Product details

Overview

BCR3AM-14B#B00 from Renesas Electronics is a 700V, 3A non-continuous RMS triac in TO-92* package, designed for AC phase control in low-power motor drives and resistive/inductive load switching. It features 800V V_DRM at 125°C, 150°C max junction temperature, and 30mA gate trigger current across all quadrants.

For engineers reviewing the BCR3AM-14B#B00 datasheet, BCR3AM-14B#B00 pinout, BCR3AM-14B#B00 application, or BCR3AM-14B#B00 equivalent, key selection criteria include non-continuous conduction rating, dv/dt immunity (5 V/μs), thermal resistance (50°C/W), and RoHS/halogen-free compliance per PRSS0003DJ-A.

Technical Context

This planar passivated triac operates in all four quadrants with identical gate trigger characteristics (V_{FGT I}/V_{RG T I}/V_{RG T III} ≤ 1.5 V, I_{F GT I}/I_{R GT I}/I_{R GT III} ≤ 30 mA at 25°C). Its critical commutating dv/dt rating is 5 V/μs at 125°C, supporting reliable turn-off under inductive load conditions.

Thermal design is constrained by R_th(j-c) = 50°C/W and allowable case temperature limits - e.g., 120°C at 2.5 A RMS with natural convection and no heatsink. The device's 360° conduction capability supports full-wave AC control without external commutation circuitry.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DRM	800 V at T_j = 125°C - ensures off-state blocking in 230V AC mains with margin
I_T(RMS)	3 A non-continuous - suitable for intermittent motor start/stop, not continuous duty
I_TSM	30 A surge (60 Hz, 1 cycle) - withstands inrush currents during cold-start of small motors
(dv/dt)_c	5 V/μs at T_j = 125°C - defines minimum snubber requirement for inductive loads
V_TM	≤1.6 V at I_TM = 4.5 A - determines on-state power loss (≈7.2 W peak) and thermal budget
R_th(j-c)	50 °C/W - sets maximum allowable power dissipation at given case temperature
T_j max	+150 °C - enables operation in sealed enclosures with elevated ambient temperatures

Pinout & Package

BCR3AM-14B#B00 uses the TO-92* package (RENESAS code PRSS0003EA-A), a variant of TO-92 with modified lead form and dimensions (e.g., 11.5 mm min body length, 5.0 mm max diameter). Pin assignment follows standard triac configuration.

Pin/Terminal	Circuit Role	Design Meaning
1 (T2)	Anode 2 / Main Terminal 2	Primary current path terminal; used as reference point for case temperature measurement (1.5 mm from molded case)
2 (T1)	Anode 1 / Main Terminal 1	Second main current path; polarity defines quadrant conduction behavior during triggering
3 (Gate)	Control input	Accepts low-energy trigger pulses (≤0.5 A peak, ≤6 V) to initiate conduction in any quadrant

Key Features

Feature	Design Value
Quadrant III gate trigger compatibility	Identical 30 mA trigger current and 1.5 V trigger voltage as Quadrants I/II - enables simplified single-resistor gate drive
Planar passivation structure	Enhances long-term reliability and moisture resistance in humid environments without hermetic sealing
RoHS + halogen-free + Pb-free	Complies with PRSS0003DJ-A environmental specification - meets global regulatory requirements for consumer and industrial products
Non-continuous RMS rating	3 A rating applies only to intermittent operation (e.g., fan speed control, lamp dimming), not sustained load
Low holding current	Typical 10–20 mA across temperature range - ensures stable latching after trigger, even at high T_j

Equivalent & Alternatives

The following parts are listed as comparable options for similar triac applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCR3AM-14LB#BD0	Same electrical specs but TO-92 (PRSS0003DJ-A) package; active status vs. #B00 obsolete	Compatible pinout and thermal profile; differs only in lead form and packaging quantity (1000 pcs vs. 500 pcs)	Select for new designs requiring active supply chain and standard TO-92 footprint
BT134-600D	600V V_DRM, 4A RMS, TO-92 package; higher current but lower voltage rating	Suitable for 120V AC systems only; requires derating or snubbers for 230V use	Choose when operating exclusively on North American 120V AC mains and higher continuous current is needed

Compared with BCR3AM-14B#B00, the BCR3AM-14LB#BD0 offers identical performance in an actively supported package, while BT134-600D trades voltage margin for higher RMS current - making it viable only in lower-voltage, higher-duty-cycle applications.

FAQ

What is the maximum junction temperature rating for BCR3AM-14B#B00?

The BCR3AM-14B#B00 has a maximum junction temperature (T_j) of +150°C, validated across all electrical parameters including V_DRM (700 V), (dv/dt)_c (1 V/μs), and gate trigger characteristics. This allows operation in thermally constrained environments such as sealed appliance housings, provided case temperature remains within derated limits per the datasheet curves on Page 4.

Is BCR3AM-14B#B00 pin-compatible with other TO-92 triacs like BT136 or TIC226?

No - BCR3AM-14B#B00 uses TO-92* (PRSS0003EA-A) with pin order T2-T1-Gate (pin 1–2–3), whereas BT136 and TIC226 follow standard TO-92 pinout (T1-T2-Gate). Physical fit does not guarantee functional compatibility; gate trigger thresholds, dv/dt ratings, and thermal resistance differ significantly. Always verify pin mapping and quadrant behavior before substitution.

Does BCR3AM-14B#B00 support full-wave AC control without external components?

Yes - the BCR3AM-14B#B00 is a four-quadrant triac capable of triggering with gate signals in all quadrants (I, II, III, IV), enabling direct full-wave phase control using a single zero-crossing detector and resistor-limited gate drive. No external diodes or complementary SCRs are required, simplifying PCB layout and reducing BOM count for basic dimming or motor control circuits.

What is the surge current rating of BCR3AM-14B#B00 and how is it defined?

The BCR3AM-14B#B00 has a non-repetitive surge on-state current (I_TSM) of 30 A, specified for one full cycle (16.7 ms) of 60 Hz sine wave at peak value. This rating applies to short-duration inrush events such as motor startup or cold filament turn-on. It must not be exceeded repeatedly, and thermal recovery time between surges must comply with the I²t limit of 3.7 A²s to prevent junction damage.

Why is BCR3AM-14B#B00 marked as obsolete and what is the recommended replacement?

BCR3AM-14B#B00 is obsolete per Renesas' ordering information (Page 8), with #BD0 variants (e.g., BCR3AM-14B#BD0) designated as active. The recommended replacement is BCR3AM-14LB#BD0 - identical electrically and mechanically (TO-92, PRSS0003DJ-A), with same 3A/800V/150°C specs and active supply chain support. Migration requires no PCB change, only updated procurement and documentation.
