Product details
Overview
HZM6.2NB3TL-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 6.26–6.53 V at 5 mA, with dynamic resistance of 3.0 Ω, reverse current ≤2 μA at 4.0 V, and power dissipation up to 200 mW in the MPAK (SC-59A) package - commonly used in power supply feedback loops and sensor biasing.
For engineers reviewing the HZM6.2NB3TL-E datasheet, HZM6.2NB3TL-E pinout, HZM6.2NB3TL-E application, or HZM6.2NB3TL-E equivalent, key selection criteria include its B3-grade voltage tolerance (±2.2% typical), low temperature coefficient (~+0.03 mV/°C near 6.2 V), surface-mount MPAK footprint compatibility, and suitability for space-constrained industrial and consumer voltage reference designs.
Technical Context
The HZM6.2NB3TL-E operates as a two-terminal shunt regulator, maintaining stable output voltage by conducting reverse current above its specified zener breakdown threshold. Its epitaxial planar construction ensures tight voltage distribution and low noise performance critical for analog signal conditioning.
Designed for DC stabilization rather than transient suppression, it exhibits a junction temperature limit of 150°C and storage range from –55°C to +150°C. The device is characterized under pulsed test conditions (Pw = 40 ms), ensuring reliable steady-state operation when derated per Fig.3 power vs. ambient temperature curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.26–6.53 V at IZ = 5 mA - defines precise regulation point for feedback networks |
| Dynamic Resistance (rd) | 3.0 Ω max at IZ = 5 mA - determines load regulation sensitivity and ripple rejection |
| Reverse Current (IR) | ≤2 μA at VR = 4.0 V - ensures minimal leakage in standby or high-impedance bias paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2 (Nexperia) | Same nominal VZ (6.2 V), but ±5% tolerance (B grade); SOT-23 package; rd = 10 Ω max | Higher dynamic impedance limits use in precision feedback; wider tolerance requires system calibration | Select when cost sensitivity outweighs regulation accuracy and board space allows SOT-23 footprint |
| MMSZ4687 (ON Semiconductor) | VZ = 6.2 V ±5%, SOD-123 package; Pd = 500 mW; rd = 7 Ω max; Tj = 150°C | Higher power rating suits higher-current biasing, but larger package and looser tolerance reduce density and precision | Prefer for high-reliability industrial bias where thermal margin >200 mW is required and layout accommodates SOD-123 |
Compared with BZX84-C6V2 and MMSZ4687, the HZM6.2NB3TL-E offers tighter B3-grade voltage matching, lower dynamic resistance, and a smaller MPAK footprint - making it optimal for compact, high-accuracy voltage reference designs where leakage and thermal constraints are critical.

FAQ
What is the exact zener voltage range for HZM6.2NB3TL-E at 5 mA?
The HZM6.2NB3TL-E has a guaranteed zener voltage range of 6.26 V to 6.53 V when tested at IZ = 5 mA and Ta = 25°C. This B3-grade specification reflects ±2.2% tolerance around the nominal 6.2 V rating, confirmed in Table on Page 2 of R07DS0358EJ0600 Rev.6.00. The HZM6.2NB3TL-E is not rated for tighter tolerances outside this range.
Does HZM6.2NB3TL-E have a pin 1 functional connection?
No - pin 1 of the HZM6.2NB3TL-E is designated "NC" (No Connect) per the Pin Arrangement diagram on Page 1 of the datasheet. It is electrically isolated and must remain unconnected on the PCB; routing or soldering to pin 1 may introduce parasitic capacitance or mechanical stress that degrades HZM6.2NB3TL-E regulation stability.
What is the maximum allowable reverse current for HZM6.2NB3TL-E before breakdown?
The HZM6.2NB3TL-E specifies a maximum reverse current IR of 2 μA at VR = 4.0 V (Page 2, Electrical Characteristics table). This is not a "breakdown threshold" but a leakage limit below the zener knee - actual breakdown begins near 6.2 V. Exceeding 4.0 V while staying below 6.2 V will increase IR, but the HZM6.2NB3TL-E remains in safe, non-conductive reverse bias until reaching its zener region.
Can HZM6.2NB3TL-E be used in place of a standard 6.2 V Zener like 1N4735A?
No - the HZM6.2NB3TL-E is not a drop-in replacement for through-hole devices like the 1N4735A. It uses a 3-pin MPAK (SC-59A) package with pin 1 NC, whereas the 1N4735A is a 2-pin DO-41 device. Additionally, the HZM6.2NB3TL-E has tighter B3-grade tolerance (±2.2%) and lower rd (3.0 Ω), but requires re-layout and validation for SMT assembly and thermal management per its 200 mW rating.
Is HZM6.2NB3TL-E compliant with RoHS and lead-free soldering standards?
Yes - the HZM6.2NB3TL-E meets EU RoHS Directive requirements, as confirmed in Renesas' environmental compliance documentation referenced in Section 10 of the datasheet. It supports lead-free reflow profiles (JEDEC J-STD-020), with peak temperature tolerance up to 260°C for 10 seconds, consistent with standard Pb-free assembly processes for the MPAK package.
