Product details
Overview
SZMM5Z16VT5GF from Nexperia is a 16 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 11.2 Ω differential resistance at IZ = 1 mA and 10.4–14.0 mV/K temperature coefficient. It serves as a precision voltage reference or shunt regulator in low-power automotive and industrial bias circuits.
For engineers reviewing the SZMM5Z16VT5GF datasheet, SZMM5Z16VT5GF pinout, SZMM5Z16VT5GF application, or SZMM5Z16VT5GF equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (Rth(j-sp) = 65 K/W), AEC-Q101 qualification, and ultra-small SOD523 footprint for space-constrained PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load or supply conditions. Its 16 V nominal Zener voltage is specified at IZ = 1 mA with ±2 % tolerance, and exhibits low dynamic impedance (11.2 Ω) ensuring minimal voltage deviation during current transients.
Designed for automotive-grade reliability, it meets AEC-Q101 stress test requirements and features a junction-to-solder-point thermal resistance of 65 K/W when mounted on FR4 PCB with 35 mm² copper area-enabling robust thermal performance in high-temperature ambient environments up to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.68 V to 16.32 V at IZ = 1 mA - defines precise regulation point for feedback or reference circuits |
| Tolerance | ±2 % - ensures tight voltage accuracy without post-production trimming |
| Differential Resistance (rdiff) | 11.2 Ω at IZ = 1 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 µs square wave - supports transient surge suppression in ESD-coupled lines |
| Temperature Coefficient (SZ) | 10.4 to 14.0 mV/K - quantifies voltage drift over temperature, critical for stable operation from −55 °C to +150 °C |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables use in under-hood automotive and industrial control modules |
Pinout & Package
The SZMM5Z16VT5GF uses a 2-pin SOD523 (SC-79) surface-mount plastic package with cathode marked by a bar on the device body. The compact 1.25 mm × 0.85 mm footprint supports high-density routing in portable and automotive electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated voltage node; marking bar identifies this terminal for correct PCB orientation |
| 2 (A) | Anode | Connected to ground or lower-potential rail; reverse-biased configuration enables Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics |
| Ultra-small SOD523 package | 1.25 mm × 0.85 mm footprint reduces board area by >50% vs. SOD-123, enabling miniaturized designs |
| Low differential resistance | 11.2 Ω at 1 mA ensures <112 mV output shift per 10 mA load change-critical for stable reference generation |
| Wide operating temperature range | −55 °C to +150 °C ambient rating supports deployment in harsh under-hood or industrial environments |
| Controlled temperature coefficient | 10.4–14.0 mV/K allows predictable voltage drift compensation in analog sensor signal chains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C16 | Same 16 V nominal, ±5 % tolerance, SOD-523 package, but higher rdiff (25 Ω) and no AEC-Q101 qualification | Limited to commercial-grade consumer products; unsuitable for automotive or extended-temperature industrial use | Select only if cost is primary constraint and AEC-Q101 compliance is not required |
| MMSZ5245B | 16 V nominal, ±5 % tolerance, SOD-123 package, 350 mW Ptot, rdiff = 17 Ω, no AEC-Q101 rating | Larger footprint (2.7 mm × 1.4 mm) and wider tolerance reduce suitability for space- and accuracy-critical designs | Choose only when board layout permits larger package and ±5 % tolerance is acceptable |
Compared with BZX584-C16 and MMSZ5245B, SZMM5Z16VT5GF delivers tighter ±2 % voltage accuracy, lower 11.2 Ω dynamic impedance, and automotive-qualified reliability in the smallest SOD523 footprint-making it optimal for high-precision, high-reliability embedded systems.

FAQ
What is the maximum continuous forward current for SZMM5Z16VT5GF?
The device is rated for a maximum forward current (IF) of 200 mA per Absolute Maximum Ratings. However, in normal Zener operation, it functions in reverse bias; forward conduction is limited to brief pulses (≤300 µs) with typical VF ≤ 1.1 V at 100 mA, making it unsuitable for sustained forward-current applications.
How does the 65 K/W junction-to-solder-point thermal resistance impact PCB layout?
Rth(j-sp) = 65 K/W means that with 100 mW power dissipation, the junction-to-solder-point temperature rise is ~6.5 °C-enabling reliable operation without thermal vias when using the recommended 35 mm² copper area at the cathode pad. This simplifies layout for ultra-thin or multi-layer boards.
Is SZMM5Z16VT5GF suitable for ESD protection in addition to voltage regulation?
No-it is not designed or rated for ESD clamping. While it withstands 40 W non-repetitive surges (100 µs), its 16 V Zener voltage and lack of specified IEC 61000-4-2 parameters make it inappropriate for dedicated ESD protection. Use purpose-built TVS diodes like PESD5V0S1BA for such roles.
Can SZMM5Z16VT5GF replace older Zener diodes like 1N4744A in existing designs?
Only with layout and thermal validation. SZMM5Z16VT5GF has identical 16 V nominal voltage but differs critically: SOD523 vs. DO-41 package, 300 mW vs. 1 W power rating, and ±2 % vs. ±5 % tolerance. Direct replacement requires verifying thermal margin, footprint compatibility, and whether tighter tolerance improves or destabilizes the circuit.
