Product details
Overview
1PGSMC5361 from Taiwan Semiconductor is a 5 W, 27 V nominal Zener diode in DO-214AB (SMC) package, designed for voltage regulation and overvoltage protection in DC/DC converters, SMPS, and lighting circuits. It features 5% voltage tolerance, 5 mA test current, 50 Ω dynamic impedance at IZT, and operates across –55°C to +175°C junction temperature range.
For engineers reviewing the 1PGSMC5361 datasheet, 1PGSMC5361 pinout, 1PGSMC5361 application, or 1PGSMC5361 equivalent, key selection factors include its 27 V ±5% Zener voltage, 5 W power rating, low 50 Ω ZZT, 0.5 μA leakage at 20.6 V, and DO-214AB surface-mount compatibility with automated placement.
Technical Context
This single-die Zener diode uses photo-glass passivated junction technology for stable breakdown characteristics and low inductance. Its thermal design supports 20°C/W junction-to-lead resistance when mounted on a 16 mm × 16 mm copper pad, enabling reliable operation up to 175°C junction temperature.
The device complies with J-STD-020 Level 1 moisture sensitivity, JESD201 Class 2 whisker resistance, and RoHS/halogen-free requirements per IEC 61249-2-21. Polarity is marked by a cathode band on the DO-214AB case.

IC Role / Device Role / Timing Role: Zener-based feedback reference or post-regulator clamp in low-cost, non-isolated output stages. Use Value: DO-214AB package allows automated placement; 5 W rating handles sustained overloads without derating beyond 75°C lead temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ27A (Bourns) | TVS diode, 27 V standoff, 400 W peak pulse power, bidirectional | Designed for ESD/surge suppression, not precision DC regulation | Select only if transient protection-not stable voltage reference-is the primary requirement |
| 1N5361B (ON Semiconductor) | 27 V Zener, 5 W, DO-201AD package (axial lead), higher RθJA (75°C/W) | Through-hole mounting; less suitable for high-density SMT designs | Prefer 1PGSMC5361 for space-constrained PCBs requiring automated assembly and superior thermal performance |
Compared with SMBJ27A and 1N5361B, the 1PGSMC5361 delivers optimized DC regulation accuracy, lower thermal resistance in SMT form, and tighter process control for consistent VZ distribution-making it preferred for precision shunt references in modern power supplies.

FAQ
What is the nominal Zener voltage and tolerance of the 1PGSMC5361?
The 1PGSMC5361 has a nominal Zener voltage of 27 V with a ±5% tolerance, specified as 25.65 V (min) to 28.35 V (max) at a test current of 5 mA. This tolerance is confirmed in the Electrical Specifications table of the official TSC datasheet Version D2102 and applies directly to the 1PGSMC5361 device marking code P361B.
What is the maximum power dissipation and thermal derating behavior of the 1PGSMC5361?
The 1PGSMC5361 is rated for 5 W DC power dissipation at a lead temperature (TL) of 75°C, measured on a 16 mm × 16 mm copper pad test board. Above 75°C, power must be linearly derated at 0.05 W/°C, reaching zero at 175°C. This derating curve is defined in the Absolute Maximum Ratings section of the TSC datasheet for 1PGSMC5361.
Does the 1PGSMC5361 have a specified Zener impedance, and what does it mean for circuit design?
Yes, the 1PGSMC5361 has a typical Zener impedance (ZZT) of 50 Ω at 5 mA test current. This value reflects the dynamic resistance in the breakdown region and directly impacts regulation accuracy under varying load currents - lower ZZT yields smaller output voltage variation, making the 1PGSMC5361 suitable for applications demanding stable reference voltages in SMPS feedback loops.
What is the leakage current specification for the 1PGSMC5361, and at what reverse voltage is it measured?
The 1PGSMC5361 specifies a maximum leakage current (IR) of 0.5 μA at a reverse voltage (VR) of 20.6 V. This low leakage ensures minimal power loss in standby or light-load conditions, supporting energy-efficient designs such as battery-backed lighting controllers or always-on adapter outputs where quiescent current matters.
Is the 1PGSMC5361 compatible with standard SMT reflow processes, and what is its moisture sensitivity level?
Yes, the 1PGSMC5361 is rated at J-STD-020 Moisture Sensitivity Level 1, meaning it can be subjected to unlimited floor life and standard reflow profiles without pre-baking. Its DO-214AB (SMC) package with matte tin-plated leads meets J-STD-002 solderability requirements, ensuring reliable joint formation in automated assembly lines handling the 1PGSMC5361.
