Product details
Overview
HZM6.2NB1JTL-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, power dissipation of 200 mW, and MPAK surface-mount package. It operates within –55°C to +150°C storage range and supports stable regulation in DC bias networks, overvoltage protection clamps, and feedback references for LDOs and switching regulators.
For engineers reviewing the HZM6.2NB1JTL-E datasheet, HZM6.2NB1JTL-E pinout, HZM6.2NB1JTL-E application, or HZM6.2NB1JTL-E equivalent, key selection criteria include its B1-grade zener voltage tolerance (±2.2% at 6.6 V), low dynamic impedance, temperature coefficient near zero (–0.01 to +0.03 mV/°C), and compatibility with high-density SMT assembly on standard FR-4 PCBs.
Technical Context
The HZM6.2NB1JTL-E uses a silicon epitaxial planar junction structure optimized for tight zener voltage control and low noise in stabilization applications. Its electrical behavior is defined at 5 mA test current, with reverse current limited to ≤2 μA at VR = 3.0 V and junction temperature capped at 150°C.
It belongs to the HZM-N series offering graded voltage options (B1/B2/B3) across 1.9–38 V, with this variant specifically calibrated for mid-range stabilization where ±2.2% initial accuracy and <50 Ω dynamic resistance are critical for feedback loop stability and load regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.47–6.73 V at IZ = 5 mA - defines precise DC reference point for regulator feedback or clamp threshold |
| Dynamic Resistance (rd) | ≤50 Ω at IZ = 5 mA - ensures minimal output voltage shift under varying load current |
| Power Dissipation (Pd) | 200 mW - supports continuous operation in compact PCB layouts without forced cooling |
| Reverse Current (IR) | ≤2 μA at VR = 3.0 V - guarantees low leakage in high-impedance bias networks |
| Junction Temperature (Tj) | 150°C maximum - enables reliable operation in industrial ambient environments up to +85°C |
| Temperature Coefficient (γZ) | –0.01 to +0.03 mV/°C - provides near-zero drift across operating temperature range |
Pinout & Package
Package: MPAK (JEITA code PLSP0003ZC-A), 3-pin surface-mount plastic package with 1.0 mm × 1.3 mm footprint, 0.55 mm terminal pitch, and 0.1–0.26 mm lead thickness - optimized for automated pick-and-place and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Electrically isolated terminal; must remain unconnected to avoid parasitic coupling or thermal stress |
| 2 | Anode | Forward-biased terminal during conduction; connects to lower-potential node in reverse-bias stabilization configuration |
| 3 | Cathode | Zener breakdown terminal; connects to regulated output node or reference point in shunt regulator topology |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4687T1G | Zener voltage 6.2 V (±5%), Pd = 350 mW, SOD-123 package, rd = 60 Ω | Higher power rating but wider voltage tolerance and larger footprint (2.7 × 1.6 mm vs. 1.3 × 1.0 mm) | Preferred when higher surge energy handling is required and board space permits larger package |
| BZX84-C6V2 | Zener voltage 6.2 V (±5%), Pd = 300 mW, SOT-23 package, rd = 60 Ω, no NC pin | Three-terminal SOT-23 lacks NC pin; slightly higher dynamic resistance and looser grading | Suitable for cost-sensitive designs where B1-grade accuracy and MPAK density are not mandatory |
Compared with MMSZ4687T1G and BZX84-C6V2, the HZM6.2NB1JTL-E delivers tighter voltage tolerance (±2.2% vs. ±5%), smaller MPAK footprint, and lower dynamic resistance - making it optimal for space-constrained, high-accuracy analog reference and clamp functions where board real estate and regulation stability are prioritized.

FAQ
What is the exact zener voltage range specified for HZM6.2NB1JTL-E?
The HZM6.2NB1JTL-E has a guaranteed zener voltage range of 6.47 V to 6.73 V when tested at 5 mA forward current, corresponding to the B1 grade within the HZM-N series. This 2.2% tolerance band is tighter than standard B-grade parts and is confirmed in the Renesas preliminary datasheet R07DS0358EJ0600, page 2. The HZM6.2NB1JTL-E achieves this accuracy through laser-trimmed epitaxial junction processing.
Does HZM6.2NB1JTL-E have a no-connect (NC) pin, and how should it be handled on the PCB?
Yes, HZM6.2NB1JTL-E features Pin 1 as a no-connect (NC) terminal, as shown in the top-view pin arrangement diagram on page 1 of the datasheet. This pin must remain electrically unconnected - neither tied to ground nor routed - to prevent unintended coupling, thermal stress, or reliability degradation. The NC pin is part of the MPAK mechanical structure and serves no electrical function in the HZM6.2NB1JTL-E.
What is the maximum power dissipation and derating behavior of HZM6.2NB1JTL-E?
The HZM6.2NB1JTL-E has a maximum power dissipation of 200 mW at 25°C ambient, with linear derating above 25°C as shown in Figure 3 of the datasheet. Derating begins immediately beyond 25°C at approximately 1.6 mW/°C, reaching ~120 mW at 75°C ambient. This behavior is validated for standard FR-4 PCB mounting with 1.6 mm thickness and 1 oz copper, and must be accounted for in thermal design of the HZM6.2NB1JTL-E.
How does the temperature coefficient of HZM6.2NB1JTL-E compare to other 6.2 V Zener diodes?
The HZM6.2NB1JTL-E exhibits a temperature coefficient (γZ) between –0.01 mV/°C and +0.03 mV/°C, placing it near the zero-tempco point for silicon Zeners - significantly better than typical 6.2 V parts like BZX84-C6V2 (±3.5 mV/°C). This low drift is confirmed in Figure 2 of the datasheet and directly contributes to stable reference performance across –40°C to +85°C ambient in the HZM6.2NB1JTL-E.
Is HZM6.2NB1JTL-E RoHS-compliant and halogen-free?
Yes, HZM6.2NB1JTL-E complies with EU RoHS Directive 2011/65/EU and is halogen-free per JESD209-4 standards, as stated in Renesas' environmental compliance documentation referenced in the datasheet colophon. The device uses lead-free matte tin plating and green molding compound, and full material declarations are available upon request for the HZM6.2NB1JTL-E.
