Product details
Overview
HZM6.2NB2JTR-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 50 Ω, power dissipation up to 200 mW, and operates within –55°C to +150°C storage temperature range. It is commonly used in voltage reference generation for sensor signal conditioning and power supply feedback loops.
For engineers reviewing the HZM6.2NB2JTR-E datasheet, HZM6.2NB2JTR-E pinout, HZM6.2NB2JTR-E application, or HZM6.2NB2JTR-E equivalent, key selection criteria include zener voltage tolerance (±2.2% at B2 grade), low dynamic impedance for stable regulation, MPAK package compatibility with high-density SMT assembly, and thermal performance under ambient temperatures up to 75°C.
Technical Context
This device functions as a two-terminal shunt voltage regulator, operating in reverse breakdown mode with controlled zener characteristics. Its epitaxial planar structure ensures tight voltage distribution and low leakage, while the MPAK package enables efficient thermal transfer via its exposed cathode pad.
The HZM6.2NB2JTR-E exhibits a positive temperature coefficient of approximately +0.04 mV/°C near 6.2 V, minimizing drift in mid-range zener applications. It is rated for 2 µA maximum reverse current at VR = 3.0 V and supports pulse testing per 40 ms duration per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2LT1G | Zener voltage 6.04–6.36 V (±5%), 350 mW Pd, SOT-23 package, rd = 60 Ω | Higher power rating but looser tolerance and larger footprint; less suitable for space-constrained precision references | Prefer when higher surge energy handling is required and ±5% VZ is acceptable |
| MMSZ4687ET1G | Zener voltage 6.02–6.46 V (±5%), 500 mW Pd, SOD-123 package, rd = 70 Ω | Higher power and cost-effective, but wider VZ spread and inferior thermal performance in compact layouts | Choose for general-purpose regulation where board area is not constrained and cost is prioritized |
Compared with BZX84-C6V2LT1G and MMSZ4687ET1G, the HZM6.2NB2JTR-E offers tighter voltage tolerance (±2.2% vs. ±5%), lower dynamic resistance (50 Ω vs. ≥60 Ω), and smaller MPAK footprint - making it optimal for precision, space-sensitive, and thermally constrained designs.

FAQ
What is the zener voltage tolerance for HZM6.2NB2JTR-E?
The HZM6.2NB2JTR-E has a zener voltage range of 6.26 V to 6.53 V at 5 mA test current, corresponding to ±2.2% tolerance for Grade B2. This tighter specification than standard ±5% zeners supports higher-accuracy voltage references in precision analog circuits without trimming components.
Does HZM6.2NB2JTR-E require a heatsink in typical operation?
No, the HZM6.2NB2JTR-E does not require an external heatsink under standard conditions. Its 200 mW power rating is achievable on a standard FR-4 PCB with 1.6 mm copper thickness, and the MPAK package's exposed cathode pad provides sufficient thermal conduction for ambient temperatures up to 75°C at full rated power.
Can pin 1 (NC) of HZM6.2NB2JTR-E be connected to ground?
No - pin 1 is electrically unconnected (NC) and must remain floating or be left unpopulated. Connecting it to ground or any other node may cause unpredictable behavior or violate internal isolation design. Layout guidelines explicitly prohibit routing or soldering to pin 1.
How does the temperature coefficient of HZM6.2NB2JTR-E affect long-term stability?
The HZM6.2NB2JTR-E exhibits a temperature coefficient of approximately +0.04 mV/°C near its 6.2 V operating point. Over a –25°C to +85°C range, this contributes ~4.4 mV total drift - well within ±0.1% of nominal VZ, supporting stable performance in unregulated environments without active compensation.
Is HZM6.2NB2JTR-E RoHS compliant and halogen-free?
Yes, HZM6.2NB2JTR-E complies with EU RoHS Directive 2011/65/EU and is halogen-free per Renesas' material declarations. The MPAK package uses lead-free matte tin plating and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), allowing unlimited floor life before reflow.
