Product details
Overview
SZMM5Z13VT5G from onsemi is a 13 V ±5% Zener diode in SOD-523 package, rated for 500 mW steady-state power dissipation at 25 °C, with 30 Ω maximum Zener impedance at 5 mA test current and 7.0 μA reverse leakage at 10.4 V, used for precision voltage regulation and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the SZMM5Z13VT5G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (250 °C/W), ESD rating (>16 kV HBM), AEC-Q101 qualification, and SOD-523 footprint compatibility with high-density PCB layouts.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to clamp voltage at nominal 13 V with temperature coefficient of ±7.0 mV/°C. It delivers stable regulation under DC or low-frequency transient conditions with 120 pF junction capacitance at 0 V bias and 1 MHz frequency.
Designed for surface-mount use on FR-4 boards, it supports reflow soldering up to 260 °C and meets MSL 1 moisture sensitivity requirements. Its cathode-anode polarity is marked by a band on the SOD-523 body, and it achieves Class 3 ESD robustness without external protection circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C13LT1G | Same 13 V nominal, ±5% tolerance, but SOD-323 package (1.7 × 1.3 mm) - 42% larger footprint | Higher power handling (500 mW same), but lower ESD rating (8 kV HBM vs. >16 kV) | Select when board layout allows larger pad spacing and ESD immunity is less critical than cost |
| MMSZ5242BT1G | 13 V nominal, ±5%, but SOD-123 package (3.7 × 1.6 mm) - 3.7× larger area, 500 mW rating | No AEC-Q101 qualification; not automotive-grade; higher thermal resistance (300 °C/W) | Choose for non-automotive industrial use where board space is unconstrained and qualification is not required |
Compared with BZX584C13LT1G and MMSZ5242BT1G, SZMM5Z13VT5G offers the smallest footprint, highest ESD robustness, and automotive qualification - making it optimal for next-gen portable and vehicular systems where size, reliability, and compliance are co-prioritized.
