Product details

Overview

ST13007 from STMicroelectronics is a high-voltage fast-switching NPN power transistor rated for 700 V V_CES, 8 A continuous collector current, and 80 W total dissipation at T_C = 25 °C; it features low dynamic parameter spread, cellular emitter structure, and planar edge termination for enhanced RBSOA and switching speed; used in electronic ballasts and switch-mode power supplies.

For engineers reviewing the ST13007 datasheet, ST13007 pinout, ST13007 application, or ST13007 equivalent, key selection criteria include V_CEO = 400 V, t_s/t_f ≤ 2.5 µs/110 ns (inductive load), h_FE classification (A/B groups), R_thJC = 1.56 °C/W, and TO-220 package thermal performance.

Technical Context

This device employs high-voltage multi-epitaxial planar technology with a cellular emitter layout and planar edge termination to simultaneously sustain wide reverse-biased safe operating area (RBSOA) and achieve very high switching speeds. Its design targets hard-switched inductive loads with clamped V_CE = 250 V and I_C = 5 A, where storage time (t_s) and fall time (t_f) are specified at 1.5–2 µs and 40–70 ns respectively under those conditions.

The transistor supports two DC current gain classifications (Group A: h_FE = 16–30; Group B: h_FE = 26–40 at I_C = 2 A, V_CE = 5 V), and its absolute maximum ratings include V_CES = 700 V, I_C = 8 A, and T_J_max = 150 °C - enabling operation in high-voltage flyback and resonant converter topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	700 V - enables use in 400 V AC-input SMPS with margin for voltage spikes
I_C (continuous)	8 A - supports output power up to ~300 W in single-transistor forward converters
R_thJC	1.56 °C/W - allows 50 W dissipation at ΔT = 78 °C case-to-junction rise
t_s (inductive)	1.5–2 µs - limits switching loss during turn-off in clamp-based topologies
t_f (inductive)	40–110 ns - reduces overlap loss in hard-switched applications at 50–100 kHz
h_FE range	16–40 - ensures predictable base drive requirements across production lots
V_CE(sat)	1–3 V @ I_C = 2–8 A - defines conduction loss contribution in primary-side switching

Pinout & Package

ST13007 is housed in a TO-220 package with insulated tab (Type A/E mechanical variants), featuring three terminals: emitter (pin 1), base (pin 2), collector (pin 3), and electrically connected metal tab serving as collector terminal.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Emitter)	Current exit path from transistor	Low-inductance connection point for return path in high-di/dt circuits
Pin 2 (Base)	Control input for minority carrier injection	Requires robust drive capability (I_B ≤ 4 A peak) to ensure full saturation
Pin 3 (Collector)	Main high-voltage current path	Internally bonded to metal tab - must be electrically isolated from heatsink unless referenced to same potential
Metal tab	Collector terminal (electrically tied)	Primary thermal interface - requires insulating washer if heatsink is grounded

Key Features

Feature	Design Value
Cellular emitter structure	Enables uniform current distribution and reduced local hot-spot risk during overload
Planar edge termination	Improves voltage blocking stability and prevents premature edge breakdown at 700 V
Low dynamic parameter spread	Ensures consistent t_s/t_f and V_CE(sat) across production batches for reliable timing control
High V_CEO rating	400 V sustaining voltage supports operation in 230 V AC line applications without snubber oversizing

Applications

Electronic Ballast

Switch-Mode Power Supply

Use Scenario: High-frequency (20–60 kHz) resonant lamp ignition and regulation in fluorescent lighting systems.

IC Role / Device Role / Timing Role: Primary-side switching transistor in half-bridge or Royer oscillator topology.

Use Value: Fast t_f ≤ 110 ns and low t_s minimize dead-time losses and enable stable zero-voltage switching (ZVS) initiation.

Use Scenario: Primary-side switch in offline flyback or forward converters for industrial power supplies.

IC Role / Device Role / Timing Role: Hard-switched NPN power switch handling 400 V DC bus with 5–8 A peak current.

Use Value: V_CES = 700 V provides 75% overvoltage margin against 400 V rectified mains transients.

AC-DC Adapter

UPS Inverter Stage

Use Scenario: Compact 65–120 W AC-DC adapters requiring high efficiency and low EMI.

IC Role / Device Role / Timing Role: Main switching element in quasi-resonant flyback with active clamp.

Use Value: Low V_CE(sat) (1–3 V) reduces conduction loss while maintaining thermal headroom at 80 W dissipation.

Use Scenario: DC-AC inversion stage in line-interactive UPS with battery backup.

IC Role / Device Role / Timing Role: High-voltage switch in push-pull or half-bridge configuration driving transformer primary.

Use Value: Wide RBSOA and 150 °C T_Jmax support sustained 100% duty-cycle operation during brownout conditions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage NPN power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BU508A	V_CES = 1000 V, I_C = 12 A, slower t_f (~200 ns), no h_FE grouping	Better surge tolerance but higher switching loss in 50–100 kHz designs	Preferred where input voltage exceeds 450 V DC or transient immunity is critical
2SD1403	V_CES = 500 V, I_C = 10 A, t_f ≈ 150 ns, h_FE = 20–60 (unclassified)	Limited voltage margin for 230 V AC-derived rails; wider h_FE variation affects base drive design	Suitable only in lower-voltage (<350 V) SMPS with relaxed SOA requirements

Compared with BU508A and 2SD1403, ST13007 delivers tighter dynamic parameter control, defined h_FE groups for predictable drive, and optimized t_s/t_f balance for 20–100 kHz resonant and hard-switched topologies - making it preferred for ballast and mid-power SMPS where consistency and thermal reliability are prioritized.

FAQ

Is ST13007 RoHS-compliant and halogen-free?

Yes, ST13007 is manufactured in ECOPACK®-compliant versions meeting RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21. The device carries the "E" suffix (e.g., ST13007B) for ECOPACK® grade, with full compliance documentation available on ST's official website.

What is the recommended heatsink mounting method for ST13007 in TO-220?

Mount ST13007 using an electrically isolating thermal pad or mica washer between the metal tab and heatsink, with thermal grease applied to both sides. Torque the mounting screw to 0.5–0.6 N·m to ensure R_thJC ≤ 1.56 °C/W without cracking the package or compromising insulation integrity.

Can ST13007 replace BU2508DF in a 100 W SMPS design?

No - BU2508DF is a Darlington transistor with integrated driver and much higher h_FE (>1000), whereas ST13007 is a standard NPN requiring external base drive. Direct replacement would cause insufficient gain and thermal runaway; redesign of base drive circuitry and SOA verification is mandatory.

Does ST13007 support avalanche energy rating (E_AS) testing?

No - ST13007 datasheet does not specify single-pulse avalanche energy (E_AS) or repetitive avalanche ratings. It is not characterized for unclamped inductive switching. Designers must implement external clamping (e.g., RCD snubber or active clamp) to limit V_CE within 400 V during turn-off.
