Product details
Overview
HZM6.2NB2TR-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 ≤50 Ω, reverse current ≤2 μA at 3.0 V, and power dissipation up to 200 mW in the MPAK (SC-59A) package - ideal for compact voltage reference and overvoltage protection in sensor signal conditioning.
For engineers reviewing the HZM6.2NB2TR-E datasheet, HZM6.2NB2TR-E pinout, HZM6.2NB2TR-E application, or HZM6.2NB2TR-E equivalent, key selection criteria include its B2-grade zener tolerance (±4.3% at 6.2 V), temperature coefficient of +0.03 mV/°C, MPAK surface-mount compatibility, and suitability for space-constrained industrial and automotive control modules requiring stable 6.2 V references.
Technical Context
The HZM6.2NB2TR-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 leakage across ambient temperatures from –55°C to +150°C.
Designed for DC biasing and voltage clamping, it exhibits a typical dynamic resistance of 50 Ω at 5 mA test current and a junction temperature limit of 150°C. The device is optimized for pulse-tested operation (Pw = 40 ms), supporting reliable performance in transient-suppression and reference-divider applications without thermal runaway under defined power limits.
Key Specifications

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 (Diodes Inc.) | Same 6.2 V nominal, SOT-23 package, ±5% tolerance (wider than HZM6.2NB2TR-E's ±4.3%), rd = 60 Ω | Higher dynamic resistance and looser tolerance reduce reference stability in precision analog circuits | Preferred where cost sensitivity outweighs 0.3% VZ accuracy and 10 Ω rd advantage |
| MMSZ5234B (ON Semiconductor) | 6.2 V nominal, SOD-123 package, ±5%, rd = 70 Ω, Pd = 350 mW - higher power but larger footprint | Larger package increases board area; higher Pd unnecessary for sub-200 mW reference use cases | Chosen when legacy SOD-123 layout exists or >200 mW derating margin is required |
Compared with BZX84-C6V2 and MMSZ5234B, the HZM6.2NB2TR-E offers superior voltage accuracy and lower dynamic resistance in the smallest MPAK footprint - making it optimal for new designs prioritizing precision, size, and thermal efficiency in 6.2 V reference nodes.

FAQ
What is the exact zener voltage range for HZM6.2NB2TR-E at 5 mA?
The HZM6.2NB2TR-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 B2-grade specification reflects ±4.3% tolerance around the nominal 6.2 V rating, confirmed in Renesas' R07DS0358EJ0600 datasheet, page 2. The HZM6.2NB2TR-E maintains this range across its qualified operating temperature span.
Is pin 1 of HZM6.2NB2TR-E electrically connected internally?
No - pin 1 of the HZM6.2NB2TR-E is designated NC (No Connect) and is not bonded to any internal die structure. As shown in the "Pin Arrangement" diagram on page 1 of the datasheet, only pins 2 (Anode) and 3 (Cathode) form the functional Zener junction. Leaving pin 1 unconnected is mandatory; soldering or routing to it may compromise reliability or violate JEDEC MPAK mechanical specifications.
What is the maximum reverse current specification for HZM6.2NB2TR-E, and at what voltage is it measured?
The HZM6.2NB2TR-E specifies a maximum reverse current (IR) of 2 μA, measured at a reverse voltage (VR) of 3.0 V and Ta = 25°C. This value appears in the "Electrical Characteristics" table on page 2 of the datasheet under the HZM6.2N row, Grade B2 column. It reflects ultra-low leakage critical for battery-powered reference and bias applications.
Can HZM6.2NB2TR-E be used in place of a standard 6.2 V Zener diode like 1N4735A?
No - the HZM6.2NB2TR-E is not a drop-in replacement for through-hole Zeners such as the 1N4735A. It uses the MPAK (SC-59A) surface-mount package with three terminals (including NC), whereas the 1N4735A is DO-41 packaged with two leads. Additionally, the HZM6.2NB2TR-E has tighter tolerance (±4.3% vs. ±5%) and lower dynamic resistance (50 Ω vs. ~8 Ω at 41 mA), but requires PCB redesign for footprint and pinout compatibility.
What is the temperature coefficient of HZM6.2NB2TR-E, and how does it affect long-term stability?
The HZM6.2NB2TR-E exhibits a temperature coefficient (γZ) of +0.03 mV/°C, as plotted in Figure 2 on page 5 of the datasheet. This near-zero drift characteristic means its zener voltage changes by only ~3 mV over a 100°C ambient range - significantly improving long-term stability in unregulated environments compared to higher-drift Zeners (e.g., >10 mV/°C). This directly enhances accuracy in HZM6.2NB2TR-E-based reference dividers.
