Product details
Overview
TPSMP13AHE3/84A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) in DO-220AA (SMP) package, with 12.4 V to 13.7 V breakdown voltage (VBR), 18.2 V clamping voltage (VC) at 22.0 A peak pulse current, and 400 W peak pulse power rating for VBR ≥ 13 V. It protects sensor signal lines and drive transistors in automotive ECUs.
For engineers reviewing the TPSMP13AHE3/84A datasheet, TPSMP13AHE3/84A pinout, TPSMP13AHE3/84A application, or TPSMP13AHE3/84A equivalent, key selection criteria include AEC-Q101 qualification, 1.0 mm profile for space-constrained PCBs, low incremental surge resistance, and RoHS-compliant matte tin terminations meeting JESD22-B102 solderability.
Technical Context
This TVS diode uses Vishay's patented PAR oxide-passivated chip construction to achieve excellent clamping performance and fast response time (<1 ns). Its unidirectional configuration provides reverse-biased overvoltage protection with defined cathode polarity indicated by a color band.
The device operates across -65 °C to +185 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. It delivers 400 W peak pulse power under 10/1000 µs waveform when mounted on 5.0 × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V - ensures reliable triggering above system stand-off voltage of 11.1 V |
| VC @ IPPM | 18.2 V at 22.0 A - limits transient voltage seen by protected IC to safe level |
| PPPM | 400 W - sustains high-energy transients common in 12 V automotive load-dump events |
| IFSM | 40 A - withstands repetitive 10 ms half-sine surge without degradation |
| TJ max | +185 °C - supports under-hood operation in engine control modules |
| Package | DO-220AA (SMP) - ultra-low 1.0 mm height enables placement beneath connectors or shields |
| AEC-Q101 | Qualified - certified for automotive electronics per stress test requirements |
Pinout & Package
DO-220AA (SMP) surface-mount package with two terminals: anode and cathode. Cathode denoted by color band. Matte tin-plated leads meet J-STD-002 and JESD22-B102 solderability standards; HE3 suffix indicates JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal in forward bias; connected to protected line in unidirectional clamp | Carries surge current into device during overvoltage event; must route with low-inductance path to ground |
| Cathode | Negative terminal; marked with color band; referenced to system ground | Serves as clamping reference node; requires solid low-impedance ground plane connection |
Key Features
| Feature | Design Value |
|---|---|
| Patented PAR oxide passivation | Enables stable VBR tolerance and long-term reliability under thermal cycling |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a) |
| MSL Level 1 rating | Allows single-reflow assembly without dry-pack or baking requirements |
| 1.0 mm typical height | Permits placement in tight spaces such as behind instrument cluster bezels or near camera modules |
| RoHS/WEEE compliant | Meets EU regulatory requirements for automotive supply chain traceability and end-of-life handling |
Applications
| Automotive Engine Control Unit (ECU) | Advanced Driver Assistance Systems (ADAS) Camera Interface |
|---|---|
Use Scenario: Protects microcontroller I/O pins and CAN transceiver inputs from load dump and jump-start surges in 12 V power domain. IC Role / Device Role: Unidirectional TVS placed between signal line and chassis ground to clamp negative-going transients. Use Value: Maintains 11.1 V stand-off while clamping to 18.2 V at 22 A, preventing latch-up or gate oxide damage in 3.3 V/5 V logic interfaces. |
Use Scenario: Shields MIPI CSI-2 differential pairs in surround-view cameras from ESD and board-level coupling noise. IC Role / Device Role: Low-capacitance TVS on each signal line, leveraging DO-220AA's minimal parasitic inductance. Use Value: 1.0 mm height avoids interference with lens housing; AEC-Q101 qualification ensures field reliability over 15-year vehicle life. |
| Electric Power Steering (EPS) Motor Driver | Body Control Module (BCM) LIN Bus Node |
Use Scenario: Guards gate drivers and current-sense amplifiers against inductive kickback from brushed DC motor commutation. IC Role / Device Role: High-power TVS on low-side switch source node and sense resistor connections. Use Value: 400 W peak power rating absorbs repeated 100–200 mJ energy pulses without degradation; 185 °C max TJ supports under-hood mounting. |
Use Scenario: Protects LIN transceiver input from battery disconnection spikes and electrostatic discharge in door modules. IC Role / Device Role: Standoff voltage of 11.1 V matches 12 V nominal bus; cathode tied to ground, anode to LIN line. Use Value: 1.0 µA leakage at VWM prevents false wake-up; unidirectional design avoids interfering with LIN dominant/recessive signaling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5A | DO-214AC (SMA) package; 13 V VBR; 300 W PPPM; higher 2.3 mm height | Limited to non-automotive or less space-constrained designs; not AEC-Q101 qualified | Select when cost sensitivity outweighs height and qualification requirements |
| TPSMAJ13A | Same VBR and PPPM as SMAJ13A-E3/5A but AEC-Q101 qualified; identical DO-214AC footprint | Drop-in replacement for legacy SMA layouts requiring automotive qualification | Choose if existing PCB uses SMA package and AEC-Q101 compliance is mandatory |
Compared with TPSMP13AHE3/84A, SMAJ13A-E3/5A offers lower cost but lacks AEC-Q101 and height advantage; TPSMAJ13A matches qualification but increases board area by 3.5× and height by 2.3×, limiting use in compact ADAS or EPS modules.

FAQ
What is the clamping voltage of the TPSMP13AHE3/84A at its rated peak pulse current?
The TPSMP13AHE3/84A has a maximum clamping voltage (VC) of 18.2 V at 22.0 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured with the device mounted on a PCB using 5.0 × 5.0 mm copper pads per terminal, ensuring repeatable thermal and electrical performance in production assemblies.
Is the TPSMP13AHE3/84A suitable for protecting CAN bus lines?
No - the TPSMP13AHE3/84A is a unidirectional TVS with 11.1 V stand-off voltage and 18.2 V clamping, making it unsuitable for bidirectional CAN bus protection which requires symmetric clamping around 0 V. For CAN FD or classical CAN, use bidirectional devices like SM712 or TPD2E001.
Does the TPSMP13AHE3/84A have a specified junction capacitance?
No junction capacitance (CJ) value is published for the TPSMP13AHE3/84A in the official Vishay datasheet (Doc. #88471). The family datasheet shows CJ curves only for VBR ≤ 12 V variants; for signal-line protection where capacitance matters, consider verified low-CJ alternatives like USBLC6-2SC6.
What does the "HE3/84A" suffix indicate in TPSMP13AHE3/84A?
The "HE3" denotes RoHS-compliant, high-reliability automotive grade with JESD201 Class 2 whisker resistance; "84A" specifies the preferred packaging: 7-inch plastic tape-and-reel with 3000 units per reel. This matches Vishay's ordering convention in Document #88471, Table "ORDERING INFORMATION".
How does the TPSMP13AHE3/84A compare to the TPSMP13HE3/84A in terms of electrical performance?
The TPSMP13AHE3/84A has tighter VBR tolerance (12.4–13.7 V) versus TPSMP13HE3/84A (11.7–14.3 V), lower leakage (1.0 µA max at VWM vs. 5.0 µA), and higher IPPM (22.0 A vs. 21.1 A), resulting in improved clamping consistency and surge margin for critical automotive nodes.
