Product details

Overview

E-L6210 from STMicroelectronics is a monolithic dual Schottky diode bridge IC containing eight discrete Schottky diodes configured as two independent full-wave bridges. It delivers 4 A peak current per bridge, 50 V peak reverse voltage per diode, and 1.2 V max forward voltage at 1 A, enabling high-efficiency bipolar stepper motor drive circuits in industrial motion control systems.

For engineers reviewing the E-L6210 datasheet, E-L6210 pinout, E-L6210 application, or E-L6210 equivalent, key selection considerations include its dual-bridge topology, thermal impedance (65 °C/W junction-to-ambient), low VF drift with temperature, GND-pin thermal anchoring requirement, and PDIP-16 (12+2+2) package layout for PCB copper heatsinking.

Technical Context

The E-L6210 integrates two electrically isolated Schottky full-wave rectifier bridges on a single die, each comprising four diodes arranged in standard bridge configuration. Each bridge supports up to 2 A repetitive forward current and exhibits fast recovery behavior due to Schottky barrier construction, eliminating minority-carrier storage delay.

Thermal management relies on soldering pins 1, 8, 9, and 16 (all GND) to large PCB copper areas or external heatsinks; R_TH(j-case) is 14 °C/W, and maximum ambient operating temperature is 70 °C without forced cooling. Parasitic inter-diode leakage (~10 mA at IF > 1 A) is documented under adjacent diode conduction conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Bridge count	Two independent full-wave Schottky bridges (8 diodes total)
Peak reverse voltage (per diode)	50 V - sets maximum allowable back-EMF or supply rail swing in stepper coil flyback paths
Forward voltage (IF = 1 A)	1.0–1.2 V - directly determines conduction loss and thermal load per bridge leg
Repetitive forward current (per bridge)	2 A - defines continuous coil current capability before thermal derating
Junction-to-ambient R_TH	65 °C/W - requires ≥2 cm² of 2-oz copper connected to GND pins for safe 2 A operation at 70 °C ambient
Operating ambient range	0 to +70 °C - specifies validated performance envelope without active cooling or derating
Package	PDIP-16 (12 + 2 + 2 lead count) - provides mechanical stability and thermal path via four GND pins

Pinout & Package

Package: 16-pin plastic dual in-line package (PDIP) with 2.54 mm pitch, 19.18 mm length, 7.87 mm width, and 3.30 mm height. Four dedicated GND pins (1, 8, 9, 16) serve as primary thermal and electrical reference points.

Pin/Terminal	Circuit Role	Design Meaning
1, 8, 9, 16	GND	Common cathode reference and thermal anchor points; must be soldered to ≥2 cm² copper pour for rated current
2, 3, 4, 5	Bridge 1 AC inputs / outputs	Form first full-wave bridge: pins 2/3 = AC input pair; pins 4/5 = DC output (+/–)
11, 12, 13, 14	Bridge 2 AC inputs / outputs	Form second full-wave bridge: pins 11/12 = AC input pair; pins 13/14 = DC output (+/–)
6, 7, 10, 15	No connect (NC)	Internally unconnected; left floating or tied to GND only if required for mechanical stability

Key Features

Feature	Design Value
Dual independent Schottky bridges	Enables simultaneous bidirectional coil energization in 4-wire bipolar stepper motors without external diode arrays
Low VF (0.8 V typ. @ 500 mA)	Reduces power dissipation by >35% vs. standard silicon rectifiers at same current, lowering heatsink requirements
Fast recovery (Schottky)	Eliminates reverse recovery charge (Q_rr ≈ 0), preventing switching spikes during PWM-controlled coil commutation
GND-pin thermal anchoring	Four dedicated GND pins allow direct thermal coupling to PCB copper, achieving 14 °C/W junction-to-case impedance
Pb-free ECOPACK® packaging	Complies with RoHS and JEDEC JESD97; marked with second-level interconnect category on package and inner box label

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual Schottky bridge applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STK12A	Single Schottky bridge (4 diodes), 3 A rating, TO-220 package	Requires two devices for dual-bridge function; higher thermal mass but no GND-pin heatsinking flexibility	Select when discrete mounting and higher surge tolerance outweigh PCB space and thermal design constraints
MBR20100CT	Single dual-common-cathode Schottky (2×10 A), TO-220AC package	Not pin-compatible; lacks isolation between bridges; VF = 0.95 V @ 10 A but no integrated dual-bridge topology	Select only for high-current single-bridge use cases where board space permits external isolation components

Compared with STK12A and MBR20100CT, the E-L6210 uniquely integrates two thermally anchored, electrically isolated Schottky bridges in one PDIP-16 package-enabling compact, low-VF, low-Q_rr stepper drive designs without discrete assembly or thermal interface compromises.

FAQ

What is the maximum continuous current per bridge of the E-L6210?

The E-L6210 supports 2 A repetitive forward current per bridge at T_AMB ≤ 70 °C with proper PCB copper heatsinking on pins 1, 8, 9, and 16. At 2 A, junction temperature rise is ~130 °C above ambient (65 °C/W × 2 A), so thermal design must ensure T_J stays below 150 °C. Derating is required above 70 °C ambient.

Can the E-L6210 be used in automotive applications?

No-the E-L6210 is specified only for 0 to +70 °C ambient operation and is not qualified to AEC-Q100. ST explicitly states non-automotive-grade products may be used in automotive systems only at the user's own risk. Its thermal and reliability profile is optimized for industrial and office equipment, not under-hood environments.

Why are pins 6, 7, 10, and 15 labeled NC in the E-L6210?

These pins are internally unconnected and serve no electrical function. They exist for mechanical symmetry and package compatibility within the PDIP-16 footprint. ST documentation confirms they may be left floating; tying them to GND is permissible only for mechanical reinforcement-not for thermal or electrical benefit.

How does the E-L6210 handle parasitic inter-diode current?

At forward currents exceeding 1 A, adjacent diodes exhibit ~10 mA parasitic leakage due to substrate coupling. This is documented in Section 2.3 of the datasheet and must be accounted for in precision current-sense feedback loops-especially in microstepping applications where sub-10 mA errors affect torque linearity.
