Product details
Overview
SZMM5Z11VT5GF from Nexperia is a 11 V ±2 % tolerance Zener diode in SOD523 (SC-79) package, rated for 300 mW total power dissipation and 40 W non-repetitive peak reverse power, with 0.1 Ω typical differential resistance at IZ = 5 mA and AEC-Q101 qualification for automotive voltage regulation.
For engineers reviewing the SZMM5Z11VT5GF datasheet, SZMM5Z11VT5GF pinout, SZMM5Z11VT5GF application, or SZMM5Z11VT5GF equivalent, this device serves as a precision shunt regulator in low-power biasing, overvoltage clamping, and reference voltage generation where tight voltage tolerance, low thermal drift, and ultra-small footprint are required.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 11 V reference across its terminals under controlled current conditions (IZ = 5 mA), with temperature coefficient of +5.4 mV/K and junction-to-solder-point thermal resistance of 65 K/W for reliable thermal performance on FR4 PCBs.
Its SC-79 package enables high-density placement in space-constrained designs, while AEC-Q101 qualification confirms suitability for automotive ambient temperature ranges (−40 °C to +150 °C) and transient surge robustness per IEC 60134 limiting values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.78 V to 11.22 V at IZ = 5 mA - defines precise regulation window for reference stability |
| Tolerance | ±2 % - ensures predictable voltage accuracy without post-production trimming |
| Differential Resistance (rdiff) | 0.1 Ω max at IZ = 5 mA - minimizes output voltage variation under load current changes |
| Total Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C on FR4 with 35 mm² copper - sets continuous operating limit for thermal design |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W at tp = 100 µs - supports transient overvoltage suppression without failure |
| Reverse Current (IR) | ≤150 µA at VR = 8.0 V - guarantees low leakage in standby or high-impedance sensing circuits |
| Thermal Resistance (Rth(j-sp)) | 65 K/W - enables accurate junction temperature estimation from solder point measurement |
Pinout & Package
The SZMM5Z11VT5GF uses a 2-pin SOD523 (SC-79) surface-mount plastic package with cathode marked by a bar on the top surface. The package measures 1.25 mm × 0.85 mm × 0.65 mm and is optimized for reflow soldering on fine-pitch PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; marking bar identifies this terminal for correct orientation during placement |
| 2 (A) | Anode | Connected to ground or lower potential reference; forms reverse-biased junction for Zener operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C11 | Same 11 V nominal, ±2 %, but SOD323 package (larger footprint, 1.7 mm × 1.3 mm) | Higher thermal resistance (Rth(j-a) = 450 K/W vs. 350 K/W) reduces power handling in confined layouts | Select when legacy layout compatibility or higher surge margin (500 mW Ptot) outweighs size constraints |
| MMSZ5240B | 11 V, ±5 % tolerance, SOD123 package, 500 mW Ptot, no AEC-Q101 qualification | Larger footprint (2.9 mm × 1.9 mm) and wider tolerance increase calibration burden in precision systems | Choose only for cost-sensitive industrial applications where automotive qualification and tight tolerance are unnecessary |
Compared with BZX584C11 and MMSZ5240B, SZMM5Z11VT5GF delivers superior space efficiency, tighter voltage control, and guaranteed automotive reliability-making it optimal for next-generation compact, safety-aware electronics where board area and specification compliance are non-negotiable.

FAQ
What is the maximum continuous reverse current this Zener can sustain at 11 V?
The SZMM5Z11VT5GF is not rated for continuous reverse current at full Zener voltage; instead, it is specified for regulated operation at IZ = 5 mA (typical test condition). At that current, power dissipation is 55 mW - well within its 300 mW total limit. Sustained operation above 5 mA requires thermal derating per Rth(j-a) = 350 K/W and ambient temperature constraints.
How does the +5.4 mV/K temperature coefficient affect long-term voltage stability?
The +5.4 mV/K coefficient means output voltage increases by ~5.4 mV per °C rise in junction temperature. Over a −40 °C to +125 °C range, this yields ~0.89 V total drift - compensated in precision designs via external resistor networks or digital calibration. Its predictability enables deterministic system-level compensation.
Can this Zener be used in parallel for higher power handling?
No - Zener diodes exhibit manufacturing variations in VZ and rdiff, causing current imbalance when paralleled. Even with matched units, thermal runaway risk remains due to positive temperature coefficient. For higher power, use a single higher-rated device or active regulation with a transistor-based shunt.
Is the SOD523 package compatible with standard reflow profiles for lead-free assembly?
Yes - Nexperia specifies compatibility with IPC/JEDEC J-STD-020D reflow profiles. The recommended peak temperature is 260 °C for ≤30 seconds, with ramp rates ≤3 °C/s pre-peak. Figure 10 in the datasheet provides exact solder land dimensions and paste volume guidance for reliable attachment.
