Product details

Overview

1PGSMC5358 from Taiwan Semiconductor is a surface-mount 5W Zener diode with nominal zener voltage 22V, 4mA test current, and 50Ω dynamic impedance at I_ZT, used for overvoltage protection in DC/DC converters and SMPS secondary-side regulation.

For engineers reviewing the 1PGSMC5358 datasheet, 1PGSMC5358 pinout, 1PGSMC5358 application, or 1PGSMC5358 equivalent, key selection criteria include its DO-214AB (SMC) package, 16.7V minimum zener voltage, 23.1V maximum zener voltage, 0.5μA leakage at 16.7V, and 216mA maximum DC zener current.

Technical Context

This single-die Zener diode operates within a -55°C to +175°C junction temperature range and delivers stable voltage regulation under transient overvoltage conditions. Its 20°C/W junction-to-lead thermal resistance supports reliable power dissipation when mounted on a 16mm × 16mm copper pad.

The device features photo-glass passivated junction for enhanced reliability and moisture sensitivity level 1 per J-STD-020, enabling standard reflow assembly without baking. Cathode band polarity marking ensures correct orientation during automated placement.

Key Specifications

Parameter	Value and Actual Design Meaning
V_Z (Nominal)	22 V - precise regulation point for mid-range voltage clamping
V_Z Range	20.9 V to 23.1 V - ±5% tolerance ensures predictable breakdown threshold
I_ZT	4 mA - standardized test current for consistent zener voltage measurement
Z_ZT	50 Ω - low dynamic impedance maintains regulation stability under load variation
P_D	5 W - continuous power handling capability at T_L = 75°C
I_ZM	216 mA - maximum DC zener current before thermal runaway risk
T_J Max	+175 °C - high-temperature operation suitable for enclosed power electronics

Pinout & Package

Package: DO-214AB (SMC), surface-mount, matte tin-plated leads, cathode indicated by band.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Current entry terminal in forward bias; reference node in reverse-bias clamping	Connected to lower-potential side of protected circuit; enables conduction when cathode exceeds anode by ≥V_Z
Cathode	Current exit terminal in forward bias; high-side clamp node in reverse bias	Connected to voltage rail requiring regulation; conducts during overvoltage to shunt excess current to ground or return path

Key Features

Feature	Design Value
Photo-glass passivated junction	Improves long-term stability and reduces parameter drift under thermal cycling and humidity exposure

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ22A (Bourns)	TVS diode, 22V standoff, 300W peak pulse power, bidirectional	Designed for transient suppression only; not rated for continuous DC regulation	Select when surge immunity dominates over steady-state regulation accuracy
1N5358B (ON Semiconductor)	Through-hole DO-201AD package, same 22V nominal, 5W rating, but higher Z_ZT (70Ω)	Requires PCB through-hole mounting; less suitable for high-density automated assembly	Select when legacy through-hole design or higher Z_ZT tolerance is acceptable

Compared with SMBJ22A and 1N5358B, the 1PGSMC5358 offers superior DC regulation precision (±5% V_Z, 50Ω Z_ZT) in a RoHS-compliant SMC package optimized for modern SMT lines-making it ideal for continuous-clamp roles where TVS devices lack DC stability and through-hole alternatives hinder miniaturization.
