Product details
Overview
BD13716STU from Fairchild Semiconductor is an NPN epitaxial silicon transistor in TO-126 package, rated for 60 V VCEO, 1.5 A DC collector current, and 12.5 W collector dissipation at TC = 25°C. It serves as a medium-power linear amplifier or switching device in audio output stages and power supply regulators.
For engineers reviewing the BD13716STU datasheet, pinout, applications, or equivalent options, key selection criteria include VCEO = 60 V, hFE = 63–160 (at IC = 150 mA), VCE(sat) ≤ 0.5 V (IC = 500 mA, IB = 50 mA), thermal derating above 25°C, and complementary pairing with BD138.
Technical Context
This transistor operates in active, saturation, and cutoff regions with specified safe operating area (SOA) limits up to 100 V and 1 A under pulsed conditions. Its hFE classification "16" corresponds to 100–250 gain range at IC = 150 mA, VCE = 2 V - distinct from BD135 (class 6) and BD139 (class 10).
VCEO(sus) = 60 V confirms sustaining capability under open-base switching conditions. Base-emitter on voltage is 1.0 V at IC = 0.5 A, supporting predictable drive requirements in Class AB audio stages and relay drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - maximum continuous collector-emitter voltage before breakdown; defines safe DC rail limit in switching applications |
| IC (DC) | 1.5 A - max steady-state collector current; sets upper bound for continuous load handling in linear regulators |
| PC (TC=25°C) | 12.5 W - thermal power limit at case temperature 25°C; requires heatsink for sustained operation above ~1.25 W ambient |
| hFE (IC=150 mA) | 100–250 - current gain range enabling stable biasing in emitter-follower or common-emitter amplifiers |
| VCE(sat) | ≤0.5 V @ IC=500 mA, IB=50 mA - low saturation voltage minimizes conduction loss in switching mode |
| TJ | 150°C - maximum junction temperature; determines thermal design margin when mounted on heatsink |
Pinout & Package
BD13716STU uses the TO-126 package: molded plastic case with three leads, tab-connected to collector, intended for through-hole mounting and heatsink attachment via metal tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Connected to ground or low-side return path; polarity defines NPN operation |
| 2 (Collector) | Current source terminal | Tab-connected; must be electrically isolated from heatsink unless circuit design permits common-collector reference |
| 3 (Base) | Control input | Receives forward-biased current to enable conduction; requires series resistor to limit IB ≤ 0.5 A |
Key Features
| Feature | Design Value |
|---|---|
| Complementary pairing | Designed as NPN match to PNP BD138; enables push-pull output stages without gain mismatch |
| Medium-power SOA | Rated for 60 V × 1 A pulsed operation per Figure 4 - supports transient overload in audio and motor control |
| hFE classification "16" | Guaranteed 100–250 gain at IC = 150 mA - simplifies bias network design vs. unclassified transistors |
| TO-126 mechanical standardization | Industry-standard footprint and tab geometry - ensures compatibility with legacy PCB layouts and heatsink clips |
Applications
| Audio Power Amplifier Output Stage | Linear Voltage Regulator Pass Element |
|---|---|
Use Scenario: Driving 4–8 Ω speakers in Class AB amplifier outputs with ±15 V rails. IC Role / Device Role / Timing Role: NPN output transistor delivering peak current up to 1.2 A into reactive loads. Use Value: VCEO = 60 V and SOA support safe operation during clipping transients; hFE consistency reduces crossover distortion. | Use Scenario: Series pass element in adjustable 3–24 V, 1 A linear regulators (e.g., LM317-based designs). IC Role / Device Role / Timing Role: High-current pass transistor dissipating up to 10 W under worst-case dropout conditions. Use Value: 12.5 W PC rating at TC = 25°C enables compact heatsinking; VCE(sat) ≤ 0.5 V lowers minimum dropout voltage. |
| DC Motor Driver (Low-Side Switch) | Relay Driver Interface |
Use Scenario: Controlling 12 V, 800 mA brushed DC motors in industrial actuators. IC Role / Device Role / Timing Role: Low-side switch turning motor current on/off via microcontroller GPIO. Use Value: IC = 1.5 A DC rating exceeds motor stall current; fast turn-on/turn-off supported by low VBE(on) = 1.0 V. | Use Scenario: Driving 12 V, 400 mA coil relays in PLC I/O modules. IC Role / Device Role / Timing Role: General-purpose switching transistor interfacing logic-level signals to inductive loads. Use Value: VCEO(sus) = 60 V withstands flyback spikes up to 50 V; built-in ESD robustness per Fairchild process enhances field reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BD137G | Same electrical specs, Pb-free TO-126 package per RoHS; no internal differences in gain or voltage ratings | Identical use cases; preferred where lead-free compliance is mandatory | Select BD137G for new designs requiring RoHS-6 compliance; BD13716STU remains valid for legacy repair or non-RoHS environments |
| MJE13003 | Higher VCEO = 700 V, lower hFE = 5–30, TO-220 package - not drop-in compatible | Suitable for high-voltage flyback or SMPS primary switches, not linear/audio applications | Choose MJE13003 only for high-voltage switching; avoid in BD13716STU's linear or medium-voltage roles due to gain and SOA mismatch |
Compared with BD13716STU, BD137G offers identical performance with RoHS compliance, while MJE13003 trades gain and SOA for high-voltage ruggedness - making it unsuitable as a functional replacement but viable only in high-VCE switching contexts.

FAQ
What is the hFE range for BD13716STU at IC = 150 mA?
The BD13716STU has an hFE classification of "16", meaning its DC current gain is guaranteed between 100 and 250 when measured at VCE = 2 V and IC = 150 mA. This range is tighter than BD135 (40–100) and BD139 (63–160), supporting more predictable biasing in precision linear circuits. The BD13716STU's gain stability aids consistent performance across production lots.
Is BD13716STU pin-compatible with BD138?
No, BD13716STU is not pin-compatible with BD138 - it is its complementary PNP counterpart, not a replacement. BD13716STU uses TO-126 with pinout E-C-B (1-2-3), while BD138 shares the same package and pinout but is PNP. They are intended for paired use in push-pull stages, not interchange. Substituting BD13716STU for BD138 would reverse polarity and cause circuit failure.
What is the maximum allowable collector dissipation for BD13716STU at 75°C case temperature?
Per the power derating curve in the BD13716STU datasheet, collector dissipation must be linearly reduced from 12.5 W at TC = 25°C. At TC = 75°C, the allowable PC is 12.5 W − (50°C × 0.1 W/°C) = 7.5 W. This reflects the 0.1 W/°C derating slope shown in Figure 5. Exceeding this risks junction overheating beyond the 150°C limit.
Does BD13716STU support pulse operation above its DC current rating?
Yes, BD13716STU supports pulsed collector current up to 3.0 A (ICP) with duty cycle and pulse width within SOA limits. Figure 4 confirms safe operation at 1 A for 1 ms pulses. However, pulse operation must respect VCE–IC boundaries - e.g., 3 A pulses require VCE < 20 V. Always verify against the SOA plot, not just ICP, to prevent second breakdown.
Can BD13716STU replace BD139 in a circuit?
No - BD13716STU is not a direct replacement for BD139. While both are NPN TO-126 transistors, BD139 has VCEO = 80 V and hFE class "10" (63–160), whereas BD13716STU is rated for 60 V and hFE class "16" (100–250). Using BD13716STU in a BD139-design may cause overvoltage failure if rail exceeds 60 V, and gain mismatch could affect bias stability.
