Product details
Overview
1PGSMB5928H from Taiwan Semiconductor is a surface-mount silicon Zener diode with nominal zener voltage 13 V, 3 W power rating, 28.8 mA test current, and DO-214AA (SMB) package. It delivers stable voltage regulation in automotive-grade circuits requiring AEC-Q101 qualification, low-inductance operation, and moisture-insensitive packaging.
For engineers reviewing the 1PGSMB5928H datasheet, 1PGSMB5928H pinout, 1PGSMB5928H application, or 1PGSMB5928H equivalent, key selection criteria include zener voltage tolerance (±5%), thermal resistance (RθJA = 59 °C/W), junction temperature range (–55 to +175 °C), and compliance with JESD201 Class 2 whisker testing.
Technical Context
This single-die Zener diode operates in reverse-bias breakdown mode to maintain precise DC reference voltages under varying load and temperature conditions. Its photo-glass passivated junction ensures long-term stability and reliability in harsh environments.
The device supports automated SMT placement and meets UL 94V-0 flammability requirements. With a cathode band polarity indicator and matte tin-plated leads compliant to J-STD-002, it enables robust solder joint formation on PCBs with 10 mm × 10 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.35–13.65 V at IZT = 28.8 mA - tight ±5% tolerance enables accurate voltage referencing without external trimming |
| Power Dissipation (Ptot) | 3 W at TL = 75 °C - derates linearly above 75 °C per 21 mW/°C on 10 mm × 10 mm Cu pad |
| Junction Temperature Range | –55 to +175 °C - supports operation in under-hood automotive and industrial power supply environments |
| Zener Impedance (ZZT) | 7.0 Ω at IZT = 28.8 mA - low dynamic impedance ensures minimal output voltage variation under load transients |
| Leakage Current (IR) | ≤ 1 μA at VR = 9.9 V - guarantees negligible standby power loss in battery-backed reference circuits |
| Thermal Resistance (RθJA) | 59 °C/W - defines maximum ambient temperature rise for safe 3 W operation on standard FR-4 PCB |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | TVS diode with 13 V standoff, 200 W peak pulse power, higher leakage (>5 μA) | Designed for transient suppression, not precision regulation | Select only if surge immunity > regulation accuracy is primary requirement |
| BZX84-C13 | SOT-23 package, 300 mW rating, ±5% tolerance, RθJA ≈ 300 °C/W | Lower power handling and thermal performance limits use to low-current references | Choose for space-constrained, low-power designs where SMB footprint is unavailable |
