Product details
Overview
HZM6.2ZMFATL-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits. It delivers a nominal zener voltage of 6.2 V (B3 grade: 6.26–6.53 V), with dynamic resistance of 50 Ω at 5 mA test current, maximum power dissipation of 200 mW, and operates within –55°C to +150°C storage temperature range. It is commonly used in voltage regulation for sensor biasing, ADC reference trimming, and power supply feedback networks.
For engineers reviewing the HZM6.2ZMFATL-E datasheet, HZM6.2ZMFATL-E pinout, HZM6.2ZMFATL-E application, or HZM6.2ZMFATL-E equivalent, key selection considerations include its MPAK package footprint, 2 µA reverse leakage at VR = 3.0 V, ±2% zener voltage tolerance (B3 grade), thermal coefficient of +0.04 mV/°C near 6.2 V, and suitability for high-density SMT layouts requiring stable low-current regulation.
Technical Context
This device functions as a two-terminal shunt voltage regulator, operating in reverse breakdown mode with controlled zener knee characteristics. Its epitaxial planar construction ensures tight voltage distribution across production lots and stable performance under pulsed test conditions (Pw = 40 ms).
The HZM6.2ZMFATL-E exhibits a positive temperature coefficient (+0.04 mV/°C) near its nominal 6.2 V rating, enabling predictable drift compensation in temperature-sensitive references. It is rated for 2 µA maximum reverse current at 3.0 V and supports up to 5 mA zener test current without exceeding 200 mW power limit at 25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.26–6.53 V at IZ = 5 mA - defines stable regulation point for low-noise reference design |
| Dynamic Resistance (rd) | 50 Ω max at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 200 mW max at Ta = 25°C - sets absolute thermal limit for continuous operation on standard FR-4 PCB |
| Reverse Current (IR) | 2 µA max at VR = 3.0 V - indicates low leakage for battery-powered or high-impedance bias networks |
| Junction Temperature (Tj) | 150°C max - enables use in industrial environments with elevated ambient temperatures |
| Temperature Coefficient (γZ) | +0.04 mV/°C at ~6.2 V - provides predictable, low-drift behavior for precision analog references |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234B-7-F (Diodes Inc.) | Zener voltage 6.2 V (±5%), 200 mW, SOT-23 package, rd = 70 Ω | Higher dynamic resistance and wider tolerance; requires layout revision due to different pinout (Anode-Cathode-NC vs. NC-Anode-Cathode) | Select when SOT-23 footprint is already standardized and ±5% VZ tolerance is acceptable |
| BZX84-C6V2 (Nexperia) | Zener voltage 6.2 V (±5%), 350 mW, SOT-23, rd = 60 Ω, no NC pin | Higher power rating but lacks NC pin - incompatible with MPAK board space and requires redesign of keep-out zones | Choose for higher-power clamping where board area allows SOT-23 and NC pin functionality is unnecessary |
Compared with MMBZ5234B-7-F and BZX84-C6V2, the HZM6.2ZMFATL-E offers tighter B3-grade voltage tolerance (±2.2%), lower dynamic resistance (50 Ω), and an NC pin that simplifies layout isolation - making it preferable for precision reference and space-constrained MPAK designs.

FAQ
What is the zener voltage tolerance for HZM6.2ZMFATL-E?
The HZM6.2ZMFATL-E is specified in B3 grade, with a zener voltage range of 6.26 V to 6.53 V at 5 mA test current - corresponding to ±2.2% tolerance around the nominal 6.2 V rating. This tighter tolerance supports precision reference applications without external calibration, unlike broader-grade alternatives such as B1 or B2 variants in the same series.
Does HZM6.2ZMFATL-E have a no-connect (NC) pin, and how should it be handled?
Yes, HZM6.2ZMFATL-E has Pin 1 designated as NC (no connect). It is internally unconnected and must remain electrically floating - neither grounded nor routed. This NC pin enables improved isolation between anode and cathode terminals in high-impedance reference paths, and its presence distinguishes the MPAK package from standard SOT-23 Zeners like the BZX84-C6V2.
What is the maximum reverse leakage current for HZM6.2ZMFATL-E at 3.0 V?
The HZM6.2ZMFATL-E specifies a maximum reverse current (IR) of 2 µA at VR = 3.0 V and Ta = 25°C. This low leakage supports ultra-low-power applications such as battery-operated sensor nodes and standby-mode voltage references where sub-microamp drain is essential for extended operational life.
Can HZM6.2ZMFATL-E replace standard 6.2 V Zener diodes in existing SOT-23 designs?
No - HZM6.2ZMFATL-E uses the MPAK (PLSP0003ZC-A) package with a unique 3-pin arrangement (NC-Anode-Cathode), differing from SOT-23's Anode-Cathode-NC or Cathode-Anode configurations. Direct replacement would require PCB layout revision, solder mask adjustment, and verification of thermal relief under the NC pad. It is not a drop-in substitute for SOT-23 Zeners.
What is the temperature coefficient of HZM6.2ZMFATL-E, and how does it affect reference stability?
The HZM6.2ZMFATL-E exhibits a temperature coefficient (γZ) of +0.04 mV/°C near its 6.2 V operating point, as confirmed in Figure 2 of the R07DS0358EJ0600 datasheet. This low, predictable drift enables stable reference performance across –40°C to +125°C ambient ranges, especially when paired with complementary components in compensated reference circuits.
