Product details
Overview
UPTB5E3/TR13 from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) in DO-216AA package, rated for 5 V standoff voltage (VWM), 6.0 V minimum breakdown voltage (VBR @ 1 mA), and 1000 W peak pulse power (8/20 µs). It delivers sub-100 ps clamping response and is designed for ESD/EFT protection of low-voltage digital interfaces including USB, I²C, and GPIO lines.
For engineers reviewing the UPTB5E3/TR13 datasheet, UPTB5E3/TR13 pinout, UPTB5E3/TR13 application, or UPTB5E3/TR13 equivalent, key selection criteria include bidirectional polarity, 5 V working voltage compatibility with 3.3 V/5 V logic rails, IEC61000-4-2 Level 4 compliance, and tape-and-reel packaging for automated SMT assembly.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, triggering at ≥6.0 V to divert surge current away from downstream ICs. Its oxide-passivated silicon chip and high-temperature solder bonds ensure stable performance under repeated 8/20 µs transients up to 89.4 A.
The DO-216AA package features a full metallic cathode bottom tab acting as both thermal path and mechanical anchor, with integral locking tab enhancing heat dissipation and mounting reliability on FR4 PCBs with 1 oz copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5 V - Maximum continuous reverse/peak AC voltage before clamping; matches 3.3 V system rails with margin. |
| VBR @ 1 mA | 6.0 V min - Ensures reliable turn-on above normal operating voltage but below IC absolute maximum ratings. |
| IPP (8/20 µs) | 89.4 A - Supports IEC61000-4-5 Class 1 lightning surge (42 Ω source) up to 1 kV open-circuit. |
| VC @ 10 A | 9.5 V max - Clamped voltage stays below 10 V during 10 A transient, protecting 5 V-tolerant inputs. |
| Leakage @ VWM | 50 µA max - Low standby current avoids loading sensitive signal lines or battery-powered circuits. |
| TJ Range | –65 °C to +150 °C - Enables use in automotive under-hood and industrial control environments. |
Pinout & Package
DO-216AA surface-mount package with full metallic cathode bottom tab (Case = Cathode). Two-terminal device: Anode and Cathode terminals are accessed via top-side metallization; cathode connects directly to the metalized bottom surface for low-inductance grounding and thermal conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point in positive half-cycle | Connected to protected line; conducts when line voltage exceeds VBR relative to cathode. |
| Cathode (Tab) | Common reference and surge return path | Full-metal bottom serves as low-impedance ground connection and primary heat sink; must be soldered to large copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Protects AC-coupled or dual-polarity signals (e.g., RS-485, CAN, audio) without polarity constraints. |
| Clamping time < 100 ps | Responds faster than most interface ICs' internal ESD structures, preventing latch-up or damage during fast transients. |
| IEC61000-4-2/4-4 compliant | Validated for ±8 kV contact / ±15 kV air discharge ESD and 4 kV electrical fast transients (EFT). |
| RoHS-compliant e3 suffix | Matte-tin plating over copper ensures lead-free solderability per J-STD-020B Level 1 (no dry pack required). |
| Powermite package | Eliminates solder flux entrapment via void-free epoxy case and full-metal bottom; compatible with auto-insertion equipment. |
Applications
| USB 2.0 Data Lines | I²C Bus Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 peripherals against ESD events during hot-plug insertion. IC Role / Device Role: Bidirectional shunt TVS placed between differential pair and ground. Use Value: Clamps transients to ≤9.5 V while maintaining <50 µA leakage, preserving signal integrity and USB eye diagram compliance. | Use Scenario: Safeguarding SDA/SCL lines in microcontroller-based sensor networks exposed to board-level EFT. IC Role / Device Role: Low-capacitance bidirectional clamp on open-drain bus lines operating at 3.3 V. Use Value: Prevents false ACK/NACK due to transient-induced bus glitches, with no impact on rise/fall times (C ≈ 100 pF typical). |
| Industrial HMI Keypad Interface | Automotive Body Control Module Inputs |

IC Role / Device Role: Secondary surge protection stage after primary LC filtering, clamping to safe levels for 5 V logic inputs. Use Value: Rated for –65 °C to +150 °C operation and qualified to IEC61000-4-5 Class 1, supporting under-hood deployment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A | Unidirectional; 600 W (8/20 µs) rating; SMA package; higher VC = 9.2 V @ 10 A | Requires polarity-aware layout; not suitable for AC or bidirectional signal lines without external diodes. | Select when unidirectional protection suffices and lower cost is prioritized over bidirectional flexibility. |
| TPSMF5.0A | Unidirectional; 400 W (8/20 µs); SOD-123FL package; VC = 9.8 V @ 1 A | Limited surge handling; intended for lower-energy ESD only, not EFT or lightning surges. | Choose for space-constrained consumer electronics where IEC61000-4-2 compliance is primary requirement. |
Compared with SMBJ5.0A and TPSMF5.0A, UPTB5E3/TR13 provides true bidirectional clamping, higher 1000 W surge rating, and DO-216AA thermal performance-making it uniquely suited for robust industrial and automotive signal-line protection where polarity independence and repeatable surge endurance are mandatory.

FAQ
What is the polarity configuration of UPTB5E3/TR13?
UPTB5E3/TR13 is a bidirectional TVS diode, meaning it clamps voltage transients of either polarity relative to ground. Its marking code "B05▪" confirms bipolar functionality, enabling protection of AC-coupled or differential signal lines without concern for orientation during placement. This differs from unidirectional variants like UPT5e3 or UPT5Re3.
Does UPTB5E3/TR13 meet IEC61000-4-2 and IEC61000-4-4 standards?
Yes, UPTB5E3/TR13 is explicitly validated for IEC61000-4-2 (ESD immunity up to ±8 kV contact) and IEC61000-4-4 (EFT immunity up to 4 kV), as stated in the official Microsemi datasheet. These certifications apply directly to the UPTB5E3/TR13 device and are not inferred from family-level data.
What is the thermal resistance of UPTB5E3/TR13 when mounted on a standard PCB?
When mounted on an FR4 PCB with 1 oz copper, UPTB5E3/TR13 has a thermal resistance of 240 °C/W junction-to-ambient. With proper thermal pad design connecting the cathode tab to a large copper area, junction-to-tab resistance drops to 15 °C/W-critical for sustaining repetitive surge duty cycles.
Can UPTB5E3/TR13 replace UPT5e3 in an existing design?
No-UPTB5E3/TR13 cannot directly replace UPT5e3 because they differ in polarity: UPT5e3 is unidirectional (anode-to-tab), while UPTB5E3/TR13 is bidirectional. Swapping them risks improper clamping behavior on DC-biased lines. Layout and schematic review is required before substitution.
What does the "TR13" suffix indicate in UPTB5E3/TR13?
The "TR13" suffix denotes tape-and-reel packaging: 12 mm carrier tape, 13-inch reel, containing 12,000 units. This format is optimized for high-speed pick-and-place assembly and aligns with EIA-481-B standards. The base part UPTB5E3 remains electrically and mechanically identical.
