Product details
Overview
1PGSMB5930H from Taiwan Semiconductor is a surface-mount silicon Zener diode with nominal zener voltage 16 V, 3 W power rating, 23.4 Ω dynamic impedance at 10 mA test current, and DO-214AA (SMB) package. It provides precise voltage regulation and reference in automotive and industrial power supply circuits.
For engineers reviewing the 1PGSMB5930H datasheet, 1PGSMB5930H pinout, 1PGSMB5930H application, or 1PGSMB5930H equivalent, key selection criteria include zener voltage tolerance (±5%), junction temperature range (–55°C to +175°C), thermal resistance (RθJA = 59°C/W), AEC-Q101 qualification, and moisture sensitivity level (MSL 1).
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load and line conditions. Its photo-glass passivated junction ensures long-term stability and low leakage (<1 μA at 12.2 V), while the DO-214AA package supports automated placement and delivers low inductance for transient suppression.
The device is rated for 3 W total power dissipation at 75°C lead temperature, with derating above that point. Thermal performance is characterized by RθJL = 21°C/W and RθJC = 23°C/W on a 10 mm × 10 mm copper pad PCB, enabling reliable operation in high-temperature environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A (Bourns) | TVS diode, 16 V standoff, 24.4 V clamping at 10 A, unidirectional, 600 W peak pulse power | Designed for transient suppression, not precision regulation; higher clamping voltage, no tight VZ tolerance | Select when surge immunity (IEC 61000-4-5) is primary need; not suitable as voltage reference |
| 1N5925B (ON Semiconductor) | Through-hole DO-41, 16 V, 3 W, ±5%, ZZT = 23 Ω at 10 mA, MSL not specified | Lacks AEC-Q101 qualification and MSL 1 rating; incompatible with SMT assembly lines requiring moisture-safe components | Choose for cost-sensitive non-automotive prototypes where manual assembly or legacy board design applies |

FAQ
What is the exact zener voltage tolerance for 1PGSMB5930H?
The 1PGSMB5930H has a nominal zener voltage of 16 V with a tolerance of ±5%, meaning the actual VZ falls between 15.20 V and 16.80 V at IZT = 10 mA and TA = 25°C. This tolerance is confirmed in the Electrical Specifications table on page 2 of the official datasheet (Version A2102).
Is 1PGSMB5930H suitable for automotive applications?
Yes, the 1PGSMB5930H is AEC-Q101 qualified, making it suitable for automotive applications including engine control units, body electronics, and infotainment power rails. Its operating junction temperature range (–55°C to +175°C) and MSL 1 rating further support under-hood and chassis-mounted use cases.
What is the maximum DC zener current for 1PGSMB5930H?
The maximum DC zener current (IZM) for 1PGSMB5930H is 94 mA, derived from Ptot = 3 W and VZ = 16 V (I = P/V). This value is explicitly listed in the Electrical Specifications table and assumes thermal equilibrium on a 10 mm × 10 mm Cu pad PCB.
Does 1PGSMB5930H have a defined junction-to-ambient thermal resistance?
Yes, the junction-to-ambient thermal resistance (RθJA) for 1PGSMB5930H is 59°C/W when mounted on a standard 10 mm × 10 mm copper pad test board. This value is critical for calculating allowable power dissipation at elevated ambient temperatures.
What marking code identifies 1PGSMB5930H on the device body?
The 1PGSMB5930H is marked with the code "P930B" on its package body. This marking appears adjacent to the cathode band and is consistent across all units in the series per the Ordering Information section of the datasheet.
