. |
| Max Dynamic Impedance (ZZ) | 3.5 Ω at IZT - low AC impedance ensures minimal output voltage variation under dynamic load transients. |
| Max Reverse Leakage (IR) | 0.5 μA at 17.6 V - enables low-power standby operation without significant quiescent current loss. |
| Max Regulator Current (IZM) | 75 mA - maximum continuous DC current at 25 °C lead temperature; derates linearly above 25 °C per Figure 1. |
| Surge Current (IZSM) | 4.7 A (8.3 ms half-sine) - withstands transient overvoltage events such as ESD or inductive kickback without failure. |
| Thermal Resistance (RθJL) | 25 °C/W junction-to-lead (3/8″ lead length) - supports 5 W dissipation with modest heatsinking on PCB leads. |
Pinout & Package
T-18 axial-leaded plastic package (void-free UL94V-0 epoxy); cathode identified by single black band; leads plated with RoHS-compliant annealed matte tin per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reverse-biased reference terminal | Connected to circuit ground or lower-potential node; forms reference node with cathode at regulated voltage. |
| Cathode | Regulated output terminal | Banded end; held at precise 22 V relative to anode during reverse conduction; feeds error amplifier inputs or clamp nodes. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered Zener series | Ensures standardized electrical behavior and interchangeability across qualified suppliers and legacy designs. |
| RoHS-compliant e3 suffix | Meets EU Directive 2011/65/EU with matte-tin plating; eliminates lead-based solder compatibility concerns. |
| Level 1 moisture sensitivity | Zero dry-pack requirement simplifies handling, storage, and SMT reflow prep-no baking needed before assembly. |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Withstands human-body-model ESD events without parameter shift or failure-reduces test screening overhead. |
| High surge current rating | 4.7 A non-recurrent half-sine capability protects downstream circuitry from line transients and switching spikes. |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp Circuit |
|---|---|
Use Scenario: Used in the optocoupler feedback path of isolated DC-DC converters to regulate output voltage within ±1%. IC Role / Device Role / Timing Role: Provides precise 22 V reference to TL431 shunt regulator or directly biases error amplifier input. Use Value: Low ΔVZ (0.45 V) and 3.5 Ω ZZ minimize output voltage drift across line/load/temperature variations. | Use Scenario: Placed across MOSFET drain-source or relay coil to suppress inductive kickback exceeding 22 V. IC Role / Device Role / Timing Role: Acts as passive clamping element diverting surge energy to ground before voltage exceeds safe threshold. Use Value: 4.7 A surge rating and 25 °C/W RθJL enable reliable absorption of 8.3 ms transients without thermal runaway. |
| Programmable Voltage Reference | Industrial Sensor Excitation |
Use Scenario: Paired with resistive dividers to generate stable sub-22 V references (e.g., 5 V, 12 V) for ADC biasing or DAC calibration. IC Role / Device Role / Timing Role: Serves as primary Zener source in buffered reference design; drives high-impedance op-amp inputs. Use Value: ±5% tolerance and low ZZK (216 Ω at 1 mA) ensure accuracy and stability even at microampere bias currents. | Use Scenario: Supplies excitation voltage to strain gauges or RTDs in harsh-environment measurement systems. IC Role / Device Role / Timing Role: Delivers regulated 22 V bias independent of supply rail fluctuations in 24 V industrial buses. Use Value: –65 °C to +150 °C operating range and 0.5 μA leakage at 17.6 V maintain signal integrity in extended-temperature enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5358B | Same 22 V ±5%, 5 W rating, but with SnPb (non-RoHS) plating and no e3 suffix. | Not suitable for RoHS-compliant production; requires leaded solder process. | Select only if legacy SnPb assembly is mandated and environmental compliance is not required. |
| SMBJ5358B | Surface-mount SMB package; identical electrical specs but 85 °C/W RθJA vs. 25 °C/W RθJL. | Requires PCB copper area for thermal management; unsuitable for through-hole or lead-heatsink mounting. | Choose for space-constrained layouts where automated placement is preferred and thermal pad design is feasible. |
Compared with 1N5358B and SMBJ5358B, the 1N5358E3/TR13 uniquely combines RoHS compliance, axial-leaded mechanical robustness, and superior junction-to-lead thermal performance-making it optimal for industrial power supplies requiring field-replaceable, high-surge-tolerance references.

FAQ
What is the Zener voltage tolerance of the 1N5358E3/TR13?
The 1N5358E3/TR13 has a nominal Zener voltage of 22 V with ±5% tolerance, as indicated by the "B"-equivalent suffix in the 1N53xxB family. This means the actual measured VZ falls between 20.9 V and 23.1 V at 50 mA and 25 °C lead temperature. The e3 suffix confirms RoHS compliance but does not alter voltage tolerance.
Does the 1N5358E3/TR13 require dry packing before PCB assembly?
No, the 1N5358E3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it may be stored and assembled without dry packing or baking. Its void-free epoxy T-18 package inherently limits moisture ingress, eliminating preconditioning steps required for higher-level devices.
What is the maximum continuous current the 1N5358E3/TR13 can handle at 25 °C?
The 1N5358E3/TR13 supports a maximum continuous Zener current (IZM) of 75 mA at 25 °C lead temperature (TL). This value assumes 3/8″ (10 mm) lead length from body; derating begins linearly above 25 °C per the power derating curve in Microsemi's datasheet Figure 1.
Can the 1N5358E3/TR13 be used as a direct replacement for the 1N5358B?
Yes, the 1N5358E3/TR13 is functionally and electrically identical to the 1N5358B except for RoHS-compliant matte-tin plating (vs. SnPb) and tape-and-reel packaging (TR13). No circuit or layout changes are needed, but solder process must match the e3 finish-lead-free reflow profiles apply.
What is the surge current rating of the 1N5358E3/TR13 and how is it defined?
The 1N5358E3/TR13 has a maximum non-recurrent surge current (IZSM) of 4.7 A, defined as the peak amplitude of an 8.3 ms half-sine waveform. This rating reflects its ability to absorb transient energy-such as inductive flyback or ESD-without parametric shift or catastrophic failure, provided the device is within its thermal limits.
