Product details
Overview
SZMM5Z11VT5G from onsemi is a 11 V, ±5% tolerance Zener diode in SOD-523 package, rated for 500 mW steady-state power dissipation at 25 °C, with 20 Ω maximum Zener impedance at 5 mA test current and 0.1 μA reverse leakage at 8.0 V, used for precision voltage clamping and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the SZMM5Z11VT5G 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 maintain stable 11 V regulation across load variations. Its 20 Ω dynamic impedance at IZT = 5 mA ensures low output voltage deviation under transient current changes.
Designed for surface-mount assembly on FR-4 boards, it features 100% matte tin lead finish, MSL 1 rating, and 260 °C peak reflow tolerance. The −65 °C to +150 °C junction temperature range supports automotive and industrial ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11.0 V nominal, min 10.4 V / max 11.6 V at IZT = 5 mA - defines clamping threshold accuracy under standard test conditions. |
| Power Dissipation (PD) | 500 mW at TA = 25 °C, derated 4.0 mW/°C above - sets maximum continuous thermal load on standard FR-4 board. |
| Zener Impedance (ZZT) | 20 Ω max at IZT = 5 mA - determines AC voltage variation during dynamic current shifts in regulation circuits. |
| Reverse Leakage (IR) | 0.1 μA max at VR = 8.0 V - ensures minimal standby current in battery-powered systems. |
| ESD Rating | Class 3 (>16 kV) per Human Body Model - guarantees robustness against handling-induced electrostatic discharge. |
| Temperature Coefficient | +5.4 mV/°C - quantifies VZ drift with ambient temperature change, critical for stable operation across thermal ranges. |
| Capacitance | 130 pF max at VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering and signal integrity in RF-adjacent designs. |
Pinout & Package
SZMM5Z11VT5G is housed in a SOD-523 surface-mount package (1.20 mm × 0.80 mm × 0.60 mm body, 0.7 mm height), void-free thermosetting plastic case with 100% matte tin leads, qualified for MSL 1 and 260 °C reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Banded End) | Cathode | Connected to regulated output node; polarity band identifies cathode for correct PCB orientation and reverse-bias connection. |
| 2 | Anode | Connected to ground or lower-potential reference; completes reverse-bias path enabling Zener conduction at breakdown voltage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 Qualified | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock per JESD47. |
| Pb-Free & RoHS Compliant | Meets EU RoHS Directive 2011/65/EU and JEDEC JS709E; compatible with lead-free soldering processes. |
| High ESD Robustness | Withstands >16 kV HBM - eliminates need for external ESD protection in handheld interface circuits. |
| Miniature SOD-523 Footprint | 1.20 mm × 0.80 mm area - enables placement in tight spaces such as smartphone camera modules and wearable sensor nodes. |
| Stable Low-Tempco Regulation | +5.4 mV/°C tempco - minimizes voltage drift over −40 °C to +125 °C operating range in automotive infotainment systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C11LT1G | Same 11 V nominal, ±5% tolerance, but SOD-323 package (1.7 mm × 1.3 mm) - 42% larger footprint and 300 mW PD. | Limited to non-space-critical industrial controls; not suitable for ultra-thin mobile PCBs requiring SOD-523 density. | Select when higher power margin (300 mW vs. 500 mW) is prioritized over board area, or legacy SOD-323 layout reuse is required. |
| MMSZ5242BT1G | 12 V nominal, ±5% tolerance, SOD-123 package (3.7 mm × 1.6 mm), 500 mW rating, 30 Ω ZZT - higher impedance and 1 V higher VZ. | Used where 12 V clamping is acceptable and board space allows larger SOD-123; less precise regulation than SZMM5Z11VT5G. | Choose only if system design tolerates 12 V threshold and requires broader vendor availability; not a direct functional substitute for 11 V requirement. |
Compared with BZX584C11LT1G and MMSZ5242BT1G, SZMM5Z11VT5G offers the smallest footprint among 11 V Zeners, highest power rating in SOD-523, and lowest ZZT, making it optimal for miniaturized, high-reliability applications demanding exact 11 V clamping.
