Product details
Overview
HZM6.2NB1TR-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and power-supply reference circuits, with a nominal zener voltage of 6.47–6.73 V at 5 mA, dynamic resistance of 50 Ω max, and power dissipation rating of 200 mW in the MPAK (SC-59A) surface-mount package.
For engineers reviewing the HZM6.2NB1TR-E datasheet, HZM6.2NB1TR-E pinout, HZM6.2NB1TR-E application, or HZM6.2NB1TR-E equivalent, this device serves as a stable, low-noise voltage reference in battery-powered instrumentation, sensor signal conditioning, and DC-DC feedback loops where tight tolerance and thermal stability are required.
Technical Context
The HZM6.2NB1TR-E operates as a two-terminal shunt regulator, maintaining a fixed reverse-biased breakdown voltage across its cathode-anode terminals under controlled test current (IZ = 5 mA). Its epitaxial planar construction ensures consistent breakdown characteristics and low leakage.
It exhibits a positive temperature coefficient of approximately +0.03 mV/°C near 6.2 V (per Fig.2), enabling predictable drift behavior in ambient temperature ranges from –55°C to +150°C, and is rated for junction temperatures up to 150°C with storage capability down to –55°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.47–6.73 V at IZ = 5 mA - defines precise regulation point for feedback or reference use |
| Dynamic Resistance (rd) | ≤50 Ω at IZ = 5 mA - ensures minimal output voltage variation under load transients |
| Maximum Power Dissipation (Pd) | 200 mW at Ta = 25°C - limits continuous operating current to ~32 mA at 6.2 V |
| Reverse Current (IR) | ≤2 μA at VR = 3.0 V - guarantees low leakage in standby or high-impedance bias networks |
| Junction Temperature (Tj) | 150°C maximum - supports operation in compact, thermally constrained PCB layouts |
| Package | MPAK (JEITA: PLSP0003ZC-A, SC-59A equivalent) - enables high-density SMT assembly with 0.65 mm lead pitch |
Pinout & Package
MPAK (SC-59A) surface-mount package: 3-terminal plastic molded case with gull-wing leads; dimensions per Page 6 (D = 2.7–3.1 mm, E = 1.35–1.65 mm, L = 0.65 mm); mass ≈ 0.011 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected terminal - must remain floating; no routing or soldering required |
| 2 | Anode | Forward-bias terminal; connected to lower-potential node in shunt regulation configuration |
| 3 | Cathode | Breakdown terminal; connected to regulated voltage node and current-limiting resistor |
Key Features
| Feature | Design Value |
|---|---|

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 (ON Semiconductor) | Same 6.2 V nominal, SOT-23 package, 400 mW Pd, but wider VZ tolerance (±5%) and higher rd (60 Ω) | Higher power handling but looser regulation; suited for non-critical biasing, not precision references | Select when board space allows SOT-23 and ±5% VZ is acceptable |
| MMSZ4688 (Vishay) | 6.2 V nominal, SOD-123 package, 500 mW Pd, VZ tolerance ±5%, rd = 60 Ω, Tj = 150°C | Larger footprint and higher leakage (IR ≤ 3 μA @ 4.96 V); better for higher-current shunt use | Choose for legacy SOD-123 designs requiring >200 mW dissipation |
Compared with BZX84-C6V2 and MMSZ4688, the HZM6.2NB1TR-E offers superior voltage tolerance (±2.2% vs. ±5%), lower dynamic resistance (50 Ω vs. 60 Ω), and optimized MPAK packaging for ultra-dense layouts-making it preferred for space-constrained, mid-precision analog references where thermal stability and repeatability matter.

FAQ
What is the exact zener voltage range for HZM6.2NB1TR-E at 5 mA test current?
The HZM6.2NB1TR-E has a specified zener voltage range of 6.47 V to 6.73 V when tested at IZ = 5 mA and Ta = 25°C. This corresponds to Grade B1 tolerance (±2.2% around nominal 6.2 V), confirmed in Table on Page 2 of R07DS0358EJ0600 Rev.6.00. The HZM6.2NB1TR-E achieves tighter regulation than standard B-grade variants in the same family.
Does HZM6.2NB1TR-E have a functional third pin, and how should Pin 1 be handled in layout?
No-Pin 1 of the HZM6.2NB1TR-E is explicitly designated "NC" (No Connect) in the Pin Arrangement diagram on Page 1. It is internally unconnected and must remain electrically floating; no trace, pad, or solder connection should be made to Pin 1. Layout guidelines require isolation from adjacent nets and avoidance of thermal reliefs or stitching vias on that pad.
What is the maximum reverse current specification for HZM6.2NB1TR-E, and at what voltage is it measured?
The HZM6.2NB1TR-E specifies a maximum reverse current (IR) of 2 μA, measured at a reverse voltage (VR) of 3.0 V (Page 2, Electrical Characteristics table). This low leakage supports high-impedance bias networks and extends battery life in always-on monitoring circuits using the HZM6.2NB1TR-E as a reference element.
Can HZM6.2NB1TR-E replace a standard 6.2 V Zener like 1N4735A in existing designs?
No direct drop-in replacement is assured: the HZM6.2NB1TR-E uses a 3-pin MPAK package with Pin 1 NC, whereas 1N4735A is a 2-pin DO-41 through-hole device. Electrical parameters differ-HZM6.2NB1TR-E has lower Pd (200 mW vs. 1 W) and tighter VZ tolerance, but requires PCB redesign for SMT and pinout compatibility. Use only after validating thermal and layout constraints for the HZM6.2NB1TR-E.
Is HZM6.2NB1TR-E suitable for automotive applications, and what quality grade does it carry?
The HZM6.2NB1TR-E is classified as "Standard" quality per Renesas' grading policy (Page 6, Notice #7), intended for office equipment, communications gear, and industrial robots-not automotive safety-critical or "High Quality" systems. Its 150°C Tj rating supports under-hood temperature ranges, but qualification data (AEC-Q101, PPAP) is not provided in the preliminary datasheet R07DS0358EJ0600, so HZM6.2NB1TR-E should not be deployed in automotive without additional validation.
